Microsoft acknowledges KB4534310 Update causes Windows 7 desktop wallpaper to display as black
Microsoft has recently acknowledged that the KB4534310 update caused the Windows 7 system wallpaper to be replaced by a black screen.
In fact, before Microsoft acknowledged, many users on Reddit and Microsoft support forums reported that the Windows 7 desktop wallpaper display as black. This problem occurred on a large number of devices causing Windows 7 users to be unable to change the wallpaper.
In the latest support document, Microsoft acknowledges that the problem does exist and states
“After installing KB4534310, your desktop wallpaper might display as black when set to Stretch.”
The temporary solution is to set the custom image to something other than “stretch”, such as “Fill”, “Fit”, “Tile” or “Center”, or choose a custom wallpaper that matches the desktop resolution. Microsoft is “working on a resolution and will provide an update in an upcoming release, which will be released to all customers running Windows 7 and Windows Server 2008 R2 SP1.“
