I agree with
@rockbottom. NEVER update *anything* just before doing something important! That includes automatic updates as well as manual ones. Turn off all the automatic updating, and then DO UPDATE MANUALLY on a schedule that works for you, that provides enough time to TEST AND TROUBLESHOOT before you have to rely on it again.
In a different environment, I've heard far too many stories of Windows forcing an update and reboot in the middle of a church service, because that's the only time they ever had the lyric projection machine turned on. Same problem, same solution: completely disable the automatic stuff, and then *do* maintain it manually, *outside* of the critical time window.
(Immediately after the last service, perhaps? Or after your recording session? When you're still there and the machine is still on anyway, but the critical time has just ended...)
If you don't take the security patches, then you're gonna get hacked......
But take them on *your* schedule, not someone else's!
