*If your computer is part of a Workgroup, you will notice that a Shared Documents folder appears in My Computer. This folder lets you share files with multiple users easily. If you want to remove this folder you can:
1. Start the Registry Editor
2. Go to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer \
3. Right-click an empty space in the right pane and select New > DWORD Value
4. Name the new value NoSharedDocuments
5. Double-click this new value, and enter 1 as its Value data
6. Close the registry editor
7. Log off, or restart Windows for the changes to take effect
To reverse this process, change the Value data to 0, or delete the NoSharedDocuments Value.*

Var dock försiktig när du pillar i registret, skapa därför en återställningstid/datum innan om du skulle ångra eller om det går fel. Återställning (klassiskt läge) hittar du i kontrollpanelen.
