If you have a Surface 4 or Surface Book (also any Intel Skylake based PC) with Windows 10 and now run into a BSOD Bootloop (with SYSTEM_THREAD_EXCEPTION_NOT_HANDLED)? Do you have Avast installed? Uninstall it to resolve that Problem. Boot into the Recovery Mode –> Troubleshoot –> Advanced Options –> Startup Settings –> Restart –> Press 5 –> and uninstall Avast. After a Reboot everything should be fine.
PS: If you linked your Microsoft Account with Windows 10, did you know that Microsoft automaticly saves your Bitlocker Recovery Key to OneDrive?
