The Fall Creator Update Messes up and Locks out the TPM
It looks like that the Fall Creator Update disables or suspends Bitlocker to reboot PCs multiple times during the update. In the end, it messes up with the TPM settings. Once the update is complete, the OS drive is unable to decrypt. The boot Bitlocker screen errors out as too many wrong pin attempts.
Booting a locked out machine with an external OS shows that the TPM LockoutCout is stuck at 32. It's not reducing after 2 hours of healing time. Update has also deleted Recovery Key option for the OS drive. Hitting escape takes the machine to recovery console. Support desk is unable to provide any solutions and asking to format the hard drive. It's a complete mess. When is it going to be fixed?
