Plain Blue Desktop cannot change

[Guest]

I got on my computer today and my wallpaper on my dektop was blue. I tried
to change it but my computer won't let me change it. I went to my control
panel, went to appearances and themes, and change computer's desktop
background and my backgrounds are greyed out and I cannot click on anything.
Please help. Do I have a virus??

Hi,

Try this:

Copy the text below between the dotted lines, but not the dotted lines
themselves. Open Notepad and paste it in. Save the result in a suitable
location as "background.reg" {without the quotes} - making sure that
the default .txt extension doesn't appear in the file name.
Double-click on the saved .reg file to merge the contents.
Restart.
