With mullvad, proton or iVPN, just enable lockdown mode or what proton calls the "permanent" kill switch.
That should block all unprotected traffic with no issue
Edit, I used policy plus to delay my quality updates by 30 days and my feature updates by 365 days and a couple of days ago I paused my windows updates because I saw britec09 talking about how some of the more recent updates to windows 11 will cause bluescreens sometimes. So I'm not affected.
Stop calling people "consumers"!
We're customers, we're users, we're people that businesses have dealings with, we're people who use software and goods for our personal use. We're citizens of the countries we were born in.
Cars consume gasoline, fire consumes whatever it burns, people aren't consumers.
A consumer is a gaping maw that eats everything until there's nothing left, a customer or a home user is a person.
Don't use the de-humanizing terms corporations want us to use.
