Account password problem after streaming Windows 10 upgrade

My friend upgraded her HP Probook 4525s from Windows 7 to Windows 10 via the streamed upgrade she was offered. She can't remember exactly what she did, but we have now a Windows 10 login screen for which the account is called "Recovery" and for which we need a password which we don't know.  Her own account password doesn't work.  I've tried enabling the built-in administrator a/c as you could with Windows 8 using a Windows 8 CD, but this doesn't bring up the command line at the login screen as it would with Windows 8.  Has anyone anyone seen this behaviour before and have any idea how to fix?

Hi Mark,
well when I upgraded, I had to login using the Hotmail Account password (this was the email id I had supplied in one of steps at time of upgrade)

the login name on screen was same for me as earlier but earlier password was not working, luckily I remembered the password for hotmail account so I was able to login.

later I was able to change the login to old username and password (change to LOCAL login)

so ask your friend to try to login using the Hotmail or whatever email ID she used at time of upgrade.

my second observation is that your Hotmail account has a RECOVERY Email ID.... maybe the password of THAT recovery account might work.

hope this helps and best of luck to your friend on this :)

I resolved this by using an offline windows password removal tool.  In this, I set her account to be active and removed the password both on her account and this new "recovery" account.  On rebooting, I was able to log into her account. Everything was working perfectly with her Windows 10 installation so I removed the 'recovery' account.
