Remember that PC Health Check app Microsoft released to help users determine if their systems met all the requirements for Windows 11? The one that caused people to question why their PCs failed the compatibility test even on modern hardware? Microsoft ended up yanking it offline, and now an updated version is back, available to download from the Windows 11 landing page.
The app is fairly simple, in that it quickly audits PCs to see if they meet the minimum system requirements to run Windows 11. Those include a compatible processor with at least two cores and clocked at 1GHz or faster, 64GB or more of available storage, at least 4GB of RAM, and support for both Secure Boot and Trusted Module Platform (TPM) 2.0 technologies.
There are some underlying nuances to the requirements. As it pertains to the processor, having at least two cores and running at 1GHz or higher is not enough, it also has to be a model that is on Microsoft list of supported CPUs.
