For Windows 11, try this in order:
- Run the Windows Update troubleshooter.
- Select Start > Settings > System > Troubleshoot > Other troubleshooters.
- Find Windows Update and select Run.
- Follow the on-screen steps.
- Check the internet connection and try the update again.
- Select Start > Settings > Network & Internet > Wi‑Fi.
- Confirm the PC is connected.
- Then go to Start > Settings > Windows Update > Check for updates.
- Restart the PC, then check again.
- A restart can clear apps or services that are blocking the update process.
- If updates still will not download or install, repair Windows system files.
- Warning: these steps require administrator permissions and command-line use.
- Open Command Prompt as administrator.
- Run:
DISM.exe /Online /Cleanup-image /Restorehealth - Wait for the success message.
- Then run:
sfc /scannow - Wait until the scan reaches 100%, close Command Prompt, and try Windows Update again.
- If the issue continues, reset the Windows Update components.
- Warning: these steps require administrator permissions and command-line use.
- Open Command Prompt as administrator.
- Run these commands one at a time:
net stop bits net stop wuauserv ren %systemroot%\softwaredistribution softwaredistribution.bak ren %systemroot%\system32\catroot2 catroot2.bak net start bits net start wuauserv - Restart the PC after the commands finish.
- If third-party antivirus or security software is installed, temporarily uninstall it, update Windows, then reinstall it.
- Make sure the reinstall method and any product keys are available before removing it.
Since disk space is already available, the most relevant next steps are the Windows Update troubleshooter, restart, system file repair, and Windows Update component reset.
