Microsoft’s KB5049981 update for Windows 10 22H2 and 21H2 is the ultimate New Year’s resolution for your PC—out with the vulnerable drivers, in with the secure ones! While it tackles BYOVD attacks, it might also break SSH connections or have a Citrix-induced identity crisis. Happy updating!

However, if you’re using Citrix, you might want to grab some popcorn, because the update drama is real!
