Shop-safe BitLocker workflow (NLCRC original).
Before motherboard / TPM work
- Suspend BitLocker or decrypt when you will replace the board, clear TPM, or flash BIOS.
- Capture the 48-digit recovery key from the Microsoft account, AD/Entra, or printed sheet.
If Windows asks for recovery
- Enter the key once, then suspend protection before further hardware changes.
- manage-bde -status (elevated) shows protectors and percentage encrypted.
After repair
- Confirm TPM is present in UEFI.
- Resume BitLocker only when the platform is stable and the customer wants encryption on.
Never “just clear TPM” on a customer machine without a recovery plan.
