Hiding The Virtual Memory Button in Control Panel, System
You can use this Registry entry to hide the Virtual Memory button on the Performance tab under Control Panel > System. By hiding this button, you can prevent users from changing or disabling the machine’s Virtual Memory setting, which can adversely effect the machine’s performance.
To make this entry, open the Registry Editor (Regedit) and drill down to:
Edit or create the key value “NoVirtMemPage” (String Value) and set the value to “1” (without quotes).
This will hide the Virtual Memory button,
Or set the value to “0” to display the button.
Note: You will need to reboot after making the change in order for it to take effect.
