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.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\explorer\FolderDescriptions
Merged into my pc and voilà !!
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.live.com/self.aspx/Public/Folder%5E_fix%5E_win7%5E_x64/FolderDescriptions.rar
This is for Win7 x64. Use it at your own risk.
