Follow these steps:
1. Create a folder you want to have "Shared Documents" point to. It can be anywhere on your system. A suggestion would be: "My Network Folders" located on a seperate drive dedicated for sharing if available.
2. Rename "Shared Documents" in C:\Documents and Settings\All Users to the name you want to appear in "My Computer" and "Other Places" It must be the same name as the Folder you created in Step 1.
3 Open regedit
4 Go to : My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
5 Edit the value of "Common Documents" to the path of the folder you created in Step 1
6 Go to : My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
7 Edit the value of "Common Documents" to the path of the folder you created in Step 1
8 YOU MUST REBOOT IMMEDIATELY AFTER CLOSING REGEDIT FOR SETTINGS TO TAKE EFFECT.
Thats it! Enjoy this tweak and finally make use of the "Shared Documents" Icon [Now Personalized] in "My Computer" for quick access to shared Home Networking Files.
