Twice now I've been stuck during a power failure with just a few minutes of battery in my UPS, and when I try to shutdown Windows, it goes into its "installing updates" thing. There's no way around it, and of course losing power during this is probably the most dangerous thing imaginable. Luckily, I escaped with my life on both occasions.
When I use to dual boot windows I never updated and always "restarted" by just holding the power button down (stupid, yes I know, but it's the only way to reboot it as fast as I'm used to when booted into Linux). Never installed updates and it always worked fine, until I wanted to install updates, then everything broke. I assume this was just caused by waiting too long between updates. My solution was to delete the windows partition and just use a VM.
