How do I stop Edge from automatically opening on start up? Windows 10 Pro 64 20H2

(No EDGE today) :) The reg hack worked (so far).

I have been using Linux (Ubuntu) for decades but Windows is my main machine on all 17 in my business. Because of Win 11 forcing the use of MS accounts I started the very long and complicated process of dual booting my MAIN machine. A Ryzen 5950x, 64gb of GSkill 3200Mhz ram, RX590 over to Ubuntu. Let's just say, it's not a very simple job because of the hundreds of programs I use. I use many virtual machines, I have a massive 400TB Raid 5 server with Enterprise networking etc. That machine runs GREAT off Linux. Raid and Linux and large data is awesome.

The problem is gaming. Running 3D graphics inside a VM is a problem and I refuse to run 2 video cards (1 with passthru) in my main machine.

If you just surf the internet, check emails, play internet games... then Linux is very easy to setup and use. It's almost install and go. BUT, if you have a very complicated setup like I have... migrating to Linux is quite complex. I have spent hundreds of hours researching things (terminal / command line) do fix issues in Ubuntu.

Ubuntu handles multi monitor quite poorly (I have a single 55" 4k monitor in the middle surrounded by 4 x 29" LG IPS monitors) and Ubuntu hates when you scale 1 monitor and not the others. They will fix it better in the future, I'm sure, but right now, it does cause issues. (Ubuntu 18.04 LTS and Ubuntu 20.x).

I can now spend most of my day in Linux. Shortcuts across the network kinda suck in Ubuntu to open documents. I like shortcuts all over my desktop and Ubuntu is a pain in the ... to get that working cleanly and quickly. Can't just drag icons from a browser onto your desktop. It won't work. Gotta do some messy things with .desktop files and... some things in Linux are great (stability, and it truly IS yours, update when you want, change only what you want changed). Other things, MS does way better. Installations, ease of use are better in Windows by leaps and bounds.

Of course, once Ubuntu cleans up installations (everyone using .deb files) and fixes certain annoying issues... then it should surpass windows. But, for the novice person... if they are doing more than surfing and checking emails... Linux is still too unpolished.

However, I can't stand forced cloud signins so I have begun the long complicated process of migrating my master machine (and then all 17'ish) of my rest of my companies computers over to Linux.

Also, WINE is getting better all the time. And games are now being designed for Linux especially thanks to Steam and Internet based games. So, more and more games will work in Linux every day.

If you cram it down my throat. I will avoid it at any cost. A shame too considering Edge finally started peaking my interest. There was some nice innovation and features that are new that I would have put into my own software if I had of developed it. :) Sadly, I refuse to use it due to the way it's endlessly pushed on me. Also, every computer I setup with all the thousands of customers... I hide the Edge icon from customers. Saves the future hastle of the browser version being tied to the OS. (cough cough IE). You could only get the newer IE when buying the newer windows. So, to save customers that headache, long ago we decided to preinstall Firefox and Chrome and hide all traces of IE/Edge on every system we sell and maintain. So, far... that's like 12,000+ computers (customers) that have no clue what Edge is.
