Windows remove items pinned to start menu

Go to the Registry editor (Start | Run | regedit ). Navigate to the key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StartPage. Look in the right-hand pane for a value named Favorites. This binary value defines your pinned Start menu items. You can't edit it, but you can get rid of it and start fresh. Right-click it, choose Rename, and name it something like Favorites_not. Reboot the computer.
Your Start menu now has no user-defined items pinned to it, only the Windows-supplied Internet and e-mail items. When you pin your current favorites, Windows will re-create the Favorites value in the Registry.
