Hi. . .
Thank you for the user shell folder listing.
Somehow, your Downloads shell folder got changed to Desktop.
Your system:
{374DE290-123F-4565-9164-39C4925E467B} REG_EXPAND_SZ %USERPROFILE%\Desktop
Should be:
{374DE290-123F-4565-9164-39C4925E467B} REG_EXPAND_SZ %USERPROFILE%\Downloads
Create a system restore point.
Go into Regedit - go to -
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
Scroll down/locate {374DE290-123F-4565-9164-39C4925E467B}
Double-click on the icon next to it; paste in %USERPROFILE%\Downloads
As for your lost programs, before doing the above, revert the restore point. Go into System Restore - there s/b a selection to un-do the restore.
Search | type rstrui | select restore point
Regards. . .
