likely sourced from our operating systems account details.
the real question is, why are our operating systems giving software access to that sensitive information?
i would have expected the "PC name" to be available information, mine is called "DESKTOP-ksjdhbfak" or something like that, not my real first name, i certainly would not have expected the windows account sign-in username to be visible to anything except Microsoft..it just goes to show, i learn something new every year.
Here is a tip Never post your error report of any game in any chats because this report also shows all your cp info. Sample on Eternum player John some thing posted his errors report. Now everyone has his info. And any blackmailer could use this against you. I will not go into detail how a hacker/blackmailer can do this. Just be careful every thing you do in the cyber world is being seen by someone and they could try to use it against you for profit or just to hurt you.
