After upgrading from Windows 10 Creators Update 1 (15063) to the latest fast ring build there was a few problems. Perhaps the most obvious is that after pausing Bitlocker for the upgrade, I have not been able to re-enable it. I am working on this problem right now, and I will update once it is solved.
When trying to enable Bitlocker The error is Element Not FOund. Currently using powershell to try to work on a solution, as the TPM is ready and functional.
Unfortunately I have had to completely wipeout this computer and reinstall the Fall Creators Update version 1709 because I could not solve the problem, but it was due to no recovery partition I think maybe.
