Windows Latest was released on October 19th (US time) in “Windows 11 shows Intel’s decade-old Pentium 4 CPU as supported”, “Intel” released in 2006 even though it does not meet the system requirements of Windows 11. “Pentium 4 661” reported that it has cleared the processor requirements of “PC health check app”.
It seems that some users have installed Windows 11 on a PC running the Intel Pentium 4 661, bypassing the requirements of TMP 2.0 and Secure Boot. This user reportedly was able to apply updates like Build 22000.282.
The system requirements required to use Windows 11 are as follows.
| Hardware requirements | |
|---|---|
| CPU | 64-bit compatible CPU (1GHz or higher, 2 cores or higher) |
| Mem | 4GB |
| Storage | 64GB or more |
| Firmware | UEFI (Secure Boot Support) |
| TPM | RPM 2.0 |
| GPU | DirectX 12 or higher (WDDM 2.0 driver) |
| Display | 9 inches or more (8-bit color, resolution 720p) |
The Intel Pentium 4 661 is a processor shipped in 2006 and does not meet system requirements. In this regard, Windows Latest points out that it may have been because Microsoft forgot to add code that recognizes these processors as unsupported, and said it wasn’t supported.
Even if the “PC Health Check App” check shows that it meets the requirements, such old devices may be shown as supported even though they are not supported. Even if you can install it, please note that Windows Update may not be applicable in the future. Windows 11 should be used on hardware and environments that meet the system requirements presented by Microsoft.
