We were forced to set up a Microsoft account to get Windows installed. We also got stuck with Edge basically telling us it was going to automatically import data from other browsers with a window we couldn't dismiss even with Alt+F4. We know it's intentional that the opt-out doesn't work, but it's still infuriating.
So far we haven't gotten an activation nag, but we have had some major issues with network performance. Windows claims it's getting a 150 Mbit/s connection, but the networking hardware says the speed is less than a tenth of that. It's not connecting to the 5 GHz network and it's not clear it's even trying to. So while this is just about enough speed to watch an HD video, it's nowhere near sufficient for game downloads. Again, it's just stunning seeing the OS blatantly lying about things that can be easily verified elsewhere. Microsoft feels they can outright lie about the performance and behavior of Windows because they're a corporation with a near-monopoly and we're just some creatures who are paying attention to what's really happening.
Once the initial setup stuff is complete, and assuming it is actually stable, we'll probably stop messing with it until it (perhaps inevitably) breaks again. Though the longer we sit here looking at downloads running at a tenth of the speed Windows claims it's getting, the more tempting it is to grab our Garuda Linux install media and fix the problem for good.
