System check “PC Health Check” for Windows 11 is available again

    Microsoft has relaunched its "PC Health Check App." The application was supposed to determine whether Windows 11 is compatible with your computer, but it was taken offline in June after it informed users with fairly recent PCs that they couldn't run the system, but without providing any explanation. The software was previously exclusively available to Windows Insiders, but it is now open to everyone.

    When performing the first offline check, Microsoft said in a blog post that the app “wasn’t completely prepared to offer the degree of detail or accuracy you’d expect from us about why a Windows 10 PC doesn’t satisfy the requirements update.”

    Many of the problems were caused by the “Trusted Platform Module Version 2.0,” or simply TPM 2.0. The capability is required for Windows 11 security systems, although it is not available on all motherboards. To add to the confusion, some motherboards that support it do not yet have this option enabled in the BIOS. That is, if a machine with TPM 2.0 was switched off, the application would just notify the user that their processor was incompatible with Windows 11.

    To run Windows 11, the updated version of the application will display a message stating that “TPM 2.0 must be supported and enabled.” However, it is still unable to distinguish between motherboards that enable TPM 2.0 and those that just have the TPM 2.0 feature deactivated. It does, however, give users instructions on how to enable TPM 2.0.

    The software isn’t as precise as it should be, but it’s an improvement over the prior version. If your computer does not pass the first scan, it is important to double-check the application and the information in the TPM 2.0 activation instructions.

    Microsoft’s latest operating system, Windows 11, is currently accessible to some Windows Insider program participants and will be officially released on October 5th.
