In my experiences, it's Windows Update in the background causing the lag. Doing it's shitfuckery things, planting it's shitfuckery seeds, waiting for restart season to trigger the bloom...
It is funny though, "Updates! You need to restart!"
"Oh, okay!"
Restart > GRUB auto boots to Linux.
I know it's a future me problem, but I'm in Windows for work like once a month these days. That's fine.
I've seen this meme many times, but for the first time I'm seeing Dr Ian Malcolm's dumb jock brother. I hope this is temporary and not something that can't be unseen...
