I hate to rewrite but... My post resumes in 2 questions:
1) "What does it change in ipv6 when i disconnect so i can revert the changes it made?"
That is the first.
I dont even remember the several configs i made.
So, support can tell me WHAT DOES IT CHANGE, SO I CAN REVERT WHAT IT DID. ok?
Do you need me to explain further? Ok, I DONT KNOW WHAT CHANGES IT MADE AND IF THEY REMAINED.
Will untick a box restore the configs? Guess not.
2) "I also use SIMPLE DNSCRYPT on my windows, that put dns on 127.0.0.1:53 and 127.0.0.1:54
Shall i be worried about something when using the windows widget too?"
Maybe you think i must make a FULL INVESTIGATION on my computer to discover the changes the widget made...
