Virtual memory is not the pagefile and it is not an extension of physical RAM. It is always in use and cannot be disabled.<br /><br />Virtual memory is a system that provides a consistent environemnt to applications that is independent of the size of RAM. Every application sees a virtual address space of 4GB. The lower 2GB is private (not shared) to each process while the upper 2GB is used by the system. Physical RAM is mapped into this address space according to both need and availability.<br /><br />NOTE: this is virtual address space and is completely independent of RAM size.<br /><br />Physical memory acts as a cache of the hard disk. RAM is used to hold frequently used data while the disk holds the remainder. The pagefile is as temporary storage for infrequently used modified data. Application code is not normally written to the pagefile as it can simply be reloaded from the original files.<br /><br />Best advice regarding the pagefile: Unless you have a very specific need, leave it on system managed. The large majority of computer users will be well served by this setting. Many VERY experienced users use this setting.<br /><br />Windows designers understand memory management and the pagefile better than you do.<br /><br />Larry Miller<br />Microsoft MCSAlmiller7https://www.blogger.com/profile/01390276023955121113noreply@blogger.com
