Using the PC Health Check app is fairly straightforward. Before deploying it for Windows 11 compatibility testing, download the software via this link (opens in new tab). Once you open the installer, it guides you through the installation process. After you are done installing the app, just follow the steps below. After completing the installation process, open Microsoft’s PC Health Check app.  Near the top of the app, you will see a section titled “Introducing Windows 11.” In this section, click the “Check Now” button.  Wait for a few moments while the app checks your computer’s compatibility with the new OS. After waiting, a window will appear showing whether or not your computer can run Windows 11.  Click the “Learn More” button to get additional information about the result and Windows 11. This button will open a browser tab leading to Microsoft’s Windows 11 page.  As of this writing (August 2021), Microsoft’s PC Health Check app is currently unavailable on Microsoft’s website. You can, however, find copies of its installer on other websites such as Softpedia. We recommend that you wait for the official app to be re-released by Microsoft but if you’re in a pinch, this should help.
