When reading comprehension is limited to the title.
MS mislabeled the update
Heimdal (apparently a patchmanagement) auto-installed the falsely labeled update.
If OP (this was reported by a Redditor on r/sysadmin) and their company is unable to properly set grace periods for windows updates I can't help them either.
IMHO you are supposed to manually review and release updates either on a WSUS or the management interface of your patching solution.
Not just "Hehe, auto install and see what happens".
And if you do that shit, set a timeout for 14 days at least for uncritical rated updates.
