WhyNotWin11 is the second open source tool that you may run. In the case of my Surface Go device, Win11SysCheck confirmed that the processor is the culprit by stating (Unsupported Intel CPU detected) this gives you a clear message. You get a DOS window in which all checks and the returned values of them are listed. Just ignore the error and continue with the execution.

The tool is new, and that is the reason for the error. Note that you may get a SmartScreen error when you run the tool on Windows - an installation is not required. You can download a precompiled copy of Win11SysCheck form the project site. It is more detailed than Microsoft's own tool, as it lists checks and the outcomes in the interface. Win11SysCheck is an open source tool that tells you if a PC is compatible with Windows 11, and gives you the reason if it is not. But you can use third-party tools like Win11SysCheck and WhyNotWin11 to determine if your computer will run Windows 11, and why it may not. Update: You can no longer Download the PC Health Check app, since Microsoft has pulled it from their servers to avoid flak from users while the company tests Windows 11's compatibility on older systems such as the 7th-gen Intel chipsets.

Microsoft has updated the tool in the meantime to highlight why a device is not compatible. You had to check each component that is tested manually.įor the CPU, you had to find out the make and model on the device, and then search for it on Microsoft's listing of compatible processors by AMD, Intel and ARM. Even recent computer systems may not be compatible with Windows 11 most of the laptops and PCs that Microsoft sells under its Surface line are not compatible. While that is okay if a device is compatible, not revealing why the device is not compatible is a problem. The first iteration of the tool returned Yes or No, basically.
