I've used FTM 2006 through several generations of computers. For me its worked on Xp, Vista, and Windows 7. As the number of individuals in the tree has increased, certain kinds of reports have gradually stopped working, but I think that's more a problem with memory than with the operating system.
A few years ago when I had a Vista computer, FTM 2006 stopped working for a few months, but other genealogy programs, such as Legacy worked. It turned out that I had a virus on my computer. Once it was fixed, FTM 2006 went back to working great.
