Hello,
What version of Edge do You use?
From version 97 if i good remember there is "fast boot" so there is a edge process all the time.
After boot Windows there is a edge process and when i close all edge still there is...
Look i just close edge and edge process move from "Running" to background:
When i run edge background process vanish and move to running:
So edge process is always now in background... when i try kill process he run again.
Best Regards
