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?

What would you expect to be the result of this? When a process exits, all memory it allocated is automatically freed. – Oliver Salzburg Mar 10 '13 at 0:00
What'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 Mar 10 '13 at 0:16
@OliverSalzburg and Journeyman Geek: I am a bit worried about live forensics, and am looking for a solution to zero out an area of RAM when a restart would not be ideal. – christiansonk Mar 10 '13 at 0:32

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

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

    %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks

  4. Paste it there & click “Next”.
  5. Give it a name like Clear RAM
  6. 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 – Journeyman Geek Mar 10 '13 at 3:19
