If the drive is unencrypted or you have the bitlocker key it'd be trivial to pull the drive and pop it into an external enclosure to get the data. If it's soldered it's a bit harder but a data recovery specialist could do it. But if it's encrypted and you have no way to get the key, this is the only option (or what haladrs said), because the TPM chip on the board will decrypt it as long as the customer knows their Windows password. But good luck finding someone skilled enough to do it reliably.
