    USBs encrypted with BitLocker To Go causes Windows 10 machines to hang


    Hi

    Months ago we configured BitLocker To Go (BTG) group policies which worked flawlessly for 1000+ users until around 13-Dec when Windows Defender was updated from version 4.14.17639.18041-0 to 4.18.1812.3-0. Since then when a BTG USB drive is inserted it causes Windows 10 v1803 (OS Build 17134.523) machines to hang for 10 minutes before finally prompting the user for the BTG password which then allows access to the drive contents. This issue does not affect Windows 7 machines.

    we've tested temporarily disabling Windows Defender fixes the issue but this is far for ideal and only for troubleshooting purposes obviously:-
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\DisableAntiSpyware set it to 1 to disable Windows Defender

    Also rolling back this update to the Inbox CAMP version by running the following command fixes it too but also far from ideal:
    "%programfiles%\Windows Defender\MpCmdRun.exe" -resetplatform
    C:\Program Files\Windows Defender\MsMpEng.exe (v4.13.17134.320)

    Is there a proper fix for this issue please?

    Best regards
    Scott
