As someone that has been working around weapons for the better part of 20 years, I disagree with your statement of not being blamed.
It's unfortunate yes, but whoever had that weapon in their hands and pulled the trigger should hold some blame.
If anyone ever hands you a weapon, movie set or not, it should be checked.
I do understand that it doesn't quite work that way but that's how it should be. Anyone handling a real weapon, especially during the course of ones job, should be required to go through training.
I primarily run Linux but absolutely understand the need for things that only work with windows so I dual boot. That being said I use AtlasOS which cleans up W10 pretty good. I don't have any of the crappiness that is currently hitting users.

Also here's another site that has some information on AtlasOS as well as some other tools.

I know it says for gaming but I use solidworks as well as some other software and my idle resource usage has went way down and it runs so much better.
