October 2016 Patches Causing Bitlocker Issues

    General discussion

  • There are few reports of users having Bitlocker issues following the October 2016 patches. The issue is that on every reboot, the Bitlocker recovery key is required which is quite disruptive and cumbersome. As a workaround in order to solve this issue, the following steps can be taken:

    On the next reboot and once in Windows, reset Bitlocker by disabling and re-enabling it.

    In admin command prompt:
    manage-bde -protectors c:-disable
    then do the following
    manage-bde -protectors c:-enable

    At this time, I'm not certain on which patch is causing the issue but I wanted to share this info to help.

    MS is pushing first time massive quality updates to W7 and W8.1, so it might be releated to them..

  • There are some reports in a closed IT Pro group on Facebook. I've received some reports of similar issues in my organization. The OSes reported are Windows 7 and Windows 10.

  • In admin command prompt:
    manage-bde -protectors c:-disable
    then do the following
    manage-bde -protectors c:-enable

    Any opinions, should there be a reboot between disabling and enabling Bitlocker?

    I don´t have any problematic computer on my hands right now.

  • I can´t repreduse this failure on Windows 10 with TPM+PIN, have tested multiple machines. Maybe the problem is only around Windows 7?

  • This issue is currently being investigated , Can you share some logs if needed ?

    C:\Windows\Logs\CBS directory and GPreport from few of the affected clients.
