Black Desktop Background

first, just to say "Thank You" for those who contributed excellent solutions to this issue I just encountered - not on my system but one I put in for someone else. But have a question and want to compare notes please.

Did any of you who had this "black background" desktop check the Windows Error Logs for a related error?
The system I worked on today is windows 7 professional, activated, etc but it had a few common malwares. After cleaning it up the Desktop was black though the Themes were still invoked. I tried messing with Personalization settings and best I could tell, no AERO scheme will work. Basic [Like Windows 7 Classic] do work. When I checked Error logs [system] there was a related message basically saying that Themes is dependent on a service that was not marked correctly. I could not find/understand what it was telling me and failed to get it going.

Any of you seen the same thing? Everything else on the system looks ok.

Thanks man for the easy fix!

Thanks. It solved my solid black background (wallpaper) problem in my new Windows 10 update.

Hunting for a solution but found an easy one myself that worked for me. Go to Control Panel then to Personalization. I simply had to click on the Basic blue windows background to get that back.
