Yes, my computer just rebooted and installed software right in the middle of what I was doing with no warning at all.
It was a sizable update that took quite a while and several reboots and countdowns i.e. 30% don't turn off your computer.
Now I'm back in and I have a message that it need to reboot again.
I might as well go ahead and do it, so far my sound is still working so I'm keeping my fingers crosses that it finally got the message to not update my device drivers.
While I was writing this CCleaner just popped up an alert that I had 1.5 Gigabytes of junk to be removed so the update moved a lot of stuff to the junk category.
I've got to close Chrome to run CCleaner then I'll reboot.
