I understand that Microsoft see the large number of vulnerable machines on the internet as a problem thay they are responsible for and the forced update as a necessary solution.
Nevertheless, I dual-boot my laptop and use Windows almost only for presentations. Whenever connections to external devices and other OS shenanigans force me to reboot my machine when I'm in the speaker position and the dreaded forced update cycle begins I swear I'll never touch that ugly OS ever again. And I already developed routine of checking for updates and booting in advance, but somehow this still happens from time time.
I guess there's need to be a special "seriously not now pretty please" button.
