I completed the install of Win 7 yesterday with great results. Today, I finished installing all of the programs that I use on a regular basis, including Office 2007 (Student/Home). Following the install, the program sent me to the web to look for updates and I came across Service Package 2 for Office and choose to download and install it. Following the process, my system became extremely unstable and began to crash repeatidly.
I have just finished my second install of Win 7 and am currently reinstalling the support drivers. I wanted to provide this warning to all. I am not sure what caused the instability - but at this point, I am assuming that it was the Service Package and not Office itself.
I plan on re-installing Office later tonight without the Service Pack update. I will report on its stability after this is done.
