Office Preview
I was glancing over the comments and noticed that someone was having an issue with the Office 2013. I am not sure this is any help but:
I installed Win 8 RC and Office 2013 seems to live well along side Office 2010 Pro using the 8 - RC. All my office icons look like Office 2013's but if I open Office 2013 I can load all my office 2010 things fine. I haven't tried to save in Office 2013 format then try to open them in 2010 (Word) but I was even able to build a dummy Excel worksheet in 2013 and it was readable and editable using 2010. I haven't tried any Macros yet. Not sure how things work on my Win 7 Pro, haven't tried it yet.
The only thing that broke on Win 8 - RC was a couple of computer games that I don't play much everything else seem to work fine.
