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?
