about 100 mph , because my car ' s shit and doesn ' t go faster than that . <| sep |> Try to check this registry key on the target computer to see if it ' s getting filled ? H K C U S o f t w a r e M i c r o s o f t W i n d o w s C u r r e n t V e r s i o n P o liciesSystemWallpaperAlso Simple put using a UNC path puts a lot of stress on network as it has to download file every time the wallpaper is loaded .
