Have you have enough of the Windows 10 system tray widget slowing down your start up times, and just general irritation at its mere presence? I was, so I took the time to find out how to remove it.
This link, What is the “Get Windows 10” Tray Item and How Do You Remove It?, gives some details.
The simplest method is to use GWX Control Panel, available from the downloads page of its author, ultimateoutsider. See the user guide, Using GWX Control Panel to Permanently Remove the ‘Get Windows 10’ Icon.
