* A new look task bar. Centred similar to the macOS dock by default but lacking the ability to position on any other screen edge?
* A new start menu design
* Windows have rounded corners
* Some built in apps such as the Xbox app and Microsoft Store have been redesigned (Xbox Game Pass and xCloud built into the Xbox app)
* New touch keyboard (SwiftKey?) with improved speech recognition
* New haptics when a stylus is used
* Teams integrated into Windows
* Support for Android apps built into the OS (using Intel Bridge technology whatever that is?). Apparently this works via the Amazon App Store although I am not sure what this actually means in a practical sense?
* A new widgets fly out for weather, news, etc. (appears this will require you login with a Microsoft Account)
* Improved windows snapping with a dynamic (based on your screen(s) size and layout) UI built into the maximize button
* DirectX 12 improvements (unsure if limited to Windows 11 only?)
* Auto HDR for games
* Improved experience when switching between tablet and desktop modes
* Apparently there will be "Windows 11 ready" PCs for sale "today"?
* Microsoft say they have been working with AMD, Intel and Qualcomm to optimise the silicon for Windows 11
* 40% smaller Windows Updates
* TPM 2.0 and UEFI are hardware requirements. No legacy BIOS compatibility at all?
* A Microsoft account and internet connectivity is required for Windows 11 Home setup
* 64-bit processor required (no 32-bit build at all?)
* There is a universal mute button in the system tray so you can mute yourself system wide rather than in the app
Probably some other things I have missed
