I've installed Vista on my 64bit Intel PC and it works just fine, the RC2 candidate did not. But, yesterday, I got a strange problem. I was copying some files from my server to the PC and for some strange kind of reason my wireless network decided to stop working, restartet the router and it worked fine again. But Vista broke down totally, couldn't end the copying session, rdp connection to the server wouldn't work, and finally explorer died, got explorer startet again throug task manager, but when trying to reboot, it just hung in the logging off process. Only thing to do was hitting the power button. Just a little experiense from me.
