You have a laptop.
You want to install Windows 11 on the laptop.
However you got an unexpected error saying that you should visit https://aka.ms/WindowsSysReq for detail.
You visited the page but you are unsure what actually happened.
- The first common reason is that you do not have TPM 2.0 hardware.
Open Settings > Update & Security > Windows Security > Device Security
– If you do not see a Security processor section on this screen your PC may have a TPM that is disabled.
– If you do see a Security processor section on this screen then click Security processor details, and verify that your TPM Specification sub-version is 2.0.
If it is less than 2.0, your device does not meet the Windows 11 requirements.
Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard.
Trusted Platform Module provides
– A hardware random number generator,
– Facilities for the secure generation of cryptographic keys for limited uses.
Usually you can enable or disable TPM in the BIOS of your laptop.
If you have TPM 1.2, you can often update it to 2.0 by following the guide of your laptop providers. For example if you have a Dell laptop then you can check the guide here.
If you get “The TPM is Owned.” issue when updating TPM 1.2 to 2.0 then you can check a guide here. (Press F12 after your laptop is reboot.)
- The second common reason is that your laptop processor has not been supported by Windows 11.
Open Settings > System > (scroll down if needed) > About.
Search for processor name, e.g. i7-10610U.
You should find your processor name here if it is supported. For example the Xeon E3-1505M processor has not been supported.
- You can also download PC Health Check app to verify these 2 issues or identify other potential issues.
