How to Disable Windows Genuine Advantage Verification Tool

By Emilio Alvarez

The Windows Genuine Advantage (WGA) verification tool is a built-in application designed to be a piracy detector that enforces the use of legitimate versions of the Windows operating system. If WGA detects you are running an illegitimate version of the operating system or erroneously registers it as "Not Genuine," it will consistently display the annoying alert: "This copy of Windows is not genuine."To disable this notice and the WGA verification tool altogether, you will need to make changes to your system via the MS-DOS command window.
