To troubleshoot Windows 11, it is best to follow a systematic approach with several key steps:

• Run Windows Update to apply all available system and bug fix updates.
• Ensure the PC has sufficient storage space.
• Use the System File Checker tool to scan and repair corrupted system files.
• Verify network functionality by checking physical connections and using command-line tools like ping and ipconfig.
• Run built-in Windows troubleshooters tailored to specific problems, accessible via Settings > System > Troubleshoot > Other troubleshooters.
• Consider rolling back the system to a previous restore point if System Protection is enabled.
• As a last resort, fully reset or reinstall Windows 11, with data backup beforehand.

These steps can resolve most common issues in Windows 11, including network problems, unexpected restarts, or errors.

If Windows does not load, use Advanced Startup options by holding Shift while clicking Restart from the Start menu to access repair tools.

For update-specific problems, running the Windows Update troubleshooter or using command prompt commands to reset the update components can help.

This approach covers basic and advanced troubleshooting to keep Windows 11 running smoothly.
