Dear JohnGreenleaf,
Glad to see you in Microsoft Community.
May I ask when did this problem start? I currently have two thoughts:
- This is a bug in the preview experience version.
- This is caused by using dual systems on the same device.
Regarding the first possibility.
If the issue didn't exist before upgrade to 25193, it's most likely specific to the current version. I will keep an eye out to see if anyone else posts a related thread in the near future. If this issue is raised multiple times, then I will send a feedback on this issue in order to resolve it.
Regarding the second possibility.
Several conditions need to be met for device security.
- TPM 2.0 (also known as Secure Processor)
- Secure boot is enabled
- DEP
- UEFI MAT
Your hardware undoubtedly meets these conditions, so I wonder if there might be a hardware that is exclusive to the regular version of the system. There is no preview experience version security information in this hardware. This question is obviously more esoteric, and I can't try to extract that information for you.
But you can check whether you can see these settings in the Preview Experience system.
TPM: Press Win+X, select and open Device Manager - Security Devices - Trusted Platform Module 2.0
Secure Boot: Press Win+S, type and search for "msinfo32" and enter - System Summary - On the right side of the screen, look for "BIOS Mode" and "Secure Boot Status"
If there is anything not clear, please do not hesitate to let me know.
