got to say the one thing I appreciate the most about all of what you are doing is the dedication to digging to the exact fact i need to see to verify what you're saying is true. windows makes that very hard.
Great video as always, what i think would be really interesting is a video about networking internals of windows because i never found a lot of information about that. Ive read Windows internals 7th edition part 1 and am currently reading part 2 but there isnt anything about networking.
I will say this: my tool supports dark mode and for that I had to use some hooks and subclassing, but I didn't touch the scroll bars that are built into windows (like the list view), because they are very difficult to customize.
