To restore Windows Update and enroll in Extended Security Updates (ESU) for Windows 10, use these steps in order:
- Run the Windows Update troubleshooter (Windows 10)
- Select Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters.
- Under Get up and running, select Windows Update > Run the troubleshooter.
- Let it complete, then restart the PC.
- Go back to Settings > Update & Security > Windows Update > Check for updates and try again.
- Repair system files used by Windows Update
- In the taskbar search box, type command prompt.
- Right‑click Command Prompt and select Run as administrator.
- Run:
Wait for “The operation completed successfully.”DISM.exe /Online /Cleanup-image /Restorehealth - Then run:
Wait until it reaches 100%, then close Command Prompt.sfc /scannow - Try Windows Update again and then the ESU sign‑in.
- Make sure the correct Microsoft account is used for ESU
Several ESU enrollment issues were fixed by changing how the Microsoft account is signed in:
- Open Settings > Accounts > Your info and confirm which account is shown.
- If a local account or the wrong Microsoft account is shown, switch to the correct Microsoft account:
- In Your info, choose Sign in with a Microsoft account instead (or use Manage my Microsoft account first if that option is not visible yet), then sign in with the account intended for ESU.
- After signing in with the correct Microsoft account, return to Settings > Update & Security > Windows Update and try the ESU/Account sign‑in again.
- If ESU region/account issues appear
Some users could not enroll in ESU until they:
- Signed in with a Microsoft account instead of an old local account.
- Turned on location services and restarted the PC, then tried ESU enrollment again from Windows Update.
- If updates still fail
If Windows Update continues to fail with errors, follow the broader guidance in Troubleshoot problems updating Windows, including:
- Running the Windows Update troubleshooter again.
- Checking for specific error codes in the Windows Update history and applying the matching fix from the error‑code table.
Once Windows Update is working and the device is enrolled in ESU, security updates for Windows 10 can be received. If the device meets the minimum system requirements, upgrading to Windows 11 from Settings > Update & Security > Windows Update > Check for updates will then be possible.
