Medical advantages of Sajda (Prostration) & The Miracle of Zam Zam Water

Now a days, in the world of twitter people read only 140 worrds.hope you have the patience of reading this long copy and paste.

http://www.aulia-e-hind.com/sajda.htm

Sajda (Prostration) is a unique position or stance in the regular prayers, which a Muslim is supposed to offer at least five times a day. Although the basic purpose of obligatory prayers is not to provide an exercise for people yet it is being increasingly recognized that it has plenty of medical advantages for the human body.

Here it is worth mentioning that Holy Prophet Muhammed (peace be upon him) has mentioned in a hadith in Ibn Maja:' That prayer is a cure for many diseases'. The position of Sajda in which the forehead touches the ground is exclusively associated with the Muslim form of prayer. It is the climax of a Muslim's prayer and as mentioned in a Hadith a Muslim is nearest to Allah in this position.

The messenger of Allah sallallahu alaihi wa sallam said: "The nearest a servant comes to his Lord is when he is prostrating himself, so make supplication' (in this state)" In a Hadith narrated by Anas bin Malik (R.A.) Holy Prophet (peace be upon him) advised Muslims to perform Rukuu (bowing) and Sajda(prostration) properly.

In another Hadith he sallallahu alaihi wa sallam advised to perform Sajda(Prostration) and Bowing calmly and to get up only when the body has come to ease. Hence the first positive effect upon a person who prostrates or does Sajda(Prostration) is that he comes nearest to Allah and hence in that condition he can supplicate.


Psychological advantage: 
This is a great psychological advantage and it gives relief to the person concerned as life is full of worries and in this position he gets at least a transient refuge from the agonizing problems.

When a person goes to the position of Sajda (Prostration), his whole body is in active motion. This position can be considered as a mini dive as the musalli (one who offers prayer) goes to rest his forehead on the ground while his hands are placed at the sides. This brings most of the body muscles if not all in active motion and serves to give them some exercise. The hands are then specifically stretched out and thence the forearm as well as arm muscles are supposed to bear the weight in the Sajda (Prostration) position. It gives good exercise to the muscles of the upper limb. The Prophet (peace be upon him) in a hadith advised not to put the forearms flatly on the ground but to keep them elevated above ground and this is better for the forearm and arm muscles.

Sajda (Prostration) is a unique position as this is the only position in which brain (or head) becomes lower than the heart and hence for the first time the blood gushes towards the brain with full force whereas in all other positions (even when lying) brain is above the heart when it has to work against gravity to send blood to the brain. In the position of Sajda (Prostration) due to the increased blood supply the brain receive more nourishment and it has good effect upon memory, vision, hearing, concentration, psyche and all other cognitive abilities.

People who offer their prayers regularly have more will power and can cope with the difficulties of life in a much better manner.

They have less incidence of headaches, psychological problems and other defects of cognitive function. In the unique position of Sajda(Prostration) the neck muscles get best exercise. They have to bear the load when the forehead lies at the ground hence the neck muscles become stronger. One can note the tense pressure at the neck muscles in the position of Sajda(Prostration) specially the active motion of the neck and the facial muscles when the head is being lifted. (e.g. one inch above the ground) and it will be noticed that they are in a very active motion.

More strong cervical muscles mean the cervical vertebra will be better protected. Strength of cervical muscles is important as the head rests upon cervical vertebra supported by cervical musculature. In fact head performs rotator movements over the cervical vertebra. In any accident cervical neck examination is especially important to the physicians because of its extraordinary importance. It is uncommon that a person who offers his prayers regularly will get the usual neck myalgias or cervical spondylosis as the neck muscles particularly become very strong due to the 34 sajdas(Prostrations) offered daily in five prayers.

The unique position of Sajda (Prostration) also has positive effects upon the back muscles as while going into Sajda and getting up from it the back muscle contract actively and they become stronger. Probably it is because of this reason that a person who is regular in prayers will (rarely) get backache.

Finally it must be reminded that (even though) prayer is not meant to be an exercise, there are a lot of medical advantages associated with it.. Still the best blessing is the peace of mind, which a person derives by the accomplishment of his duty to Allah by fulfilling an obligation.

Secrets of Remedy by Dates - Khajoor

Prophet Muhammad (PBUH) gave a special attention for Dates as part of the believer's diet especially during the Holy month Ramadan. Allah Almighty mentioned Palm trees many times in the Quraan, and made it the food of the dwellers of Paradise, So what are the secrets of this great nutriment? Is it possible to think of using dates as remedy for some diseases? What do scientists of today say about dates?

Dates are one of the most nourishing fruits and It's called sometimes "Bread of Desert", More than two third of dates' weight is natural sugar. This fruit was highly esteemed by the ancient civilizations more than 5000 years ago; ancient Egyptians considered dates as a symbol of fertility, while the Romans and the Greeks used it to ornament their stately triumph pageants[1]. Today, dates are widely-grown in the Arabian Peninsula, Iran, Egypt, Iraq, Spain, Italy and the United States. There are more than 600 varieties of dates[2].

Next, we are going to explore the usefulness of dates to humans throughout the different stages of their lives.

Dates and the Prebirth period

Dates stimulate the uterus by regulating And brisking it's contractions which facilitate delivery. The uterus is a relatively large muscular organ and it urgently requires an adequate supply of natural sugar during labor and delivery. Being laxative, dates are essential for pregnant women before delivery in order to purge the colon and intestine and to facilitate delivery. The miraculousness of the Quranic verse shows evidently as Allah tells Mary: (And shake the trunk of the palm tree towards thee – thou wilt cause ripe dates to fall upon thee) [Mariam – 25]

Nutriment and medicine for children

Dates contain natural sugar which is easily absorbed and digested, thus, it is safe and comforting for children's stomach and intestine. And the dates juice is useful especially if we mix it with Milk to become very nourishing and restorative drink for children and adults. Dates and honey paste is used for the treatment of diarrhea and dysentery in children but it should be taken three times a day.

This paste also comforts and hardening the gums during teething and facilitates the process.

It is advisable to purchase the good varieties of dates and to wash them thoroughly before use especially when used as food or remedy for children. Here, we should mention the prophetic tradition of (Al Tahneek); rubbing the newborn's mouth with a well-chewed date and feeding him with it. Science has proved that giving the newborn some sugar dissolved in water provides the child with the necessary nutrition and improves their immunity against diseases.

And when we know that sugar in dates is the most easily absorbed and digested type of sugar so it will be suitable nutriment for newborns but the dates should be well-chewed or soaked in water to be easy for the newborn to take. This proves that the great prophet (PBUH) preceded today's doctors to this type of nutrition. It's no wonder that he preceded them as he is the messenger of their God.

Figure (1) Dates are the best nutriment for newborns since pregnancy and during breast feeding

An effective treatment for constipation

Dates can be used in the treatment of intestinal disturbances and it also helps the intestine perform their function effectively, and helps establishing a colony of friendly bacteria in the intestines. Dates are also highly beneficial in the treatment of constipation as the roughage provided by it stimulates sluggish bowels. They should be immersed in water at night and taken after making them into fine syrup the next morning to secure laxative effect [3].

A Remedy for Sexual Debility

Date syrup can be used as a treatment for weak heart. It can also be use for the treatment of sexual weakness. When it's mixed with milk and honey, dates can be used as a tonic for the treatment of sexual disturbances for both sexes, And such syrup strengthens the body and raises its energy levels. The elderly would benefit from this syrup too. It improves their stamina and purges their bodies from the toxins that have accumulated in their cells along the years.

An Ideal Nutriment for Fasters

It was very weird that western physicians who treat their patients by fasting advise them by taking the natural sugar in fruits and water when breaking the fast [4]. And when we know that dates contain a high ratio of such easily-absorbed sugar then dates and water are the best nutriments for fasters.

Here we remember the Hadith of our prophet (PBUH) : (When any of you breaks his fasting he should eat dates cause dates are blessing, if he didn't find dates then drink water cause water is purifying) [Narrated by Abo Dawood].Here we see that the prophet (PBUH) showed us the principles of effective fasting, by eating dates and drinking water at breakfast centuries before Westerns.

The prophetic wisdom out of having Dates for breakfast might be reduce the hunger and consequently, reduce the amounts of food consumed; therefore the fasting will be effective and useful. And if we remember that fasting consider the best weapon to excise toxics out of the body, then having dates ( toxin-resistive ) when you break your fast represent a real integrated treatment against weakness and fatigue resulted from the accumulation of toxic chemicals and heavy metals in the cells of the body.

Figures (2) Date lose 1/3 of their water content when dried in the sun. Dried dates contain a high ratio of natural sugar hence; they are the best food for fasters

A Treatment for Obesity

The wide variety of nutritious elements in dates makes it hunger-resistive! And when we know that the cause behind Obesity is a persisting feeling of hunger and an appetite for food which drives a person to consume larger amounts of fats and sugar when he eat his meal. So treatment by eating few dates when feeling hungry helps reduce hunger and be filled. These dates will provide the body with the necessary sugar and stimulate the intestine which reduce hunger greatly, and eventually, reduce food consumption. The miraculousness of the prophet's saying shows as he said: (A household that has dates doesn't feel hunger) [narrated by Muslim]. We can conclude that dates can be used to treat Obesity!.

A Remedy for Lever and Inflammations

Dates remedy Lever and purge it from toxins, Breaking the fast with dates, is one of the most magnificent of natural remedies for the maintenance and purging the Lever from accumulated toxins. And also drinking dates juice could be used in the treatment of sore throat, various types of fever, rhinorrhia and common cold[5].

A Remedy for Intoxication

Dates are an excellent remedy for alcoholic intoxication. In such a case, drinking water in which fresh dates have been rubbed or soaked will bring quick relief[3]. Here we'd like to mention one of the prophet's (PBUH) Hadith in which he referred to dates as a remedy for intoxication. Prophet (PBUH) said: (Who eats 7 pressed dates in the morning, will not be inflected with witchcraft or poisoning that day) [Narrated by Abu Dawood]

If we deeply study the medical implications of the Hadith, we realize its miraculousness:

1- The prophet (PBUH) used the number 7. This number has significance in the universe, the Quran and the prophetic tradition. It's enough to know that the first number mentioned in the Quran was Number 7.

2- 7 dates weigh approximately 70 grams which provides a sufficient intake of a wide variety of minerals, salts and vitamins for the body.

3- This amount is sufficient to purge the body from the accumulated toxins in the cells; like heavy metals, lead as an example. The accumulation of toxins has increased nowadays due to widespread water, air and food pollution.

4- The Hadith implicitly referred to the toxins entering the body as (Poison). He also indicated that eating dates reduces the dangers such toxins impose the body to.

5- As for the word (Witchcraft); only God knows what was meant with it.

6- The Hadith doesn't imply that taking poison after eating seven dates would be completely harmless, In fact, doing this deliberately is considered as harming one's self on purpose and this is forbidden in Islam. But we have to undersand that Hadith means that eating seven dates each morning reduces the harmful effects of toxicants. In order to make the process more effective, regularity with eating seven dates in the morning should be maintained. As our Prophet (PBUH) asked us to do.

And we should understand from the Hadith that eating dates everyday regularly And in order will effect our psychological state and make it more stable, God only know the truth.

Figure (3) All the parts of the palm tree are beneficial! The leaves are for building house roofs; the wood is for heating; dates are highly nutritious, even date seeds can be immersed in water and given to horses, camels and hens as perfect food.

Date in numbers:

Having high medical and nutritious value, dates are expected to be the best food for the future. Dates contain as high a percentage as 88% of carbohydrate (starch), (2.5-5%) of fat, (2.3-5.6%) of Protein and (6.4-11.5%) of Vitamins and dietary fibre. The flesh contains (0.2 – 5%) of oil, whereas the seed's weight is (7.7 -9.7%) oil. The weight of the seed is (6.6 – 14.2%) of the date's weight.

Dates contain Vitamins A, B1 and B2, And contain Fluorine who defeats teeth decay. Other minerals that are found in various proportions in dates include boron, calcium, cobalt, copper, iron, magnesium, manganese, potassium, phosphorous, sodium and zinc. Additionally, the seeds contain aluminum, cadmium, chloride, lead and sulphur in various proportions. Selenium, element believed to help prevent cancer and important in immune function, is also found in dates.

For all of the previously mentioned benefits, date is the ideal food for the future. The fruit's production has increased 3 times over 40 years, whereas the world population has only doubled, an indication to the rapid growth of the production of this ideal fruit[1].

And finally...

Dear Believer if you are feeling weak, don't hesitate to take 7 dates in the morning as the prophet (PBUH) recommended. those Seven dates weigh around 70 gm, so if you take them, then you actually took 70 milligrams of calcium - which is very useful for the bones, joints and nerves, 35 milligrams of phosphorus which is nutritious to the brain and 7 milligrams of iron which is strengthens the body in general and the heart in particular.

It's also suitable for reducing weight as it only contains 0.25 gm of fat. So if you suffer from Obesity, then this meal is the right thing for you. This prophetic meal regulates and stimulates the bowels with the10 gm of dietary fiber it contains.

So won't you say yes to the prophetic advice?!


 

The Miracle of Zam Zam Water

Research by Tariq Hussain and Moin Uddin Ahmed. Come the Hajj season, and I am reminded of the wonders of Zumzum water. Let me go back to how it all started. In 1971, an Egyptian doctor wrote to the European Press, a letter saying that Zumzum water was not fit for drinking purposes. I immediately thought that this was just a form of prejudice against the Muslims and that since his statement was based on the assumption that since the Ka'aba was a shallow place (below sea level) and located in the center of the city of Makkah, the wastewater of the city collecting through the drains fell into well holding the water.

Fortunately, the news came to King Faisal's ears who got extremely angry and decided to disprove the Egyptian doctor's provocative statement. He immediately ordered the Ministry of Agriculture and Water Resources to investigate and send samples of Zumzum water to European laboratories for testing the potability of the water.

The ministry then instructed the Jeddah Power and Desalination Plants to carry out this task. It was here that I was employed as a desalting engineer (chemical engineer to produce drinking water from sea water). I was chosen to carry out this assignment. At this stage, I remember that I had no idea what the well holding the water looked like. I went to Makkah and reported to the authorities at the Ka'aba explaining my purpose of visit.

They deputed a man to give me whatever help was required. When we reached the well, it was hard for me to believe that a pool of water, more like a small pond, about 18 by 14 feet, was the well that supplied millions of gallons of water every year to hajis ever since it came into existence at the time of Hazrat Ibrahim A.S., many, many centuries ago. I started my investigations and took the dimensions of the well. I asked the man to show me the depth of the well.

First he took a shower and descended into the water. Then he straightened his body. I saw that the water level came up to just above his shoulders. His height was around five feet, eight inches. He then started moving from one corner to the other in the well (standing all the while since he was not allowed to dip his head into the water) in search of any inlet or pipeline inside the well to see from where the water came in. However, the man reported that he could not find any inlet or pipeline inside the well.

I thought of another idea. The water could be withdrawn rapidly with the help of a big transfer pump which was installed at the well for the Zumzum water storage tanks. In this way, the water level would drop enabling us to locate the point of entry of the water. Surprisingly, nothing was observed during the pumping period, but I knew that this was the only method by which you could find the entrance of the water to the well. So I decided to repeat the process. But this time I instructed the man to stand still at one place and carefully observe any unusual thing happening inside the well. After a while, he suddenly raised his hands and shouted, "Alhamdollillah! I have found it. The sand is dancing beneath my feet as the water oozes out of the bed of the well."

Then he moved around the well during the pumping period and noticed the same phenomenon everywhere in the well. Actually the flow of water into the well through the bed was equal at every point, thus keeping the level of the water steady. After I finished my observations I took the samples of the water for European laboratories to test. Before I left the Ka'aba, I asked the authorities about the other wells around Makkah.

I was told that these wells were mostly dry. When I reached my office in Jeddah I reported my findings to my boss who listened with great interest but made a very irrational comment that the Zumzum well could be internally connected to the Red Sea . How was it possible when Makkah is about 75 kilometres away from the sea and the wells located before the city usually remains dry? The results of the water samples tested by the European laboratories and the one We analysed in our own laboratory were found to be almost identical.

The difference between Zumzum water and other water (city water) was in the quantity of calcium and magnesium salts.

The content of these was slightly higher in Zumzum water. This may be why this water refreshes tired hajis, but more significantly, the water contained fluorides that have an effective germicidal action. Moreover, the remarks of the European laboratories showed that the water was fit for drinking.

Hence the statement made by the Egyptian doctor was proved false. When this was reported to King Faisal he was extremely pleased and ordered the contradiction of the report in the European Press. In a way, it was a blessing that this study was undertaken to show the chemical composition of the water. In fact, the more you explore, the more wonders surface and you find yourself believing implicitly in the miracles of this water that God bestowed as a gift on the faithful coming from far and wide to the desert land for pilgrimage.

Let me sum up some of the features of Zumzum water. This well has never dried up. On the contrary it has always fulfilled the demand for water. It has always maintained the same salt composition and taste ever since it came into existence. Its potability has always been universally recognised as pilgrims from all over the world visit Ka'aba every year for Hajj and umrah, but have never complained about it. Instead, they have always enjoyed the water that refreshes them. Water tastes different at different places.

Zumzum water's appeal has always been universal. This water has never been chemically treated or chlorinated as is the case with water pumped into the cities. Biological growth and vegetation usually takes place in most wells. This makes the water unpalatable owing to the growth of algae causing taste and odour problems.

But in the case of the Zumzum water well, there wasn't any sign of biological growth. Centuries ago, Hagar (raa) searched desperately for water in the hills of Safa and Marwa to give to her newly born son Ismail (pbuh) As she ran from one place to another in search of water, her child rubbed his feet against the sand. A pool of water surfaced, and by the grace of God, shaped itself into a well which came to be called Zumzum water.

Health Risks People Take

1. Lack of exercise : You must go for morning walk, atleast one KM every day.Regular exercise improves the immune system, gives you positive energy and keep you in good mood throughout.
2.Lack of sleep. Try to get sufficient amount of sleep.Normally a person requires seven hoursv of sleep.
 
3.Lack of water : Neither juice nor tea can replace the benefits guaranteed by water, but be sure to make it a rule to drink at least 8 glasses of water every day. This will make you more energetic, protects the immune system and also prevents dehydration that can result in headaches and muscle pains. So ensure that there is a water bottle at your desk and prevent headaches amidst your work and meetings.
 
4. Lack of proper meal : Never skip a meal. In the long run it will play havoc with your system.
 
5.Dining out frequently: Go for home food. Avoid outside food as much as possible as you dont know how these foods are prepared.

DAF Clarifier in Paper Mill waste water

FLOTATION PROCESS
DAFTECH Floatcells are circular in shape, ranging in diameter from 1.2 to 21.3 meters and a liquid depth of only 0.65 meter. The complete set up consists of a flotation tank, feed pump, pressure pump, compressor, air mixing tube, chemical feed system and a spiral scoop for collection and removal of floated sludge.

The inlet, outlet and sludge removal mechanisms are contained in the central rotating section. This section and the spiral scoop rotate around the tank at a speed synchronized with the flow. The system is operated in the recycle flow pressurization mode where a portion of clarified effluent (25 - 30 percent) is continuously recycled from the collection tank to the air mixing tube at about 6.5 bar pressure. After pressure release, the aerated water is mixed with the influent flow just before the inlet to the distribution duct that moves with the same velocity, but in opposite direction to the incoming flow thus creating a quiescent state in the flotation chamber. Fine bubbles generated in this manner attach to the suspended particles and make them float to the surface.

The spiral scoop takes up the floated sludge, pouring it into the stationary center section where it is discharged by gravity. Clarified water is removed by extraction pipes, which are attached to the moving center section and discharged. Wiper blades attached to the moving distribution duct scrape the bottom and the sides of the tank and discharge settled sludge into the built-in sump for periodic purging. The variable speed gear motor drives the rotating elements and scoop. Electrical current for the gear motor is fed from a rotary contact mounted on the central shaft.


AIR MIXING
The separation efficiency of Total Suspended Solids in a DAF cell depends substantially on the generation of uniformly sized microscopic air bubbles. 

A part of the clarified water, generally 25 to 30% of the feed rate, is pressurized through a centrifugal pump to about 65 meter head and let into a cylindrical Air Mixing Tube through a nozzle at one end. The nozzle is so oriented inside the tank that the jet of water churns spirally along the inside wall of the tube forming a vortex along the central axis of the tube.

Into this tube is brought compressed air which passes through a microscopically porous medium placed adjacent to the inside wall of the tube.

The tube produces a saturated air-water mixture because the rate of absorption of any gas in a liquid is directly proportional to the pressure in which the dissolution takes place.

The air-water mixture that comes out of the other end of the tube passes through a pressure release valve where the pressure is reduced to the level of the incoming wastewater feed. At this stage, air bubbles of 30 - 50 microns are produced profusely which get released into the wastewater thereby giving the necessary buoyancy
to the suspended solids to rise to the surface of the water in the flotation tank.


ZERO VELOCITY
A quiescent state is an absolute necessity for good flotation. This is achieved by ensuring zero velocity of the wastewater when it enters the flotation tank.

The feed of wastewater premixed with depressurized recycle stream is led into the main tank through a distribution tube with adjustable nozzles. It is then discharged into the tank through baffles and then a turbulence arrester. The rotational velocity of the incoming wastewater into the tank is counterbalanced by the mechanical movement of the distribution tube in the opposite direction but at the same speed. This ensures quiescent condition and minimum turbulence.

DAFTECH Floatcells are designed with a retention time of 3 minutes. The equipment therefore is much more compact than rectangular DAF clarifiers of 15 to 30 minutes of retention and occupies only half of the floor space.

Recycling of plastic

I wonder how will I be able to do away with this cheapest and lightest means of carrying my luggage.

These plastic bags and bottles have been our greatest friends in routine life. But, these friends of ours are severely putting a strain on the environment. Discarding plastic waste in open chokes the water bodies, clogs soil pores, blocks the drainage system. Not only this, the plastic waste when gets mixed and clogged with other waste emits harmful gases. If the same plastic becomes the food for fish, it means only death for them.

What can be done to reduce the side effects of plastic waste? Recycling of plastic is the best way to reduce the burden on the environment. Lets begin with not throwing the plastic bottles and bags in open. Secondly, make use of the use-and-throw bottles after cleansing them and re-using them for some other purpose.

Having Windows XP Slow Shutdown Problems?

Having Windows XP Slow Shutdown Problems?

Source of Article; http://www.windowsxpslowstartup.how-do-you-do.info/

Have a Windows XP slow shutdown problem? Waiting to go to bed and you want to make sure your PC powers down? Maybe you are just waiting for it to reboot.  it may take more time to complete the shutdown process. So what is is causing this Windows XP slow shutdown problem? A slow shutdown can be caused for a number of reasons. One thing that can cause this is the Windows XP page file.

By default Windows XP when shutting down goes through a process of clearing the page file. This page file is commonly called "virtual memory" and is used to swap pages of "real" memory to this "virtual memory" that resides on your hard disk. The smaller you real memory is (ram) the higher the memory swapping activity. Although this in itself will not cause the Windows XP slow shutdown problem it tends to make the running of programs slow during normal running. During the shutdown though it takes time to clear all the Virtual Memory as being on disk the access to it is slower than real memory. Unfortunately the clearing of virtual memory option is usually set by default.

So why is this so? Well for some reason Microsoft for some reason seemed to think that a large proportion of people buying a PC with Windows XP installed are going to run other operating systems as well as Windows XP (e.g. Linux etc.). This meant that a virtual memory that is not cleared can cause problems when switching between operating systems. Considering that only a very small proportion of users would be doing this you wonder why this option was enabled rather than disabled by default.

As I mentioned this option is enabled, it causes the system pagefile to be cleared upon a clean shutdown. This takes considerable time for the Windows XP operating system to flush out the pagefiles, thus causing your Windows XP slow shutdown problem. Fortunately can turn this option off and improve shutdown times. At the same time if you just happen to be one of those people who does run multiple operating systems then the cache still remains intact and accessible for the other operating system.

So let me show you how to turn this option off. You have to use the registry editor to do this.

  1. Start the registry editor by clicking on "Start" then on "Run"
  2. Type in the run box "Regedit" then click "OK"
  3. First perform a save of the registry by clicking on "File" then "Export" and save a copy of the whole registry. (Just in case you have to copy it back)
  4. Click on the "+" sign next to the following folders "HKEY_LOCAL_MACHINE" then "SYSTEM".
  5. Under this folder click on the  "+" sign next to the following "CurrentControlSet" then "Control" then "Session Manager" and lastly click on the folder icon labeled "Memory Management"
  6. Under the "Memory Management" folder look for the key called "ClearPageFileAtShutdown" If the value is already set to "0" then you have nothing to do. Your Windows XP slow shutdown problem is not this. Just exit the Regedit editor.
  7. If it is set to "1" then right click on the key and click on "modify"
  8. Change the  "Value Data" to "0" then click "OK"

And that's it! Well for you it may be.

Not quite, if you are having a Windows XP slow shutdown problem and you have Windows XP Professional installed then you are lucky. You do not have to go through all the above heavy stuff. (I guess they have to give you something for all that extra dosh you paid out) You can turn off virtual memory clearing as follows:

  1. Click on "Start" then "Run".
  2. Type in "secpol.msc" in the run box then "OK".
  3. Click on the "Security Options" folder.
  4. In the right panel look for the policy called "Shutdown:Clear virtual memory pagefile" and double left click on it.
  5. In the box that pops up left click on the "disabled" button then "OK".

That's all, don't you wish you had Windows XP Professional.

To conclude, there are many other things that can cause Windows XP slow shutdown problems. Many of the fixes suggested for the Windows XP slow startup problem can also be applied. (Cleanup disk, defragment etc). These are explained elsewhere on this website.
