Hi Guys

Please let me know how to disable DEP temporarily in Windows 8:

I tried the below but did not work:

C:\bcdedit /set {current} nx Always Off

Then I would like to set it back to normal:

C:\bcdedit /set {current} nx OptOut

When I try, the following message appears:
"An error has occurred setting the element data. The value is protected by secure boot policy and can not be modified or deleted".
