You can uninstall it with winget uninstall cortana, never gave me any issues, works like a charm. Removing edge will break some stuff though, you need some edge render thingie for certain programs like Weather.
What about winget? I ripped out a whole bunch of stuff (like cortana) from W10 when winget became available. Best thing MS has done for windows in years
I really like consent-o-matic on firefox. You can set your cookie level to (dis)allow, and it goes through them automatically when you land on a site.
There is "i dont care about cookies", but I do care, I dont want your cookies and I dont want to go through your dark patterns!
