Microsoft described the issue on its Windows 7 support page: “After installing KB4534310, your desktop wallpaper might display as black when set to Stretch”. Some solutions to this were offered, which involved using a wallpaper option like Fill, Fit, Tile or Centre to avoid the black screen issue.
 
Now, the millions of PC users still running Windows 7 can expect one more patch despite support ending. This will fix the black wallpaper issue when using the ‘Stretch’ option and will be released to all customers running Windows 7 and Windows Server 2008 R2 SP1.
 
Users shouldn’t expect further updates though. For businesses and other organisations, Microsoft does offer an Extended Security Updates license, which costs up to $50 per PC still running the Windows 7 OS.
 
For 50 bucks per PC it is easier and cheaper in my opinion for businesses to upgrade to Windows 10
 

Cool GTX
So very generous of MS to fix something that their recent update broke
 
I've heard more than one Program Manager say they would never hire a programmer from Microsoft

 
 
 
I find it odd that they announce support ending and then magically ' a mistake'  makes all the systems screens go black....???   - Yeah right.
