Cannot change desktop background in Windows 7 Home Premium

kramersan.

I have an Acer 7736Z-4015 laptop with windows 7 premium I just bought a week ago and it has the Acer blue background which I cannot change on the primary administrator account.  I can change any other account even if I make a new account administrator.  What did was to set folder to show hidden files and go to the following folder:  C:/users/username/AppData/Roaming/Microsoft/Windows/Themes.  I noted the Acer blue wallpaper Jpg was there called TranscodedWallpaper.jpg was there.  I deleted that file and rebooted the computer and low and behold the background was changeable.  Of course the "username" is the name of the primary account which is giving the problem.  I traced this by surfing regedit and found this path in a line by searching for backgound and wallpaper.  I don'e like to play with regedit as it can be dangerous to the system but if you don't change anything you can look away.  Hope this helps.

You are the daddy.  After pulling my hair out for weeks trying to figure out the issue I followed your advice and saw my own previous background saved under that TranscodedWallpaper.jpg in the file you suggest.  Following your direction I deleted the file and it works!

Many many thanks!
