I've got it and tried it. It works great, although its system requirements are a little absured. None of my computers except the one I am using to type this from right now works with Windows 11. I am not in Windows 11 right now, I am in Windows 8.1. I am gonna try and see if WinToUSB will install the Windows 11 build to an external SSD (via USB SATA) and boot it on my HP 15-f233wm (the laptop Windows 11 told me was incompatible).
For quick reference, here are the system requirements for installing on UEFI:
4GB of memory
Secure Boot support
Trusted Platform Module support
52GB or larger disk drive
Also, code from Windows 8 is still present. If you go here,
https://www.askvg.com/collection-of-windows-10-hidden-secret-registry-tweaks/ you can find tweaks. Not all of these work, but a few such as the Wi-Fi flyout and the Classic Volume flyout still work. If one opens Explorer and pastes this in: explorer.exe shell:::{05d7b0f4-2121-4eff-bf6b-ed3f69b894d9} you can access Notification Area Icons control panel applet. Also, the old personalization control panel from Windows 8 is still present as well. Enter these commands in Explorer to access the various pages of it.
