I’m sure the patch itself can be fixed, and there will be a workaround to boot up the machine to fix it. My only concern is the BitLocker keys. If the hard drive is encrypted by Windows and assuming no backup for that key has been done, the system admins will have to activate their disaster recovery plans for these devices, and I hope they have that too, but hope isn’t a strategy!
If the keys aren’t backed up, you will be locked out of the system, and as soon as you try to boot into the safe mode to perform that workaround, you will be asked to enter it manually (or if you have it back it up on a USB drive), if you don’t have, or don’t know the key, you will have an encrypted drive with all of your data locked there.
