Hi Wendy,
It sounds as though you have Windows 7 Starter. Is that correct?
If so, there is no personalization. However, you can get around this very easily by downloading Oceanis, it's safe, it's free and has been a solution for so many people with the same problem as you.
Here is the link: Oceanis
When you have downloaded it, you will be able to change the desktop background and there is also an optional desktop slide show (shuffle).
Let us know if that solves your problem. If you don't have Windows 7 Starter, then your problem will have to be resolved another way. Please come back and let us know if that is the case. 🙂

My Device Manager is disabled
Well I think not only your device manager is disabled even your task manager is also disabled and you can’t view hidden files. You infected by a Worm/Trojan virus which automatically disabled registry, and windows system files upon infection. To fix this please download the latest version of malwarebytes from here. Also download ccleaner
If you can’t download on your PC then try another PC with Internet connection and download the 2 files and save it in your USB.
Note: Don’t place it in a folder just send the exe file directly to your USB. Now install Malwarebytes, and perform a quick scan. Restart your PC afterwards. Now install ccleaner and perform a disk cleanup and also perform a registry check and fix. Restart your PC after.
