To add insult to injury it also automatically logged me in with my AD domain account after restarting Edge on version 86, even though we have a GPO to disable this behavior. Now the problem is back, a shortcut is once again created. Now everything works as expected! Then I ran an update of Edge from within Help->About and it updated to version 86. I eventually, grabbing for anything, went back and tested version 83. I also tried 'do_not_create_quick_launch_shortcut':true as this is what is supported for Chrome in Windows 10, the other value is for Windows 8 and below. This however makes no difference, it still creates a shortcut on the taskbar after starting Edge for the first time.

Setting this to true writes the value 'do_not_create_taskbar_shortcut':true into the master_preferences file. The MSI file now supports the parameter DONOTCREATETASKBARSHORTCUT.
