Hello! When i upgraded Windows 7 to final RTM from yeah.. The first RTM leak, our electricity went away and the computer shut down, started it up and everything seemed fine etc. and restarted the upgrade. Do anyone think that this power shutdown caused any harm to the OS? As it was on the second point where it gathered program information etc. when the shutdown happened, so it hadn't begun installing the files it copied on the first point. So far everything seems to work ok, but wanna know for sure.
