I thought it would take a long time to check, and in an instant, the dialog 'I can run Windows 11 on this PC' was displayed. If you click 'Detailed information' ...
The Windows 11 page opened in a new tab of the browser, and a message stating that Windows 11 can be executed was displayed in the 'Compatibility check' item part that was clicked when downloading the check app.
By the way, if it doesn't work, 'Windows 11 cannot be run on this PC' is displayed.
Detailed information is also this street.
The scan content of the check app is used only for this app and will not be saved.

if Microsoft's Windows 11 upgrade checker is telling you that your PC isn't supported, check your BIOS. You'll need a TPM 2.0 chip and to have Secure Boot enabled in the BIOS pic.twitter.com/fL3s0nTCEJ

TPM is a security function required for 'BitLocker ', which is a storage encryption function of Windows, and is executed by a dedicated chip mounted on the motherboard or a CPU. Since BitLocker is rarely used outside of business, it is often disabled in the BIOS on home PCs and gaming PCs. It is also possible that the BIOS update has not been applied and the TPM is not 2.0. If the motherboard does not have a chip, it will be processed by the CPU, but AMD and Intel may not support TPM execution depending on the CPU generation.
If you don't know why you're diagnosed as not eligible for the free update for Windows 11, check to see if your TPM is enabled and your version is 2.0 or higher. To check the TPM, press the Windows key and type 'tpm.msc' to run tpm.msc as an administrator.
If TPM is enabled, you can check the TPM version like this. If TPM is not enabled, or if the CPU does not support TPM execution, the TPM status information will not be displayed.
