Remove The Shared Documents Folders From My Computer
One of the most annoying things about the new Windows XP user interface is that Microsoft saw fit to provide links to all of the Shared Documents folders on your system, right at the top of the My Computer window. I can't imagine why this would be the default, even in a shared PC environment at home, but what's even more annoying is that you cannot change this behavior through the shell: Those icons are stuck there and you have to live with it.
Until now, that is.
Simply fire up the Registry Editor and navigate to the following key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ My Computer \ NameSpace \ DelegateFolders
You'll see a sub-key named {59031a47-3f72-44a7-89c5-5595fe6b30ee}. If you delete this, all of the Shared Documents folders (which are normally under the group called "Other Files Stored on This Computer") will be gone.
You do not need to reboot your system to see the change.
Note : Try at your own risk, if your not sure what your doing simply leave it. Just be careful on editing your registry if you are not sure on what you are doing, always keep a backup...
