DEP settings on windows 7 do not stick

Reported by: heyricardo Owned by:
Priority: major Component: other
Version: VirtualBox 3.0.12 Keywords: DEP
Cc: Guest type: Windows
Host type: Linux

Description

In order to fix a COM Surrogate error on windows 7 VM, I had to add an exclusion on the list of programs subject to DEP. But whenever I restart the machine the setting is not there, it keeps the old one (enforcing DEP w/o exclusions).

And what makes you think this is a VirtualBox problem? If you are using a 32 bits Windows 7 VM, you must make sure PAE is enabled. (DEP relies on it)

Replying to sandervl73:

DEP is enforced on windows components (so I believe PAE IS already enabled, and it is anyway); also the setting DO work on a physical system. It just do not stick on the guest VM.

Without the VBox.log file of that VM session I can't help you further.

I made the change. Then I had to reboot. Right after rebooting, here is the vbox.log I found.. (sorry for double submission..i got confused with the interface)

PAE is not enabled in the VM settings as the log clearly shows.

Your Celeron CPU doesn't even support PAE actually.
