Move the Public folders on Windows 7
The solution posted by Ivo did not work for me. As Omar originally wrote, the textbox within the location tab was not mutable, and there were no browse or move buttons.
I found the following solution which worked for me:
Close all folder windows.
Open an elevated Command Prompt window by clicking Start, All Programs, Accessories, right-click Command Prompt, and then click Run as administrator.
Click the Start button. Press and hold the CTRL and SHIFT keys, and right-click on an empty area in the Start menu. You’ll see a Popup menu containing the two options namely Exit Explorer and Properties. Choose "Exit Explorer". Your start menu and task bar will disappear.
Switch to the admin Command Prompt window
In the Command Prompt, type explorer.exe and press ENTER. This starts the Shell under elevated privileges.
Now you can open up the original public folders and should have full access to the location tab, including restore, move, and "find target" buttons.
Once you've done moving your public folders, log off and then log back in to return explorer to pre-elevated levels. This is an important security step.

If the administrator account is enabled, simply log in as administrator and you should have full access to the location tab of public folders. The above mentioned solution may not work anyways in this case.
