How to solve virtual memory shortage in Windows XP system

        After more than a decade of glory, Windows XP will stop providing various patch services to users (how to face the retirement of Windows XP). Windows XP was released on October 25, 2001. It has been 11 years since then. During this period, Microsoft has also released three new versions of Windows (Vista in 2007, Windows 7 in 2009 and Windows 8 in last year). Even with the deadline, there are still many PCs running this system. In recent use, many friends will find out that there are not many programs, but there are often system prompts for insufficient virtual memory. How to solve these problems?
1, anti-virus Some viruses will take up a lot of memory space, resulting in the system has insufficient memory. Hurry up to kill the virus, upgrade the virus database, and then do the anti-virus measures.
2, reasonable setting of virtual memory virtual memory settings can also lead to memory shortages. In general, the virtual memory size is twice the size of the physical memory. If it is set too small, it will affect the normal operation of the system program.
Resize the virtual memory, right click on "My Computer", select "Properties", then on the "Advanced" tab, click the "Settings" button in the performance box, switch to the "Advanced" tab, then Click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and restart the system after you finish.
3, adjust the system space virtual memory file is placed in the system disk by default, such as WindowsXP virtual memory file named "pagefile.sys", if the remaining space of the system disk is too small, it will lead to the problem of insufficient virtual memory.
The system must retain at least 300MB of free space, of course, this value depends on the actual needs of users. Users should try not to install various application software on the system disk. It should ensure that there is enough space for virtual memory files to use, and it is better to place virtual memory files on non-system disks.
4, modify system user permissions Based on the NT kernel Windows system startup, system users will create virtual memory files for the system. Some users use the NTFS file system for system security, but they cancel the system user's "write" and "modify" permissions on the system disk, so that virtual memory files cannot be created for the system. When running large programs, it will also appear. The problem of insufficient memory.
The problem is solved very well, as long as the system user is given the "write" and "modify" permissions, but this is limited to users who use the NTFS file system.
