As a network manager and MSDN subscriber, I have had access to the RC and the RTM from day one. I have been using the RTM since the day of release and as many have said, it’s faster in every way. Shutdown/restart takes about 60 seconds. Less of a resource hog, pretty, easy to use and more convenient, compatible with EVERY GAME AND PROGRAM i have attempted to install and UAC is not a pain. It warns of a couple minor things but that’s good because it gives you a chance to back out of a sometimes quick and rash decision.
Highlighting the taskbar thumbs is awesome and highly effective when having several windows open. 64-bit all the way………..if your processor supports it. Windows 7 is fantastic and Apple knows this as we’ve all seen 10 times the amount of Windows bashing commercials regarding 7 in the past few months. Apple is not without its problems, crashes and viruses……………and uses Intel so powerpc computer is gone.
Windows 7 Home premium is a waste in my opinion. Professional is the way or Ultimate but like a previous commenter said, Ultimate is only different in that you can encrypt the HDD (which is only helpful and applicable with laptops) and multiple languages. Professional has Remote Desktop and that’s necessary when you have a friend that can fix your computer from their own home. Very necessary.
As for those saying “In place upgrade”………….real IT pros NEVER EVER EVER EVER do that. Clean install only. Format your drive, back up files necessary and start fresh. Accept any losses as it’s par for the course with computing.
