Most "Remove WAT" downloads on the web are bundled with trojans or ransomware.
Under normal circumstances, Windows requires a valid product key to activate the operating system. This process verifies that the software is genuine and not installed on more computers than the license allows. Microsoft implemented "Windows Activation Technologies" (WAT) to check the validity of the operating system. RemoveWAT was designed to disable this technology entirely. Rather than providing a stolen key, the tool modified the operating system's core files to stop the activation checks, effectively tricking Windows into believing it was a fully licensed, genuine copy. remove wat windows 7
