Suddenly there's a strangers name on my windows login screen

Thank you for the reply, I opted to reset windows 10 but used the option to save my personal files. It reinstalled windows 10 but the name was right there on the first sign in page. So right now that's where I was at until I tried to reply to your comment. I had forgotten my new Microsoft account password so I rest it. While doing this it came to a page where it shows what name you want to display and there was her name "Anna Charles" so I changed that to one of my names I use and then I continued on to reset my password. I haven't shut the computer down yet because I was in the middle of responding to your comment. Hopefully as I reboot my computer after this, it will now show my name. I hope anyway.

Thanks again,

Hello, 

unfortunatly it seems as though you are having a large issue right here. I must ask a few questions first though and it might help me uncover why this has happened and how you can sort it out!

Please answer with as much detail as possible if you cannot answer leave blank.

thanks in advance :)

1) Do you have a shared (family) microsoft account or is it a privatly owned account?

2) Have you ever given someone access to your account?

3) Have you downloaded malware or malicious software onto your computer by accident, or do you think you have any strange software that has appeared recently? 

If the person still has access to your account. I would highly recommend changing your password for your microsoft and bank details.

If you are facing anymore problems please feel free to contact me :D
