Extend Windows 7 's activation period using "Windows Software Licensing Management Tool"

Hi, having not yet the time to go and meet my dear Admins with my legal copy of Windows 7, I had to extend the activation's period. Here's the well known trick that also worked on Windows VISTA :

Click on “Start” > “All Programs” > “Accessories” and then right click on “Command Prompt” and select “Run as Administrator”

slmgr -rearm

It stands for "Software License ManaGeR" and is a VBS Script that adds an extra 30 days (you can do this 3 times).

Once you run that command, wait for a few seconds then you will have a popup "La commande a été exécutée. Redérarez le système pour que les modifications soient prises en compte." (something like "The command has been executed. Restart your system so that the modifications can be taken into account")

After the maximum allowed, you'll have the message :
"Error: 0xC004D307 The maximum allowed number of re-arms has been exceeded. You must re-install the OS before trying to re-arm again"

You have the same thing for Office 2010 :
