You are not going to like this, I mean no disrespect.
First, Win 7 is nothing more than cleaned up Vista, which never needed any cleanup.
Actually, it is something less than Vista: Win 7 has in the U.S. had an advertizing campaign emphasizing "Simple". What it should have said is more Apply O/S like. WMP12 lost Advanced Tag Editor. One must now change a config to see file extensions, hidden and system files.
The biggest changes are actually in Office 2010. Outlook, previously highly configurabel, has lost is menu bar and practically all of its config options.
Everything at MSFT is becoming SIMPLER, more Maclike.
Now, my only experience with Mac software are with Safari and iTunes. I dropped both because I could not configure them to act in the way I wanted. I had to use them as granted by Cupertino or go elsewhere. I went elsewhere.
I am an Apple stockholder, I love Apple, just not for me, and not for my Windows computers, even if MSFT wants to act like Apple.
I now have 5 (count'em) Win 7 machines. If it was up to me and if it had support beyond 2014, I would put Vista on each adn every one of them. And Office 2007 and WMP11.
