Answer 1

Hi,

First, check whether the KB5126256 update is installed on the second computer.

To check, go to Settings > Update & Security > Windows Update > View update history.

If it is installed, please follow the procedure below:

Open the Command Prompt (as administrator) and run the following commands, one at a time:

sc.exe config DiagTrack start= auto

sc.exe start DiagTrack

reg.exe add "HKLM\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides" /v 4011992206 /t REG_DWORD /d 2 /f

After running the commands above, restart your computer, open the Command Prompt (as administrator) again, and run the following command:

cmd /c ClipESUConsumer.exe -evaluateEligibility

Check to see if the ESU enrollment window appears.

Answer 2

The second laptop must independently meet every consumer ESU prerequisite before Enroll now appears; update it to Windows 10 22H2, install all current Windows updates including the latest ESU Licensing Preparation Package, restart, and then return to Windows Update.

Compare the two laptops

On the laptop that only says it is eligible:

Press Windows key + R, enter winver, and select OK.
Confirm it reports Version 22H2. Consumer ESU supports Windows 10 22H2 Home, Professional, Pro Education, and Workstations editions.^1^
Open Settings > Update & Security > Windows Update.
Select Check for updates, install everything offered, and restart. Repeat until no further updates are offered.
Open View update history and look for Extended Security Updates (ESU) Licensing Preparation Package for Windows 10 (KB5126256). This package updates the licensing and enrollment components; it prepares the device but does not enroll it by itself.^2^
Return to Settings > Update & Security > Windows Update. The expected result is an Enroll now link. Select it and complete enrollment.

The preparation package requires Windows 10 22H2 with a security update released on or after October 14, 2025, and must be installed after that security update. Windows Update should install it automatically once that prerequisite is present.^2^

Check account and management eligibility

If the link remains absent, compare these items with the working laptop:

Sign in using a non-child Microsoft account that is an administrator. A local account can be used initially, but enrollment will prompt for an eligible Microsoft account.
The laptop must not be in kiosk mode.
Consumer enrollment is not offered to devices joined to Active Directory or Microsoft Entra ID, or enrolled in mobile-device management. A device that is merely Microsoft Entra registered remains eligible.
If the working laptop was enrolled with the same Microsoft account, choose Enroll now > Add device on the second one. One consumer ESU license can cover up to 10 eligible devices.^1^

Enrollment options and timing can also vary by region, so identical laptop models do not guarantee identical enrollment screens.^1^

If “Enroll now” appears but fails

Microsoft resolved an ESU enrollment-wizard failure with KB5071959. That update applied to consumer Windows 10 22H2 devices not yet enrolled in ESU. Current cumulative updates should include earlier fixes, so first install all updates now offered rather than seeking an old standalone update.^3^

After updating and restarting:

Open Settings > Update & Security > Windows Update.
Select Enroll now.
Complete enrollment or select Add device when using the Microsoft account that enrolled the first laptop.
Return to Windows Update. Successful enrollment is shown there, and the laptop can then receive ESU security updates.

The “enrolled for important quality and security fixes” message on the first laptop indicates its enrollment is already complete; enrollment is per device, even when the hardware is identical.
