Plan to upgrade to Windows 11. What is the windows 11 25h2 cpu support?

Just heard Windows 10 is out of official support so I plan to upgrade my Windows 10 to Windows 11 24H2, as it is the latest one I can download from Microsoft.  I'm unsure about the Windows 11 25H2 C...

Microsoft has not yet released the official final CPU support list for Windows 11 version 25H2. However, based on the company’s established policies and historical data regarding Windows 11 25H2 CPU support, we can draw reasonable inferences about which processors will be compatible.

Check CPU Model

  • Press Win+R, type msinfo32, and view the specific CPU model under the Processor section.

Compatibility for Different CPUs

  • If your CPU is on the official support list: Updates will be automatically pushed via Windows Update after 25H2 release.

  • If your CPU is not on the official list: You can install 25H2 using the 24H2 method. The most reliable approach is to use a third-party USB installer, which bypasses system requirement checks.

  • Note: Unofficially supported devices may not receive all subsequent updates.

Conclusion

25H2 does not introduce new support for older CPUs. If your computer previously ran 23H2 or 24H2, it will almost certainly run 25H2 using the same method. The only real barrier is extremely old CPUs lacking the fundamental POPCNT instruction.
