I heard that the IT department seems to use a program that periodically resets the default browser back to Edge.

Edge is very hard to use. I asked ChatGPT for AI assistance.

I have tried various methods such as modifying the registry, etc., but none of them worked.

The only effective method is to manually go to:

Windows > Applications > Default Applications > Vivaldi

and click on the default browser.

It is very troublesome, I have to click it 3-4 times a day.

Does anyone know how to write a BAT or CMD command to change the default browser back to Vivaldi?

This way I can schedule it to automatically change back every 10 seconds.
