Driver signature enforcement in Windows Vista and later versions requires all kernel-mode drivers to be signed with a digital certificate. Plenty of 3rd party applications that rely on such drivers can no longer function since most software developers are simple individuals and code signing certificate is expensive. Officially, there is only a temporary solution to disable driver signature enforcement (to press F8 during system startup). Driver Signature Enforcement Overrider is a permanent solution to load unsigned kernel-mode drivers by using TESTSIGNING mode with a test-signed digital certificate.
Instructions:
1. Right click on the application and choose 'Run as administrator'.
2. Press on 'Enable Test Mode'.
3. Press on 'Sign a System File' and enter the filename including full path (for example: C:WindowsSystem32driversATITool64.sys) and then reboot.
4. Use this tool to remove the watermark from the desktop.
