How to fix "This copy of Windows is not genuine error"


If you have been using Windows for a while one issue you may have encountered is the dreaded “This copy of Windows is not genuine” popup followed by your desktop reverting to a solid black color replacing your wallpaper.

If this message looks familiar then follow along to discover how to remove this message and continue using your computer normally. This problem can arise when your computer is not connected to the internet for an extended period of time or hasn’t been used.

During this time Windows is unable to communicate with Microsoft license servers and triggers a built in feature called Windows genuine advantage which was designed to invalidate illegal or counterfeit copies of Windows.

Despite these intentions from Microsoft the feature can arise randomly  or from the scenarios mentioned above, a more serious concern however is that some Windows updates may not work leaving you without potential security patches and fixes for your system.

Even if you have a legitimate copy of Windows this error can still randomly occur resulting in a rather annoying user experience, follow the steps below to find out how you can rid your system of the error and get your computer back to normal.
