Confused, thank you!
I was in China used free vpn to get contact with skype support and accepted remote controll, but the stuff wrote dev.microsoft.com afterwards. I do not know if there were any corelation - later, hacker came into my computer via microsoft acount, i could not call for those service I payed, later, I could not call to skype contacts, later my skype was locked, I could not logg in.
I found also skype translator was in my contacts and Boot support also in my skype-none of them were verified by microsoft, I do not know how these happened.
and all my other contacts were added to my skype.
even today I see 2 windows show up when I call to China.
