Yeah, unless you dual boot when I get stuck for 20mins+, before Windows decides to restart and then goes to "Restoring a previous installation" (or whatever the wording is..) and then I've wasted enough time and just carry on. Que next time I need to boot into Windows and I get to do the same shit again.. Until one time it just actually completes the update.

Oh, and I've been gaming numerous times (when the toast notification is hidden so I don't see it and click it) and then bam, my PC decides to reboot itself.
