My PC is Acer Predator G3-572. I have clean installed Windows 10 1903 using official ISO, but when Windows 10 OOBE experience starts, Acer's OOBE experience (like accepting Acer's terms, creating or logging into Acer ID) is missing, like when I had started it for the first time. OEM partition is still there and also the OEM folder in C. So can anyone help me in that regard? I tried Alt+F10 but this reset and Windows 10's Reset through settings are same. What I am trying to do is get back the Acer customised Windows 10.
