Yurako: I don't have a Start Menu under the path suggested. I am surprised that you found one, and that it is blocked. But my installation is heavily customised, so anything is possible!
If we are discussing Windows 7, then my path to the user Start Menu is Users - username - Appdata - Roaming - Microsoft - Windows - Start Menu.
To see App data, you must open the Tools - Folder Options - View - "Show hidden files, Folders etc..."
