The default settings of the Windows page file in Windows 98 is "Let Windows Manage My Virtual Memory." But since Windows XP came out it has been known among tweakers to set the the minimum and maximum values of the page file. In fact, the default setting of the page file in Windows XP is set according to how much RAM you have installed during the installation of Windows. If you add RAM you should enter the new values in according to the information I pasted from Microsoft below. It would always be best to run Scan Disk (or Check Disk) and defrag after changing the size of your page file. The settings for Windows XP can be applied to Windows 9x operating systems. (I always set the minimum and maximum values of my virutal memory in Windows 98SE. The best results occur if you install your memory, install Windows and then defrag right afterwards.)
HOW TO: Set Performance Options in Windows XP
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
Click Start, click Control Panel, click Performance and Maintenance, and then click System.
Click the Advanced tab, and then click Settings under Performance.
Click the Advanced tab, and then click Change under Virtual memory.
Under Drive [Volume Label], click the drive that contains the paging file you want to change.
Under Paging file size for selected drive, click Custom size, type a new paging file size in megabytes (MB) in the Initial size (MB) or Maximum size (MB) box, and then click Set.
If you decrease the size of either the initial or maximum paging file settings, you must restart your computer to see the effects of those changes. When you increase the paging file size, you typically do not need to restart your computer.
Notes
To have Windows choose the best paging file size, click System managed size. The recommended minimum size is equivalent to 1.5 times the amount of RAM on your system, and 3 times that figure for the maximum size. Example, if you have 256 MB of RAM, the minimum size would be 384, the maximum size would be 1152.
For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. The recommended size is equivalent to 1.5 times the amount of RAM on your system. Usually, you should leave the paging file at its recommended size, although you might increase its size if you routinely use programs that require a lot of memory.
To delete a paging file, set both initial size and maximum size to zero, or click No paging file. Microsoft strongly recommends that you do not disable or delete the paging file.
