Hello ChuckM47,my name is Luiz Cruz independent consultant and I'm here to help you;
I understand that Edge opens during Windows startup;
Initially I recommend that you try the solutions below;
Open Edge and go to Settings;
Click System and Performance;
Disable the "quick start" and "Efficiency mode" options;
Disable Edge on startup;
Access the Task Manager;
Click Startup and disable Edge from startup;
Restart the PC and check if Edge still starts with Windows;
Hope this helps, see you soon!
