In terms of privacy, I believe Windows collects a ton of data even if all telemetry is disabled; granted this is an older article, so it might have changed since*.

Your best option is probably running Windows inside a qube in Qubes OS and ensuring that the qube doesn’t have direct access to internet. But, at that point, why not consider switching to Linux instead? Because, you’d have to run at least another qube (with either Linux or *BSD on it) to grab the files off the internet from in the first place.

EDIT: lol, I just noticed it said “window” in the post and not “Windows”. I thought the mentions of “blackout curtains” and “storm shutters” was OP either making a joke or some reference I didn’t get. LMFAO, I didn’t even notice the “Thank me in advance”. Guess I should probably go to sleep after this. Good shit-post OP!
