so annoyed rn smth is choking my PC... loading screens take forever, textures pop in late, and a large online shooter stutters constantly, task Manager:

Disk 0 (C:) Active time 100%
Not responding
100% disk, and the response time numbers look scary. I suspect Windows Update, but I'm not suree how to prove it.
i already restarted the PC and closed everything i could find in teh system tray, disk usage dropped for a moment, then went straight back up as soon as the game loaded a new area. im about to throw this thing out the window lol
