Re-boot your system.
Next, we need to remove the "hidden" and "system" file attributes from the page file.
Bring up an Admin CMD prompt -
Type or paste the following into the CMD screen:
Code:
attrib -s -h %systemdrive%\pagefile.sys
When complete, leave the CMD screen open for now.
Next - delete the page file.
You can use Windows Explorer -- locate c:\pagefile.sys, RIGHT-click on the file, press & hold the left SHIFT key down while clicking on DELETE. This is called a "hard delete" - it will bypass the Recycle Bin. A hard-delete is preferred as the page file may be too large for the Recycle Bin or in cases of low hard disk space.
My preferred method - delete the page file via CMD. Type/paste the following into the Admin CMD screen left open from the ATTRIB step. If you closed the CMD, screen, simply follow the instructions to open a new Admin CMD screen -
Code:
del /a /q %systemdrive%\pagefile.sys
Deletion of Paging Files on Drives other than c: (System Drive)
Drive c: is the usual designation for the system drive (or "OS drive"). You can delete page file(s) from other drives or partitions via Windows Explorer or by substituting the drive letter for %systemdrive% in the CMD screen.

Deletion of Paging Files on Drives other than c: (System Drive)
Deletion of Paging Files on Drives other than c: (System Drive)
Example: To delete a paging file on drive j: - substitute j:\pagefile.sys for %systemdrive%\pagefile.sys
For info, %systemdrive% is an environment variable (ENV VAR). The system/OS drive/partition letter followed by a colon (:) is substituted by Windows for the ENV VAR as can be seen here by a simple CMD ECHO command - (hover mouse over image to enlarge it) -

Time to reallocate the Page File/ Turn virtual memory back on.
Go back into the page file screen - follow the above steps except for the last one.
Check Box #1 to allow Windows to manage paging files; then click on OK -
