what happens when you select a new background through display properties? and then apply it.

 

I can't

The area where you can select backgrounds is faded out, and you can't select anything from it.

 

sounds like a spysherrif attack. I know you don't want to download any programs so not much I can really do for you. maybe somebody else has a way without using additional software.

I have 2 suggestions on what it might be, but can't say for sure without seeing logs.

1) Right click My computer and select manage
2) click on the + next to services and applications
3) click on services
4) Select Standard View
5) Scroll down a bit to themes service
6) Doubble click themes service, under general make sure the startup type is
automatic .
7) Select start if the service is not started yet.
8)If it is already started. select stop and select start again.


Option 2 if the above doesn't work:
Click On start>Run> type Regedit

Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

On the right side of the screen, look for an entry called "Wallpaper.htm". Delete it.

 

Thank you!

Thanks a million! Blind Dragon, you're a life saver!
