Known Issue – Microsoft Edge Launching on Startup

Deleted I observed this behavior in default browsers like Internet Explorer and Legacy Microsoft Edge. The workaround was opening Settings->Accounts->Sign-in options and under Privacy , there is option called Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart and we could turn it off and then we observe this problem won't reproduce.

As I investigate, I observed that when user close down Internet Explorer or Microsoft Edge, it still running in background and has some session and even after shutdown, system assumes Internet Explorer was running and therefore when user turn on PC, they observe this behavior.

I recommend check this option and see if turn it off would solve the issue and if yes, it probably was the issue I observed in Legacy Microsoft Edge and Internet Explorer.
