So, I rebooted my Windows laptop after some update, and was greeted by this surprise!
I guess lucky for me I had the machine tied to a Microsoft account which in turn had the key backed up. After some tedious typing later and I was back in business.
I guess this was the culprit?
BitLocker was so transparently well working I didn’t even know it was even running. Got to give it that much credit. And if anything, probably should just give up and run it everywhere.
…not that automatic bitlocker does much except occasionally cause actual data loss
it’s TPM-only bitlocker. need i say more? https://github.com/Wack0/bitlocker-attacks
