Vista - How to turn OFF "Test Mode" in Vista x64 Ultimate

Is there any way to turn off "Test Mode" in Vista x64 Ultimate?
Once upon a time I disabled driver signing through bcdedit /set nointegritychecks ON or bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS (don't remember anymore).
Now I would like to enable it back on, but can't.
As suggested; bcdedit -deletevalue loadoption or bcdedit /set nointegritychecks OFF/NO didn't work.

Also atempt to remove only the "test mode" watermark by overwriting user32dll.mui also didn't work. I managed to overwrite the file with changed files in bots system32 and syswow64, but nothing changed.

Can anyone please help?

Hi Estugarda,

Did you do this to turn on driver signing check again?

1. Right click on CMD and click Run as administrator.
2. Type bcdedit.exe /set nointegritychecks ON and press Enter.
3. Restart computer.

You can turn off Test Mode by typing bcdedit /set testsigning off in the elevated command prompt above to.

Yes I think I've tried that too.
I've tried everything what can be found through google.
Another thing worries me now; if I somehow manage to enable driver signing back on and my computer refuses to work because of some unsigned drivers, that I'm not aware of, could I turn driver signing back OFF?
Some people say it is impossible after certain microsoft updates...

Since my system works fine now on "test mode", could I only remove that anoying "test mode" watermark in some way other than described in my first post?

Estugarda,

You can turn off Test Mode by typing bcdedit /set testsigning off in the elevated command prompt above to.

You should be able to turn off driver signing again without being in Test Mode. Type bcdedit.exe /set nointegritychecks off

Thanks Shawn, but...

I know what you are talking about. I've tried typing bcdedit /set testsigning off in command prompt as admin. It didn't work.

I just got an advice on PlanetAMD64 forum to try through editing gpedit.msc. I think it could work that way, but I am concerned about possibility not to be able to turn driver signing off again if necessary. People on PlanetAMD64 say that it is impossible to turn off driver signing after some KBXXXXX update. I don't want to take the risk.
Right now I would be pleased just to remove "Test mode" watermark on my desktop.
Can you, or someone else, help me with that?

Estugarda,

I'm not sure how that method will affect the Test Mode, but it will let you disable the driver signing check with the Ignore option.

Shawn

Well, maybe. Maybe not. However I'll know only if I try it...
I'd rather disable "Test mode" watermark only.
Any ideas how?

Estugarda,

Sorry no. The bcdedit /set testsigning off was the only way that I knew of to turn off Test Mode. Hopefully, the GPEDIT.MSC will do it for you as well.

Shawn

Thank you anyway.

Sorry Shawn (aka brink), bcdedit /set testsigning off line is working afterall. There are so many (real or fake) versions of this online, that I somehow lost the oversight.
