I'm going to have to leave the proper content review for someone else as I don't have access to a Windows machine to properly test this/troubleshoot etc.

Just a few things below that caught my eye.

Also, and this is just a idea I'm not 100% convinced with, what do you think about converting any note boxes to GitHub markdown alerts? Temporarily, while this is hosted on GitHub. The note box divs won't render differently here, so they'll just be normal paragraphs and headings.
Caveat with GitHub alerts is that

1. We'd remove headings as they're not quite the same as our note boxes
2. Would need to convert back and add headings once we can host the guides on the TOP site again

Thanks Zach, great job with the lesson updates, it looks great!

I wasn't able to fully test it myself by following the guide yet, but should be doing it soon. Will share more comments if needed then.

One quick comment I had is about line 122, specifically the You are encouraged to do your research on saving the machine state, should you so choose.
I've seen snapshots causing a few issues in earlier versions, so I wonder if perhaps omitting that specific bit about snapshots might avoid some future issues? Linking a couple of instances as examples 1, 2

I suspect that at one point the Safely Shutdown part was added due to that, at least my impression from the way it was originally written.

The new step-by-step is very clear, I bet it'll reduce the amount of issues we have to help with, thank you.

Yeah that's a good idea, I can omit the snapshot information. And I am leaving the safely shutting down section at least.

Thank you!!

A heads up that alerts do work, they just need > as well. Though tbh on second thought, might just be better off without since once we get these hosted on the TOP site, we'd need to convert them back anyway.

Some small grammar suggestions.

Not used yet to reviewing and sending suggestions directly via Github's interface, so hopefully this was sent correctly.
