>>Running Windows 10 64bit professional version 1803 I'm glad you mentioned that. Where in sam-hell do you find the info on OS version on this platform. There's no Control Panel!

START - SETTINGS - SYSTEM - ABOUT will show you. my desktop is Windows 10 Pro 1803 build 17134.48 installed 19/5/18 Laptop will show the same For the old style control panel you can get there by typing "control" in the windows search box bottom left
