However, the default background is part of the Windows.UI.Logon.pri file within the operating system, and changing the image in the PRI file allows you add your own custom image, that way you don’t have to look at as solid color or the default image every day. In my previous tutorial we went through the instructions to remove the logon screen default background in Windows 10, but many people may also be looking to change the default logon screen for a custom background instead of using a solid color to fill the screen.Ĭhanging the background is a little more challenging, while you can easily change the registry to remove the default logon screen image, Microsoft doesn’t offer a direct registry key that you can modify to add your own custom image.
