ReversibleNote the exact update version or newly installed software, and confirm the prior working state. Expected behavior: unlock the encrypted system with the correct recovery key after a trusted-state change.
Isolate the component boundary
ReversibleIdentify the recovery-key ID and check the owner’s Microsoft/work account records. Uninstall the new software or roll back the update in a controlled test, where the OS supports it. Boundary to separate: legitimate device ownership/key record versus firmware, account and hardware changes.
Correct only the proven cause
ReversibleUse the matching key, restore trusted boot settings or involve the organization administrator. Apply the vendor's fix for the update, or reconfigure the setting the new software changed.
