You need some disk space urgently? Well, you could either look into our guide how to free up disk space in Windows 7 or follow the instructions after the break to delete the pagefile.sys (not recommended)!
What is the pagefile.sys and why shouldn’t I delete it?
The pagefile.sys is the virtual memory file that is saved on your hard drive. Therefore this file can become quite big. Whenever you don’t have enough physical RAM the system can use the virtual RAM to speed up the current process. So, the virtual memory is quite essential for a fast system and it is not recommended to disable it. Even on systems with a lot of RAM you will need this file badly. Actually, the more physical RAM you have, the more virtual memory you should have. As a rule of thumb, you should always have 1.5 times more virtual memory than physical RAM, recommended is 2 times more.
As you can see, deleting the pagefile.sys is not a good solution and you should only do it if you need disk space urgently.
ALTERNATIVE: It may be a better alternative to delete the hiberfil.sys (the hibernation file) and stop using hibernation while you are low on disk space.

9. Step Uncheck Automatically manage paging file size for all drives
10. Step Check No paging file and click on Set
11. Click on Ok and reboot. The pagefile.sys will be gone for good you don’t even have to delete it.
