Run the Windows Update troubleshooter

The Windows Update troubleshooter checks the services and files that Windows Update needs and repairs common problems on its own. On Windows 11 it runs in the Get Help app.

You need
An internet connection. An administrator account for some repairs.

Before you start

  • Write down the error code Windows Update shows, if any (for example 0x80070002). It helps if the troubleshooter does not fix the problem.
  • Restart the PC once and try the update again: a pending restart blocks many updates.

  4. Read the result

    Wait until Get Help finishes. If it found and fixed a problem, it says so and asks whether this solved the problem. Answer the question so it can offer the next step.
