I am trying to enroll my personal Windows 10 PC in the Extended Security Updates (ESU) program. My system is Windows 10 version 22H2, OS Build 19045.6466. KB5126256 is installed, Windows Update reports no required updates pending, and I am signed in with a Microsoft administrator account. The “Enroll now” window opens briefly and then closes without an error message. I have restarted the PC and confirmed that no work or school account is connected. Please help me troubleshoot the ESU enrollment wizard.

    Hi! Check ESU Services and Status: Open the Command Prompt and view the ESU status in the Windows Registry.

    1. Type "Command Prompt" in the Search bar > Right-click the app > Select "Run as administrator."
    2. Type the following commands: WARNING: Type the entire command on the first line > Press ENTER > Wait for the command to complete > Run the next command in the list.
    reg.exe query "HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\ConsumerESU"

    Expected result: ESUEligibility REG_DWORD 0x2 ESUEligibilityResult REG_DWORD 0x1

    • ESUEligibility must be 0x2
    • ESUEligibilityResult must be 0x1
    • If different numbers are returned, send me the results and perform the next steps.
    1. Still in the Command Prompt, enter the commands below to enable the User Experiences and Telemetry (DiagTrack) service if it is disabled. This service is required for ESU to function.
    sc.exe config DiagTrack start= auto
sc.exe start DiagTrack
    1. Run the command below for Windows to re-evaluate whether the machine is eligible.
    cmd /c ClipESUConsumer.exe -evaluateEligibility
    1. Restart your computer > Run the first command and see if the results change.

    Because build 19045.6466 already includes Microsoft’s fix for ESU enrollment-wizard failures, repair the Windows component store and system files before running Enroll now again.^1^

    1. Repair Windows components

    1. Search for Command Prompt.
    2. Right-click it and select Run as administrator.
    3. Run these commands in this order:
    DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
    1. Do not close the window until SFC reaches 100%.
    2. Restart Windows after both commands finish.
    3. Open Settings > Update & Security > Windows Update > Enroll now.

    DISM repairs the Windows image used by SFC, and SFC replaces missing or corrupted protected system files.^2^

    If DISM or SFC reports that repairs could not be completed, retain the exact result for the repair-install step below.

    2. Check the remaining eligibility details

    The conditions already confirmed—Windows 10 22H2, current updates, KB5126256, an administrator Microsoft account, and no connected work or school account—do not need to be repeated.

    Check only the requirements not identified in the question:

    • Go to Settings > System > About and check Edition. Consumer ESU supports Windows 10 Home, Professional, Pro Education, and Workstations.
    • Confirm the Microsoft account is not configured as a child account.
    • Confirm the PC is not in kiosk mode or managed through MDM. A merely Microsoft Entra-registered device can still qualify.

    KB5126256 prepares the licensing and enrollment components but does not enroll the PC by itself. Enrollment must still be completed through Windows Update > Enroll now.^3^^4^

    Do not apply unofficial registry changes or attempt to launch an undocumented ESU executable. Microsoft documents the Windows Update wizard as the consumer enrollment route.

    3. If the wizard still closes: perform an in-place repair install

    A matching ESU case where the window opened and then closed unexpectedly recommended an in-place upgrade after DISM and SFC.^5^

    Back up important files first, then:

    1. Create Windows 10 installation media using Microsoft’s Media Creation Tool.
    2. While signed into the existing Windows installation, connect or mount the media.
    3. Open the media in File Explorer and run setup.exe.
    4. Select Change what to keep.
    5. Select Keep personal files and apps.
    6. Select Install and allow the PC to restart as required.
    7. Run Windows Update afterward, restart, and retry Enroll now.

    Choosing Keep personal files and apps preserves personal data, installed applications, and settings while reinstalling Windows components.^6^

    Avoid booting from the media and choosing a clean installation; that removes files, applications, and settings.

    If enrollment still closes after the in-place repair, this is no longer the enrollment defect that build 19045.6466 was intended to correct. Contact Microsoft Support and provide:

    • Windows edition and build 19045.6466
    • Installed status of KB5071959 and KB5126256
    • DISM and SFC completion messages
    • Confirmation that the wizard still closes after the repair installation
