Sort of. Sometimes it goes wrong. I've seen a primary SQL Server go down because WUA took up enough CPU and interrupts to stop the cluster service health pings leading to a BSOD. This happened outside any schedule.
- smileybarry 4y agoGuessing this was in the XP-2003 era if you mentioned WUA? Windows Update had a couple rewrites in Windows 7 & Windows 8.1 to solve the old "checking for updates takes too much CPU % if you have X+ updates installed". It's dramatically better now.
- iasay 4y agoThis was last year on windows server 2019. I say WUA. I don’t know what the current version of it is called. There are still problems.
- smileybarry 4y agoAh, I see. I just remember WUA from that one EXE people ran on Windows XP to manually check for updates.
