I'm a big fan of Windows 11, and I highly recommend it. With that said, the operating system has a huge problem -- it is incompatible with many older computers. This is by design, as Microsoft purposely blocks some older hardware. While there are ways to bypass the compatibility check, Microsoft can close them at any time, including possibly blocking future updates. It just isn't worth the hassle, folks. Ultimately, if the Windows 11 installer says your PC is incompatible, you should either stay on Windows 10 while it is supported or switch to Linux.
