As a small prank on one of my coworkers I created a group policy object that forced a specific wallpaper (Desktop Background) on her profile whenever she logs in. Laughs were had by all. I deleted the GPO and expected her wallpaper to return to normal. Unfortunately, it did not. Now she is unable to change her wallpaper. When she right-clicks on the desktop and goes to "Personalize" (using Win10) there is a message that her background settings are controlled by the system administrator (Me).
[sheepish] Sooo...Ummm.... How do I undo my prank and allow her to change her own wallpaper again? [/sheepish]
