Reset your Microsoft Office 2003 Serial Number

From time to time I will come across a machine that has a pirated office serial number. Microsoft checks your serial number before allowing you to download updates for Windows, and Office.

You simply need to drill down to this registry key (As always backup your registry before messing with it):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\11.0\Registration\{90110407-6000-11D3-8CFE-0150048383C9}
See the two values: ProductID, and DigitalProductID? Delete them.
Now run launch any office application, and you will be prompted for the new serial number.
