It is because Microsoft has changed the minimum system requirements, therefore which makes it impossible for some computers to operate Windows 11.
Among the companies whose computers need to be ready for the debut of Windows 11, ASUS has shared additional guidance on what motherboards are prepared for the new operating system, and you can see the full list in the adjacent photo.
Worthwhile to learn is that these motherboards come with TPM 2.0, so they support Windows 11 by default, though ASUS warns this security feature may not be enabled for everybody.
“If your existing Windows 10 PC is running the most current form of Windows 10 and meets the above mentioned minimum hardware specifications, it may be upgraded to Windows 11. Apart from system requirements, please take notice of the TPM settings in your motherboard. TPM is an international standard for a secure cryptoprocessor that’s been around for a long time. However, it’s disabled by default on most motherboards, which prevents proper installing of Windows 11,” ASUS says.
How you can see if TPM 2.0 is available
If you’re not sure in case your computer supports TPM 2.0 and it is therefore prepared for the change to Windows 11, you can figure this out quite fast.
All you need to do is click on the Start menu and then type tpm.msc. This command should launch the Trusted Platform Module Management screen, and when TPM 2.0 can be obtained in your device, you need to see a label reading Specification Version: 2.0 in the lower right corner.
Additional instructions regarding how to enable the TPM on your motherboard are available at ASUS for every model.
