That's one other thing found with 8 is that so far there isn't any option to perform any type of repair install on Windows if you want to save a present installation and just see system files refreshed. The PC Refresh option wipes everything on 8!
At least with 7 you run the installer while booted in Windows and select the upgrade option to install over the existing 7 install while keeping the programs as well as your files and folders intact less the need to reinstall some device drivers.
Essentially 8 amounts to an updated core of a desktop edition while MS stripped things out like the Media Center, dvd playback support in WMP, and simply slapped the Windows RT for Surface Tablets main gui on. The gui or Metro(Modern) was designed with Tablets and swipe touchscreens in mind but is awkward when applied to any desktop release!
With a large amount invested in softwares that run well on 7 you will be in for a disappointment when a few or even several may not run on 8. Just another to mention here. This would be due mostly to compatibility issues often seen when going from one version to a newer version of Windows.
Ironically the 32bit 7 saw far more XP drivers even run as well as old XP programs that would not on the 32bit Vista for the same reason. The backward compatibility factor saw a large improvement in 7 and lost again in 8 it seems.
(And you wonder why MS had to drop the prices way down for 8 with all that going against it?)
