Uh oh, that sounds bad, my best wishes for your restart. If you are going that journey, please let us know to help you out in case of troubleshooting. Please have in mind to use a backup program e.g. like Macrium Reflect Free or Aomei Backupper Pro (can tell you about free license) using right after the first windows startup to have basic image. And please have in mind NOT to install any additional security software. Windows defender is really strong. I know that the windows firewall design has not been improved since XP, that's a pity. if you need additional security feel free to ask again, beyond windows pro there a lot under the hood.
