I Vlited myself a Vista x64 SP1 one disc and set Data Execution Prevention to always off. Is there anyway to set if back to default without making a new disc and reinstalling everything?

cmd-> bcdedit.exe/set nx OptOut

thanks

The default DEP setting is OptIn

Run this command under elevated CMD

bcdedit.exe /set nx OptIn

and optin is better becouse...? Nevermind, maybe you have your pc with all the default settings.

Right Click on Computer>Properties>Advanced System Settings>Performance>Settings>Data Execution Prevention>Turn on DEP for essential Windows programs and services only.

Apply and OK.
