Everything I've read says that you'll have to re-install all your programs. The upgrade to Win 8 Pro will only transfer/migrate applications from Windows 7 Home & Home Premium. Even Win 7 Pro and Ultimate users have to re-install applications. All the upgrade process does for other operating system versions is transfer your settings and personal data files, or just your data. Or it will alway permit a clean install where nothing is transferred/everything must be re-installed, including setting and data.
I'm moving from Win 7 Pro to Win 8 Pro, and so far everything re-installs without a problem, but I'm only about halfway done and am probably going to take the opportunity to she'd some of the old software, but so far I haven't found anything that would work in Win 7 that wouldn't work in Win 8.
YIKES! I was so pleased at how smooth the transition was from Vista to Windows 8 Pro. Look at all these new and free apps! Life is good!
Wait! Where is my MS Office Suite, Quicken, Tax Programs, etc?? Help!
