WhyNotWin11 is a free utility for PCs made by indie developer Robert C. Maehl, who also goes by rcmaehl. This tool is based on a script used to detect and scan your computer hardware to determine whether your machine is compatible with the latest Windows 11 operating system.

Windows 10 was long overdue for a follow-up, and Windows 11 finally came after 6 years. However, the new OS also came with certain hardware requirements that not all PCs were able to meet. With WhyNotWin11, users can get a better idea of the reason why that is.

How does WhyNotWin11 work?

When Windows 11 was announced, it was to the delight, as well as the dismay of a lot of users and fans across the world. It was great that we finally had a new iteration of the OS after years of waiting. However, while the new version will be available as a free update to Windows 10 users, it came with strict hardware requirements that Microsoft was a little too vague about explaining.

Enter, WhyNotWin11, a utility tool that you can run to shed some light as to why your PC hardware may or may not be compatible with Microsoft's latest and greatest. Coming in at under 3MB, this program can be run portably and on any machine that runs Windows 10 that you want. It will only take less than a minute to perform its scan on your computer. It will then provide a list of results right after.

There are 11 hardware requirements that you will need to meet for Windows 11, including your CPU, DirectX version, and the quite controversial TPM module, which is now known to be the main deciding factor of whether or not your PC can run the latest OS version. Microsoft's PC Health Check app can now do the same thing, so it's up to you which tool you prefer to use.

Everything made clear now

If you're excited about the possibility of using Windows 11, and want to know if your PC is compatible with it, you can use WhyNotWin11 to find out. It's portable, easy-to-use, and you'll get the results in less than a minute. Whether you opt to use this or the updated PC Health Check app, everything will be clear to you now.
