Can't Stop Edge from Opening at Startup

I imagine this is very old news, but I thought I'd put it together, maybe Microsoft or Community can help.

I’ve got Windows 10. After an update, Microsoft Edge is now apparently permanently running at startup. Since I primarily game using the machine, the Edge startup is an annoyance, repeated now hundreds of times. I must shut off the program each time to see my background. So, I embarked on a journey to disable Edge at startup. It’s been fruitless.

I can only assume marketing elements at Microsoft said: “Let’s make Edge activate on startup to sell it. The people are sheep, and they won’t be able to not use the program, if IT’S ALWAYS THERE.”

I’ve now spent hours looking for fixes and trying to resolve this. Here’s what I tried (nothing worked):

1.

Open Task manager > Startup Tab
Look for Microsoft Edge then Disable

(Edge wasn’t listed)

2.

Press Start then search Settings
Select Accounts. >Click Sign in Options.
Scroll all the way down and turn off "Use my sign-in info to automatically finish setting up my device after an update or restart,"

(Turned it off, didn’t stop it)

3.

Press WIN+R to open Run
Type in shell:startup then hit Enter.
Look for Edge inside the folder then delete it.

(Edge wasn’t listed, the folder was empty)

4.

Click on start menu (Left bottom of screen) Type cmd in keyboard Command prompt option will appear. Right-click on Command Prompt. Select Run as Administrator. Then type sfc /scannow (Space before slash) there and hit enter. Let the scan be 100% and completed. Then: Again click on start menu(Left bottom of screen) Type cmd in keyboard Command prompt option will appear. Right-click on Command Prompt. Select Run as Administrator. Then type DISM.exe /Online /Cleanup-image /Restorehealth (Space before all slash) Hit Enter Let the scan be 100% and completed. After that restart your pc. Then please try updating from this https://support.microsoft.com/en-in/help/3159635/windows-10-update-assistant link manually then again restart the pc. You will be updated.

(I may have been updated, but it didn’t help. I restarted the computer, tried all the above fixes, no help.)

(BTW, this fix was given to me by a Microsoft Help Chat agent. Funny I couldn’t find it online. Well, now you will be able to.)

(Microsoft or somebody, please tell me I’m wrong, and I don’t have to see this crappy marketing scheme play out again indefinitely.)
