When enabling Bitlocker on a Windows 10 device you may have encountered the following error “A problem occured during BitLocker setup. You may need to restart BitLocker setup to continue. Error Code: 0x80042574.
To simply fix this issue you just need to log on as the administrator and run Bitlocker again. At this point I am not quite sure what causes the issue. It is very rare and only happened on a Surface Pro 4 connected to our domain.
