Given the specs (and also the price), windows 10 (or event 11) is not OK. It comes with a genuine copy of Windows 10 and being capable of free upgrade to Windows 11. I gave up after few uses simply because Windows will occupy 100% CPU, 100% Mem and 100% Disk all the time for its surveillance services. Opening Chrome simply grill this little machine and triggered a blue screen. I re-installed Linux Mint XFCE4 and everything works perfectly. I streamed videos from Chrome for 5 hours and it is as stable as rock. NOTE: this machine is capable of 4k@60Hz but could only do 4k@30Hz since it comes with an HDMI port. 4k@60Hz only works with a DisplayPort for this CPU. This is not big deal for me as I mainly stream 1080p@60Hz
