As afore mentioned, the pagefile mirrors the physical memory, just move it to another partition, or manually shrink it,
In the Start Menu search box, type "Advanced System Settings" and choose the Control Panel applet that should show up, "View advanced system settings"
Under "Advanced" tab, "Performance" section, click "Settings..."
Under "Advanced" tab, "Virtual Memory" section, click "Change..."
These are the actual settings. Uncheck "Automatically manage paging file size for all drives" and you can change these settings. Highlight the drive you want it on, and select either a fixed size or system managed size, and then click "Set". YOU HAVE TO CLICK THE SET BUTTON. Do the same to remove it from the drive you don't want it on. ("No paging file".)
You'll then need to reboot and the pagefile will relocate.
I found this issue on ours, it has 24gb ram, so used the same for pagefile!
