As the resident TFS admin, on occasion I am asked to undo a checkout (usually a lock) that a user has on a certain file. This can be done via the command line using the TF.exe utility's Undo command (see http://msdn.microsoft.com/en-us/library/c72skhw4.aspx), but that's kind of a pain.
Is there a way to undo another user's checkout via the GUI?
