Is there a Windows utility to delete contents of RAM left by an application?

Ideally, this utility would know where in physical RAM an application was and completely clear its contents when it's closed. Does anyone know of such a utility?

4What would you expect to be the result of this? When a process exits, all memory it allocated is automatically freed. – Der Hochstapler – 2013-03-10T00:00:49.543

1What's the possible threat here? If you're worried about live forensics, unplugging the system does usually work, and very often people do it anyway. Considering the window for a freeze attack is tiny, adding a physical lock to a case and pulling the cord should utterly negate most forms of memory acquisition, live or offline. – Journeyman Geek – 2013-03-10T00:16:32.937

Windows already zeros all free Memory before it is used again (zero page thread):

Right click anywhere on your desktop.
Point over “New”, then select “Shortcut”.
Copy the below line (as it is):

%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
Paste it there & click “Next”.
Give it a name like Clear RAM
That’s it, run it every time your computer goes slow.

Thats a bit of an urban myth - lifehacker points at microsoft's documentation, which disagrees with this
