Pagefile is the system's swap space. Windows uses a swap file to swap pages of memory to disk. It does this when physical memory is low and for pages that have not been referenced for a certain amount of time. To remove it, open Control Panel > System then click on Advanced tab then the Settings button under Performance Options then click the Advanced tab. Under the Virtual Memory section click the Change button and then find and click in the No Paging file button then click Set. Click OK to dismiss all windows ignoring any warnings. Reboot and then repeat the steps to re-create a pagefile that is 1.5 times your installed physical memory. Make sure the minimum and maximums match i.e. if you create a pagefile of 1024, put 1024 in both boxes. If you have a second hard drive, create the pagefile on that drive.
