The steps to fix Windows on your laptop will depend on the specific issue you are facing. However, here are some general steps that you can follow:
Back up your important data: Before you begin any troubleshooting, it is important to back up your important data to an external drive or cloud storage to prevent data loss.
Check for updates: Make sure that your Windows operating system is up to date by checking for updates. Go to Settings > Update & Security > Windows Update and click "Check for updates." If any updates are available, download and install them.
Run a virus scan: Run a virus scan to check for any malware or viruses that could be causing issues. Use your preferred antivirus software or use Windows Security, which is built into Windows 10. Go to Start > Settings > Update & Security > Windows Security and click "Virus & threat protection." Click "Scan options" and select the type of scan you want to run.
Use System Restore: If you recently installed new software or made changes to your system settings that caused issues, you can use System Restore to revert your system to an earlier point in time when it was working correctly. Go to Start > Settings > Update & Security > Recovery and click "Open System Restore." Follow the on-screen instructions to select a restore point and complete the process.
Perform a repair installation: If none of the above steps work, you may need to perform a repair installation of Windows. This will reinstall Windows while preserving your personal files, settings, and installed programs. You can use the Windows installation media to perform this process. Boot from the installation media and select the "Install now" option. Follow the on-screen instructions and select the "Upgrade" option when prompted.
If you are not comfortable performing any of these steps, it may be best to contact a professional or seek assistance from your device manufacturer.
