I was trying to turn on the DEP in the systhem console (wich i opened as administrator) with bcdedit.exe /set {current} nx AlwaysOn and i got this error
PS C:\WINDOWS\system32> bcdedit.exe /set {current} nx AlwaysOn (next few lines are translated from russian to english)
Invalid installation command.
For help, type "bcdedit /?" At the command prompt.
The parameter is invalid.
PS C:\WINDOWS\system32>
