Windows updates come directly from Microsoft. They are never offered by Alienware Update. Microsoft rolls out updates in stages, and the best option it to wait until it becomes available to you as an update in Windows Update. There are currently a few known bugs and one can cause a system crash during installation. How to get it 
As you know, Windows 11 22H2 is available. I created a USB installation drive and updated another Windows 11 computer I have. Can I do the same with my Aurora R12? Note that my Aurora R12 is around 2 months old, and it came with Windows 11. My question: Is this something I should do, or should I wait for it be made available via "Alienware Update" or via "Microsoft Windows Update"?
