If you want to boost your time o windows xp to load and perform faster and better, you can place the kernal in windows xp in the RAM rather than having it in the paging file.
Please Note : You should have RAM above 256MB to do this change.
Follow the below steps.
1. Click the “Start” Button.
2. Select the “Run” command and type “regedit” and press “Enter“.
3. Then go to the following key.
4.HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\
MemoryManagement\DisablePaging Executive
5. Change the value to “1” to disable paging.
6. Exit the Registry and reboot the computer.
7. Now your kernal will always run in your RAM.
Note : Set the value to “0” to undo and then the kernal will again run in your paging file.

Can we use this tweak for Windows Vista as well??
I think it must work with windows Vista also. But I am not sure.If you try it in Vista, inform me the result..
The advantages and disadvantages of this tweak are not nearly as clear cut as implied. It is not a matter of choosing where the kernel will be: in memory or disk. As an essential component, Windows will attempt to keep the kernel in RAM whenever possible, only unloading it when under heavy memory load. If you have a lot of RAM this is not likely to occur very often. This setting prevents Windows from doing this. If Windows can not unload the pageable kernel it will be forced to unload something else, probably something of equal or greater importance.
Windows designers know more about memory management than you do. This setting was turned off for good reasons.
Best advice: LEAVE IT ALONE. The real experts do.

I read Larry’s reply with great interest. I’m an experienced user. I have tried the registry change to move the kernel into RAM. I’ve tried the at least three times. I have never found that it changed the the size of either paged or unpaged kernel as indicated by Task Manager. Presently the paged memory is 198MB, unpaged 29MB. I have 4 GB memory. Can you suggest a reason why I have noticed no change? What might I have done wrong?
I wouldn’t try this unless you have 2 Gb memory. I do, even so I don’t know about making this change. Though the theory behind it is sound.
