I booted back into Vista on my desktop yesterday because it is the Ultimate version and I needed to run Virtual PC 2007, which won't run on Vista Home on my laptop. Not surprisingly after being dormant for about a month, the OS choked and on the first boot up nothing worked, including my mouse (it froze on almost every icon). I tried again and the OS came back -- I did my work (amazingly Virtual PC worked nicely) and then I figured what the heck, reward the OS with an update and its Service Pack. I got into Windows Update, saw the updates ready to download (all 398 megabytes worth) and left it alone. Several hours later I got this dialog box.
I returned to the site and tried the update again. Twelve hours later this window was still opening. How long does it take to 'prepare' to install updates. And were they ever downloaded?
The problem with Vista is it's a full time job. So I rebooted back to Windows XP. Let the sucker hibernate for another month til I need it again.
