TPM : How to activate TPM so you can update your PC Windows 11
Windows 11 is currently available as a free update to Windows 10 users. However, you may not be able to update your PC if it does not meet the Microsoft system requirements. One such requirement is support for TPM 2.0. Don’t worry if you don’t know what TPM is – most of us didn’t know it, before Microsoft made it a Windows requirement.
TPM, or the Trusted Platform Module, is a computer-level security measure designed to protect your computer from hackers. Computers built over the last five years should have TPM, but older machines do not. Although you are free to install Windows 11 on unsupported hardware, it is not recommended. As I mentioned in my article about failing to install Windows 11 on my previous PC, the safest way to buy a new PC is to update to the latest Microsoft operating system.
TPM 2.0 requirement
But even if you have a new PC, you may still fail to meet the TPM 2.0 requirement. While some systems have TPM enabled by default, others do not. That was the case with the 3080 Ti building I just bought. I used the Microsoft Health Check system and met all the requirements except for TPM 2.0. Since this was a new PC, I knew it had TPM – I had to figure out how to turn it on.
Microsoft explains what steps you must take to enable it on single PCs, but the information is scattered over a few pages. Thus, we have included this simple guide to help you enable TPM on your PC.
How to enter the BIOS
You will need to enter your system BIOS to enable TPM. This may sound scary, but it is a straightforward process.
Another way to enter the BIOS is to press Start and go to Settings> Update and Security> Restore> Restart Now.
After your PC restarts, you should be greeted through the options menu. Select Troubleshooting> Advanced Options> UEFI Firmware Settings> Restart.
Alternatively, holding down the Shift key while restarting your computer should display the BIOS menu. Some systems allow you to enter the BIOS by pressing Delete or F1 during reboot – you will usually see a text that tells you which key to tap to enter the BIOS during the process of restarting your PC.
Enables TPM in BIOS
Once you have accessed your BIOS screen, you may need to search and search for the TPM-enabled option.
If you can’t find any setting to enable it, don’t despair: some modern PCs have other TPM options. For example, my PC has an Asus motherboard with PTT, which is a type based on different firmware, so to enable I had to navigate to Advanced> Get PCH-FW Configuration, where there was an option to enable PTT.
So if you can’t find TPM changes in your BIOS, check your motherboard manual (or Google your motherboard model) to see if there is an alternative to
When you’re done, save and exit.
Launch the Health Check app again and you should now say that your PC meets Windows 11 requirements.
Note that Windows Update (available in Settings) may mean that your PC does not meet all the Windows 11 upgrade requirements, even though Microsoft’s PC Health Check application (specifically designed to ensure that your PC meets the requirements) system (Windows 11) states that you have been deleted in order to upgrade. I don’t know why this difference is possible, but it won’t stop you from progressing.
You can check if you have successfully enabled TPM by going to Settings> Update and Security> Windows Security> Device Security.
Under Security Processor, select Security Processor details. A list of specifications will indicate whether TPM is on or off. In my case, it was.
After all, it is safe to install Windows 11 on your PC. Now you are free to enjoy all that Windows 11 has to offer.
While enabling can add additional steps to update Windows 11, it does not require much technical knowledge.
.ISO. Please keep that in mind while Windows 11 will work on PCs that do not meet its basic system requirements, will do so in an “unsupported” state and thus may not receive critical updates and security patches.
