Locked out of computer after win10 update

I am locked out of my computer because I purchased the computer online i never needed a user name or password so I never changed any of the precious owner's admin settings. On Saturday the computer automatically upgraded to windows 10 and is now
asking me for a password, which I don't have and I do not have access to any of the previous owners information! I purchased the computer for quickbooks pos for my business. So now I cant log into my computer or access my pos to run my business! Please help!

Hello Javiea, and welcome to Ten Forums. *Smile

What happens when you try to sign in to your administrator account?

 

i cant remember the admin password

 

If you sign in with a Microsoft account, then you could do OPTION THREE on any computer to reset your password online at Microsoft. The new password will sync to your PC if it has an Internet connection. Sometimes it may take around 24 hours to sync though.

I don't think that's the problem.
I can get into the laptop using the same password as I did before.
What happened was it went from admin to guest and from domain to workgroup
I didn't think that changing the PC name would lock me out like that
every time i try to do anything to make changes or even try updating norton i get a message

user account control
do you want to let this app make changes to your pc
to continue type an administrator password and click ok

but only the no button is lit and nowhere to type a password
i couldn't even do a print screen to show you

 

As a test, see if you may be able to do a system restore at boot using a restore point dated before you changed the computer name to see if it may be able to quickly undo and fix this for you.

System Restore Windows 10

 

the admin password i use to use when i was the administrator didn't work so i couldn't get in
the current account is still guest

 

In that case, you might see if you may be able to do OPTION FOUR in the tutorial below to enable the built-in Administrator account, sign in to the account, create a password for it, then change the computer name back.

it says "you currently don't have permission to access this folder when i try to open the config folder.
I really appreciate this!!

 

Just to verify, are you doing OPTION FOUR in a command prompt at boot and not from inside Windows or Safe Mode?

 

no, it is from inside windows
i don't have a usb or recovery drive (can't create one without admin permission)

 

That would be why then. It can only be done in a command prompt opened at boot after booting from installation or recovery media.

You could create a USB on another computer (ex: friends?) if you like to boot from on your computer.

 

can i do from my computer?
