Trivial finds are often the most useful!
Since Windows 10, taskbar icons are no longer “links” and you can’t right-click them to get the “Run as administrator” option. This is *SO* frustrating if it is something that you rely on. You need to pin things to the Start menu, where you need to right-click, then select the More menu and then select “Run as administrator”.
No longer… right-click the taskbar icon and you’ll get the familiar “<application name>/Unpin from taskbar” options. Highlight the application line and right-click again and you get what you need.
