To change your default desktop location and do the following:
- Open the Registry editor (Regedit.exe)
- Browse to the location:
HKCU > Software > Microsoft > Windows > CurrentVersion > Explorer > User Shell Folders.
- In the right window pane select the required value (i.e. Desktop).
- Insert the new location for the folder to be stored.
- Close the registry editor and log off.
When you log back on your Windows 7 folder location such as the desktop will be stored at the new location. You do need to note that any content that was stored in the old location does not move with the change and will need to be moved from the old location to the new location before you will see it again.
