I have Win11 on a Notebook from Oct. and a Desktop from April, only issue I've had was the audio/sound device on the Notebook just flat disappeared. Nothing could find, not even Linux Mint or Hiren's Ultimate Boot CD. Got the OEM involved because of the warranty and they replaced the motherboard, no issue since. All the software I need on both machines is working fine, even the built-in games from Win7/8 and a Mahjong game from 2006. Even have old WordPerfect 12, Lotus SmartSuite 9.8 and Office 2000 working.
Both computers came with Win10 Pro with Upgrade to Win11, license included [in the sales ad]. I have other computers that can't properly run Win11, too old but still good with Win10.
