Windows 10: i have a different name on my log in screen

a Person named Leo D.... name shows up in my log in screen. I just bought this computer a few days ago. the time is off and everything. I have tried to contact Microsoft about this but the phone doesn't work and when I do the online thing they tell me they have detected unsafe activity on my account and I cant make changes. The email is not mine either its a hotmail and the back up is a yahoo. I had my previous computer for about 7 years and nothing like this occurred before

Black Screen after Log on


Computer boots to windows log on,have no password here.After a minute on log on it go to a black screen,stays there forever. I can get to Task Manager from black Screen,lost on what to do next. Just want my Windows 10 back, not sure what caused this problem. Any Suggestion on what my next step should be?*Sad

 

Win10 log-in shows different name at log-in that is not mine, nor recognized!

On my Win10 PC, I am the only user, so did not set-up a password to access it/log-in. Five days ago, it requested I enter a password!! Followed the procedure to do so, and it has worked since then.

This morning, the log-in screen showed a DIFFERENT NAME instead of mine for the account holder!! I have no clue who, what, where, how this happened. My daughter checked Facebook and LinkedIn, one showed the person in Australia, the other in South Africa!

I immediately disconnected PC from network, and used the previously set-up password, and it allowed me in. This access and posting is from a separate, older PC (still running Win XP!! (which I miss!!))

I checked the Account Info, and it listed:

DIFFERENT NAME (an 'actual' name, that showed up on Facebook & LinkedIn)

my xxx.gmail account name below it

Administrator

My concerns:

• HOW did this happen?
• is the machine compromised? (security scans are current and supposedly clean)
• what is recommended resolution?
• what precautions should be taken?

Thanks!!

 

Black Screen after Log on

So this is not a BSOD ? Have a Windows 10 disc or USB Flash Drive made ? How are you getting to task manager Ctrl.+Alt+Del ? Any cursor on screen ?
