PC health check says I'm eligible for windows 11 but update doesn't

Microsoft rolls out Windows 11 upgrades in phases, even to eligible hardware. Your PC might be in a later "wave." There could also be a minor driver or firmware conflict that the Health Check didn't catch, but Windows Update's more comprehensive scan did. This is the reason why you got this mistake of "PC health check says i'm eligible for Windows 11 but Windows update doesn't."

Your Best Action Plan: Registry Modification to Enable the Offer

This tells Windows Update your device is ready for Windows 11 and often triggers the upgrade offer.

Important: Create a system restore point before proceeding.

Press Win + R, type regedit, and press Enter.

Navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade

If the OSUpgrade key doesn't exist, right-click on WindowsUpdate → New → Key and name it OSUpgrade.

Right-click in the right pane → New → DWORD (32-bit) Value.

Name it AllowOSUpgrade and set its Value data to 1.

Right-click → New → DWORD (32-bit) Value again.

Name it ReservationsAllowed and set its Value data to 1.

Close Registry Editor and restart your PC.
