Windows 11 Runs on 1-Core Pentium 4 Because Microsoft Forgot to Disable It

Windows 11 hardware requirements made a mockery of by an Intel Pentium 4 processor

As the screenshots below show, Microsoft considers the Intel Pentium 4 661 a supported 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.

Hence, the PC Health Check tool sees that the Pentium 4 661 has a 3.6 GHz boost clock, which satisfies one of Windows 11's requirements. Curiously, the tool states that the Pentium 4 661 has two or more cores, even though it lists it as having one.

@Carlos_SM1995 has even got Windows 11 (Build 22000.258) running on a Pentium 4 661. Supposedly, Windows Update still works too, highlighting the ridiculousness of Microsoft's overtures regarding Windows 11 compatibility.

    Again, software often sees hyperthreading as 2 "logical processors".

    It's a Microsoft product, it's surprising it doesn't list it as a Motorola 68000 with 512 cores and 16 bytes of RAM.

    If you look in Windows 10/11 task manager, it makes the distinction between "Cores" and "Logical Processors", so at least someone at Microsoft knows the difference.

    The screenshot [notebookcheck.net] from the article shows exactly what the tool is reporting. "The processor has two or more cores.", followed by "Processor Cores: 1" and a green check mark. The only response I have to that is...."Huh?"
