hi all, I have disable code signing with GPO, but there is a warn message from code signing. you see regedit result that GPO works. Why come code signing message? Chris

Hi, This should be normal. It warns you that the code signing is disabled. For Microsoft Windows Vista and later versions of the Windows family of operating systems, kernel-mode software must have a digital signature.
