WinXP displays even *.jpg images as wallpapers. Strangely I am unable to set a jpg image as one. When I try to,, I get the error message of 'rundll32 causing an error in mshtml.dll file'. I have no idea what it means. I even tried restoring my system to an earlier state, still the problem remains. Win98 used to have a utility to extract original files from the cab files to replace any altered ones. Is it possible to do this in WinXP Pro? If yes, how should I go about doing it?
