Last night, I manually installed the update on a six year old desktop PC and also my Toshiba Netbook.
I have to report that while the update took a while to install, it did so successfully on both machines. There are reports that it craps some machines out, but mine can’t be included in those statistics.
I didn’t install the update for new features, by the way. It was purely done to keep them both as current as they can be.
