If you install a hacked or illegal copy of Windows 7, you receive an error that the operating system functions are disabled, because it is not a "genuine copy." To fix this error, you must re-enter a valid, legal product code. Windows 7 has an interface that lets you re-enter a license key. This is beneficial if you receive the "not genuine" error message or you want to upgrade your license for the operating system.
