Mike on Windows Config Mgr and Secure Boot

Mike Terrill has 2 blog posts on Windows Configuration Manager and UEFI Secure Boot:

BIOS and Secure Boot State Detection during a Task Sequence
With all of the security issues and malware lately, BIOS to UEFI for Windows 10 deployments is becoming a pretty hot topic (unless you have been living under a rock, UEFI is required for a lot of the advanced security functions in Windows 10). In addition, with the Windows 10 Creators Update, Microsoft has introduced a new utility called MBR2GPT that makes the move to UEFI a non-destructive process. If you have already started deploying Windows 10 UEFI devices, it can be tricky to determine what state these devices are in during a running Task Sequence. The Configuration Manager Team introduced a new class called SMS_Firmware and inventory property called UEFI that helps determine which computers are running in UEFI in Current Branch 1702. This can be used to build queries for targeting and reports, but it would be nice to handle this plus Secure Boot state (and CSM) during a running Task Sequence. We do have the Task Sequence variable called _SMSTSBootUEFI that we will use, but we need to determine the exact configuration in order to execute the correct steps.[…]
