Clrear windows XP virtual memory on shutdown

Written by IT News on 10:37 PM

What is Virtual Memory? and what is the page file? In any windows disk partition by default will exist page file, some times the file is bigger day after day. So, what is the page file for? can we delete or just not activate it? Here you will lear a litle bit about virtual memory and how to clear it when windows shuting down.

Virtual memory is a program instruction on an Intel 386 or later CPU can address up to 4GB of memory, using its full 32 bits. This is normally far more than the RAM of the machine. (The 32nd exponent of 2 is exactly 4,294,967,296, or 4 GB. 32 binary digits allow the
representation of 4,294,967,296 numbers — counting 0.)

The page file in XP is a hidden file called pagefile.sys. It is regenerated at each boot — there is no need to include it in a backup.

To see it you need to have
Folder Options | View set to ‘Show Hidden and System files’, and not to ‘Hide Protected mode System files’. Just if you feel need to clear the cache or page file size, here is to do that on shuting down:

  • Go to Control panel Administrative tools, local security policy.
  • then goto local policies ---> security options. Then change the option for "Shutdown: Clear Virtual Memory Pagefile"
