This article explains how to set Pagefile.sys to delete automatically on shutdown in Windows 10. Windows 10 automatically creates a Pagefile as you use the operating system. It is a paging file that contains virtual memory for the OS. By default, this memory is the same in size as the physical RAM you have on the system. This virtual memory is reserved on the disk and used to store the programs that are not being used to relieve the RAM.

From the advanced system settings, you can configure the virtual memory accordingly. You can pick a disk for virtual memory and define its size. If there are multiple disk parts in the system then you can reserve virtual memory from any or all of the disks. Now the disadvantage of Pagefile.sys is that it saves files on the disk and hence can occupy a significant amount of the storage. Windows can function normally if you don’t clear the page memory but I can present a security risk. To avoid that, you can configure the Windows to delete Pagefile.sys automatically on system shutdown.
