Last month, Microsoft confirmed what was already suspected that Windows 11 Build 22621 is indeed an RTM candidate for the Windows 11 22H2 feature update due later this year. The system requirements for Windows 11 22H2 remain unchanged, according to Microsoft, though there’s a small chance that SSDs will become mandatory in the future as the Redmond-based giant pushes OEMs to use the faster storage option for Windows 11 systems.
While Microsoft hasn’t updated an official Windows 11 compatibility tool like the PC Health Check app, you can still use a trick that involves digging into the Windows registry to see if your system is ready to accept Windows 11 22H2 (Sun Valley). 2) or not.
This information is available under HKEY_LOCAL_MACHINE\Software, where the “TargetVesionUpgradeExperienceIndicators” subtree indicates whether your computer is 22H2 ready or if something is blocking its compatibility and ability to upgrade to Sun Valley 2 (SV2).
Subsection full address:
Inside this folder, the “UpEx” and “UpExU” values should be set to “Green” in case of a system ready for Windows 11 22H2. In this case, the value of “RedReason” must be “No”. On the other hand, for an incompatible system, these values should be “red”, not “green”, and RedReason should list the reasons that make it incompatible, such as not having TPM 2.0 or secure boot.
Here is an example of an incompatible system with an unsupported CPU and TPM posted by Twitter user Panu Saukko. The screenshot was taken on Windows 10 version 20H2, so the 21H1, 21H2, CO21H2, and NI22H2 update experience indicators are present.
More information on compatible or incompatible specifications is available in the “CompatMarkers/NI22H2” folder just above this one.
