Do you feel uncomfortable sharing documents with other users? Would you like to have greater control over document sharing on your network or PC? You may want to delete the Shared Documents folder on your machine.
Although deleting the Shared Documents folder on your machine won’t fully prevent users on either your network or your machine from sharing documents, doing so may deter those who are less than determined.
If you would like to delete your Shared Documents folder, you will have to edit your registry. This particular tweak will work on Windows XP based computers. Remember, you should always create a back-up prior to making any changes to your registry. Changes are irreversible unless you have a back-up file of your registry.
Here are the steps for deleting the Shared Documents folder:
1. Click Start and go to Run. Now enter regedit.
2. Go to HKEY_LOCAL_MACHINE. This can be found on the left side.
3. Expand HKEY_LOCAL_MACHINE by clicking on the little cross to the left.
4. Look for the Software folder. Once you find the folder, expand it.
5. Now look for the Microsoft folder. Expand this to get to the Windows folder.
6. Expand Windows and look for CurrentVersion.
7. Go to Explorer and expand.
8. Under Explorer, look for MyComputer.
9. Now look for NameSpace. Expand this folder to get to DelegateFolders.
10. Expand DelegateFolders. Look for {59031a47-3f72-44a7-89c5-5595fe6b30ee}. Be careful. Long numbers and letters may be confusing. Always double check that you have selected the correct key.
11. Right click on {59031a47-3f72-44a7-89c5-5595fe6b30ee}. Select Delete.
12. Exit the Registry and reboot.
Again, this process does not fully prevent the sharing of files, folders and documents.  Determined users will always find ways to share files through the internet or some other means. However, doing this may act as a deterrent for users who are not as determined.
