The product description here says "Windows 10 Pro (TE01-1254, 2020 Model)" and that's what I wanted; I am a retiree experienced with Windows 10 and don't want to spend my time learning and getting used to something else. BUT, after the pains of installing the the machine, connecting peripherals, connecting it to my network, copying my personal files over, a System->About tells me I'M RUNNING WINDOWS 11 PRO, confirmed by Winver, so I'm stuck.Giving an extra star because it seems like a nice machine.
