Traditionally, you cannot uninstall Microsoft Office service packs without completely uninstalling the Microsoft Office products.
Guess what? Microsoft is releasing the first Service Pack Un-installer for 2007 Microsoft Office suite Service Pack 2 (SP2).
Check out for more information from the following link! And of course, obtain the un-installer as a fall-back plan during your rollout of Office 2007 SP2. 🙂
However, I find that SP2 really solves a lot of issue of Office 2007 especially with the Outlook. 🙂
