HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies

Select the "Explorer" folder.

Go to *Edit*, *New*, then "DWORD Value".

Name the new value "NoSharedDocuments".

Double click the new value and in the Edit DWORD Value dialog box,
change the value data field to "1".

Reboot your computer for the change take effect.

Bye bye Shared Documents folder.

*Windows XP Tip of the Day*

*Tip #593: Get Rid of Shared Documents*

New to Windows XP is a "Shared Documents" folder that appears in My
Computer. This is really just a pointer to another area on disk. You
can keep this from appearing by deleting the following subkey from the
Registry:

*Hive*: HKEY_LOCAL_MACHINE
*Key*: SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\My
Computer\NameSpace\DelegateFolders
*Subkey:* {59031a47-3f72- 44a7-89c5-5595fe6b30ee}

Delete the whole Subkey and all that it contains. You may wish to
right-click this subkey and export it before deleting it, just to be
safe. This also will prevent the current users "My Documents" from
showing up in the same area of My Computer.
