Any idea how this works in the Windows world with bitlocker? I hope it's not same vulnerability

I recently changed motherboard on my laptop, had the bitlocker key if not I was told I'll have to reinstall Windows all over again.

Even with the key, one must decrypt and re-encrypt.

That's not true, the unlock key will be regenerated, but the disk contents will not be re-encrypted, because it's encrypted with another immutable key.
