How to remove watermark from a Windows 7 PC? It appears after installing SP1 for Windows 7.

 

The Watermark could indicate that you are running a Beta version of SP1. If that’s the case, You’ll need to uninstall it and then install the final version of SP1.

If you have the most recent version of SP1, that could also indicate that you are running a bootleg version of Windows. If you’ve got a bootleg version of Windows, get a genuine one.

If you know that your version of Windows is genuine, this might be caused by the test signaling mode being activated on your computer.

This could be the result of an application whose drivers are not digitally signed by Microsoft.
