Microsoft's insistence on excluding most processors from running Windows 11 has caused plenty of outcry in the last few months.

Unfortunately, Microsoft excludes 7th generation Intel Core processors for the most part and any first-generation AMD Ryzen processor.

Intel released the Pentium 4 661 in early 2006, with a solitary core to its name.

Apparently, Microsoft forgot to add any Intel Family 15 (Netburst) SKUs in its unsupported processors list for Windows 11.
