Simple and effective configuration. Well done!
Follow frogboy's advice about backups and a bit of common sense will guide you well.
Thanks for sharing!
Very fine tune configuration, that should supplement based on your current computer knowledge; optional case if you are inserting USB then better to have a tool like McShield to prevent it alongside of turn off the autorun completely by USB Protection Tool Free 1.0 .
Small update. I found a lifetime license I had for Malwareybtes so I activated the real-time protection. I have two external drives, one is a backup in case the other one fails. Redundancy is great.
