I'd like to add that apparently a first "critical" update was released yesterday. The kind witch the Automatic Updates picks up. Few findings:
Don't know what settings my friend used, but when he turned of his comp, the shutdown screen (the one with stand by, turn off and restart buttons) had some text added to the bottom part. When he clicked turn off, the computer started to install the update. Where one normally has the "logging off" and "windows is shutting down", was a new screen which said something like "don't power off computer - updates are being installed".
On my comp, I have chosen to manually accept the download and installation. I did start the download yesterday, and apparently it took about 30 hours to download. Or at least that was the difference between starting of the download and Windows notifying about installation possibility. I even managed to put my computer to stand by during the night.
Now, for the irritating part. When I had installed the update, it popped up a window with "restart now/restart later" options. I chose later, as I was still doing something. After ten minutes, and what happens? The same window popped up from the tray. And after that every ten minutes. After three times I had to reboot, I just couldn't stand it popping up every now and then...
Cheers,
Jan
