I finally got it.
I used the same solution for the similar issue in Windows Vista. Once i got to my company laptop, i exported this 2 registry keys.
Merged into my pc and voilą !!
The 'shell' command also works again (ex: shell: personal brings up the account folder)
I uploaded the reg file and you can get it here http://cid-fb5a28bc4a1cc9b6.skydrive...scriptions.rar
This is for Windows 7 x64. Use it at your own risk.
