Users who got slapped with the “This PC can’t run Windows 11” message by Windows compatibility tool should try their luck again with Microsoft’s revised checker.
Dave Weston, Microsoft’s director of OS security, took to Twitter to announce the new version of the tool.
We just made updates to the Windows 11 PC Health Check App. It now provides more detailed info on requirements not met. This should help in cases where folks assumed CPU compat issues were TPM related https://t.co/hTWMe16DWO pic.twitter.com/eZLTZMOdjT

The new tool now pinpoints where the system failed the check.
The TPM, or trusted platform module, is a security chip that helps to establish a hardware root of trust. Windows 11 will require devices to have TPM 2.0 in order to be compatible.
But as per our previous coverage, many systems without a physical TPM can use the firmware-based TPM that runs in the main processor.
In a security document, Microsoft explained that TPM 2.0, the version mandated by Windows 11, supports newer cryptographic algorithms than its predecessor and offers a more consistent experience across different implementations.
Measured Boot, BitLocker, device encryption, UEFI Secure Boot and many other Windows services all either require or support TPM.
