Hmm, ok. Could you right click on each of the
HideDesktopIcons keys in the left pane of the registry (regedit.exe) at the locations below, click on
Export, save to your desktop, and
upload them here? I'll be happy to take a look at them to see if I may be able to spot what may be causing this for you.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons
I also updated the REG files in the tutorial to include these locations as well if you would like to download and try them again.
