All versions of Windows— including XP— let you adjust the "virtual memory" or "page file" or "swapfile" space:
Fred, I just bought a new PC running Windows XP. It has 1.3 G Hz CPU, 128 MB RAM and 32 GB hard drive. My question: Is there a rule of thumb for the paging file size settings with different amounts of RAM, drive space and CPU speed in order to maximize performance? I don’t run a lot of memory intensive applications. The most intensive application I run is PrintShop. If you can suggest some Web sites that might have some recommendations on paging file settings for maximum performance I would appreciate them. Thanks in advance, Mark J. Rote
Actually, XP and Windows 2000 both will suggest a reasonable "recommended" size for their virtual memory settings, and also tell you the minimum and maximum allowable sizes. In XP, right click "my computer," then select properties/advanced/performance settings/advanced/change (virtual memory).

In Win2K, right click "my computer," then select properties/advanced/performance options/change (virtual memory).
