Been part of the dev build as soon as it was available and have had no major issues so far..
Its basically just a re-skinned Win 10 with some additional features added on.. I am pretty sure this was just going to be one of the standard Win 10 feature updates until a Marketing guy seen it and went ooo lets call it Windows 11.
But it runs fine, mainly use it for gaming and not had issues with any games either. I do have a brand new system tho so don't have to worry about old hardware.
