I upgraded to Win7rc as fast as I could from the beta and pretty much all the problems I had on the beta are gone! I’ve never experienced a beta OS as stable as this one, it’s nothing short of impressive.
Hangs on reboot/shutdown are gone.
Annoying stuttering sound probs are gone.
File copy probs are gone.
Screen update probs gone.
I’m running 64-bit on a DELL Precision M4400 and the funny thing is that think I’ve not installed any extra drivers except for the touchpad and the initial network drivers, and it runs like a charm. It was a nightmare to get it working properly on 64-bit Vista, even when it came pre-installed with it from DELL! (Shame on you DELL to ship a box that doesn’t even run properly on the pre-installed software!!)
I will have to install the extra software to get the built-in 3G mobile network running and that was kind of tricky on the beta, and the finger-print reader I’m not even going to bother with.
