If your machine is still covered by a warranty, always speak with the manufacturer first before doing anything that could potentially void it.For the most part, though, the process is similar enough across machines that you should be able to use the instructions as a guide and, where your computer differs, still identify the equivalent menu or label in your own system. That's because Windows machines vary so much that it's not feasible to cover all the possible ways to enable TPM and Secure Boot across every device. Keep in mind that these instructions are written as broadly as possible.If you are missing the hardware or firmware necessary for Windows 11, the instructions below won't help - you'll need to buy a new device to run the OS. Microsoft confirmed there are four types of problems that might have given you a 'This PC can't run Windows 11' error message if you used its PC Health Check tool.This should help in cases where folks assumed CPU compat issues were TPM related /eZLTZMOdjT- David Weston (DWIZZZLE) June 25, 2021 It now provides more detailed info on requirements not met. We just made updates to the Windows 11 PC Health Check App.

In Russia, TPM use is only allowed with permission from the government. China uses its state-regulated alternative, TCM. TPM-equipped machines generally aren't shipped in countries where western encryption is banned. However, it also allows remote attestation (authorized parties can see when you make certain changes to your computer) and may restrict the kinds of software your machine is allowed to run. An updated and enabled TPM is a strong preventative against firmware attacks, which have risen steadily and drawn Microsoft's attention. TPMs are controversial among security specialists and governments. TPM 2.0 is the most recent version required. Previously, Microsoft required original equipment manufacturers of all models built to run Windows 10 to ensure that the machines were TPM 1.2-capable. A TPM has been a mandatory piece of tech on Windows machines since 2016, so machines older than this may not have the necessary hardware or firmware. Some TPMs are virtual or firmware varieties but, as a chip, a TPM is attached to your motherboard during the build and designed to enhance hardware security during computer startup. TPM microchips are small devices known as secure cryptoprocessors.
