How to turn on Intel PTT

Post by twistedddx »

In anticipation for Windows 11 I was keen to enable TPM 2.0.

Microsoft list J4115 as supported for Windows 11. J4105 is also listed.
https://docs.microsoft.com/en-us/window ... processors

But I can't find a PTT setting in the BIOS.

Have I miss it or is the BIOS missing this setting?
I believe this would also allow features in Windows 10 like Bitlocker.

We will try installing Windows 11 once they release a trial OS image and look into the BIOS source code.

Current windows 11 builds do not appear to enforce all security requirements that Microsoft say the final release will enforce.
Simply installing current test builds will not be helpful for if the bios has the required features.

To test TPM you can run tpm.msc in Windows 10.
This will show if Tpm is available.
Windows 11 is just proposed to enforce security requirements that were optional in Windows 10.
Tpm, secure boot, mbec are all used in Windows 10 automatically if the hardware offers it.
Microsoft has been suggesting all machines since 2017 should have these features.

Other required security features can be checked in windows settings->device security area. It needs to show secure boot and core isolation->memory integrity to be available.

Windows 11 will become available for the low-life we are during Q1 2022.

If you do not want to become beta-tester of the first production release, you will want to wait 6 months / 1 year to let Microsoft fix the teething issues.

By that time who knows what security policies Microsoft will enforce for Windows 11.

Last but not least, Windows 10 EOL is Oct 2025.

CONCLUSION: you should care about enabling INTEL PTT starting Q4 2022 at the earliest.

In the mean time, if you share your printer with Windows on a not fully secure network, just stop: https://msrc.microsoft.com/update-guide ... 2021-34527

Microsoft have been suggesting that Windows 10 should have had TPM enabled for many years now to increase security.
It becoming a requirement in Windows 11 is what has brought attention to the lack of the feature in DIY equipment.
Dell, HP, Toshiba, IBM etc have had these enabled and in use on all their Windows 10 machines for a very long time.
Everyone was supposed to have these enabled already.

I've been able to get PTT/fTPM working on my ODROID-H2 Rev. B board (J4105) w/ GLK-SF 1.22 BIOS ROM; see my post for more details: viewtopic.php?f=168&t=43166
