How To Fix The Black Wallpaper Issue Affecting Windows 7 PCs
Unfortunately, it's not yet clear if Microsoft will fix the issue, since it is no longer supporting Windows 7. We hope it does, because it's a bad look to break something with a final update and then essentially tell users, 'Too bad!'.
Fortunately, there are a couple of workarounds. One is to uninstall the KB4534310 update, though we don't suggest going that route. The other is a clever trick outlined by BleepingComputer. Since the stretch option is borked right now, you can take a screenshot of of your desktop with the image stretched out, and then use that resulting image as your background without the stretch option enabled.
It's a bit of a hassle, because you need to have a clean desktop. To do this, follow these steps...
- Go into the Desktop Background settings and select the Fill option to restore your custom image, then select Stretch again. It will stretch the image as normal until your reboot your PC, at which point it is replaced by a black wallpaper. So don't reboot after doing this. Save the changes.
- Right-click on your desktop, select View, uncheck Show Desktop icons, and select Show Desktop Gadgets.
- Exit all windows and hit the Print Screen key to take a screenshot. Using your image editing program of choice (MS Paint, Photoshop, GIMP, or whatever), save your screenshot.
- Go into the Desktop Background settings and use your saved image as the new background. In the position setting, select Center. You can now safely reboot your PC without having the background revert to a black wallpaper.
- Right-click on your desktop, select View, and re-enable Show Desktop icons.
It's a bit annoying to go through all of that, but once you do, Windows 7 will properly display your background. Alternatively, you can wait and see if Microsoft fixes the issue on its own.
