Just had the new update and when it finished it asked for a pin number to get back into my PC, I did not want to have a pin number but it was giving me no other option, So i entered the one it was showing me and it said the pin number was not right!.
How can it not be right they bloody sent it to me, then it locked me out of my PC!, So asked it to send me a new pin number, which it sent to my yahoo account.
Only thing is i could not get into my PC, i had to boot up an old PC to get it, why the hell would i want a pin number in the first place as i am happy with my password, it's like they are forcing you to have it, your given no chose with the update.
I never wanted a Microsoft account that seem full of add tracking, location tracking, web site tracking and more, in the end i had to crack my own PC to get back into it !.
Also i never set you a Microsoft account in the first place, but some how they got my email address, my home phone number as i had an option to reset my pin by phone,Microsoft spyware!
