If your Windows 11, version 24H2 update is stopping at 35% and the Windows Update troubleshooter is not running, you may want to consider the following steps:
- Check for Compatibility Issues: Ensure that your device is not affected by any known compatibility issues with the 24H2 update. Microsoft has applied compatibility holds for devices with certain drivers, such as the sprotect.sys driver, which may cause devices to become unresponsive during the update process.
- Use the Windows Update Troubleshooter: If the troubleshooter is not running, try accessing it through the Settings app. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters and select Windows Update. If it still does not run, you may need to restart your device and try again.
- Manual Update: If the automatic update fails, consider downloading the Windows 11 Installation Assistant or the media creation tool from Microsoft's website to manually install the update. However, be cautious as it is recommended not to attempt manual updates if your device is affected by compatibility issues.
- Backup and Clean Install: If all else fails, backing up your data and performing a clean installation of Windows 11 using a recovery image might be necessary. This can resolve persistent update issues but will require reinstalling your applications afterward.
- Contact Support: If you continue to experience issues, consider reaching out to Microsoft Support for further assistance.
Following these steps should help you address the update issue you're facing with Windows 11, version 24H2.
