I have Windows XP and lately I get this issue were I have any wallpaper and after a few minutes the wallpaper gets removed and all I see is black screen that I set it as a background for that theme. Is under the Windows XP (Modified). I tried changing the theme to a different one, for example going to My Current theme or Windows XP but still after 5 minutes the wallpaper changes back to the default one.
Also I noticed that now I have the Windows warning message letting me know that I have counterfeit version for windows printed on my screen and I can't get that removed. I was able to fix the issue for a few days. What I did is that I just went and search for a wallpaper in Google and then from the website I just right clicked on the image and selected as a wallpaper, that fixed it for at least 3 days, but then it started over again.
Any ideas on how to fix this?
