Kill WGA/OGA

1. Close all Office programs
2. Open command (you know or don’t mess with this) – do it as ADMIN! Windows button + R and enter “cmd”, select “run” from the menu or one of the other ways to do the same thing.
3. Type the following (or copy it from here): MsiExec.exe /X{B2544A03-10D0-4E5E-BA69-0362FFC20D18} – press enter
4. Go to Windows update (Select it from menu or from Internet Explorer, which by the way you shouldn’t even have a short-cut available to!) and search for updates
5. KB949810 will appear – right click and select “Hide update”
6. DONE – you have pwned it!

I tried it in three cases and worked flawlessly on all three. What you do is simply an uninstall of the WGA component, and block it from being part of Windows Update.
