Windows 10: Windows 10 login issues

I've just updated my wife's laptop to Windows 10 from Windows 7. She asked that I enable FastAccess, which I did, but immediately ran into troubles. It will now only allow access by facial recognition or by use of a password.
The problem is, there was no password entered at any time to allow access, and the facial recognition is somewhat buggy.
What I want to know is how to ensure I can get rid of the FastAccess software and still be able to login to the computer.
What I have done so far:
I have disabled passwords in account settings (the stupid thing keeps asking for a password)
I have disabled the FastAccess facial recognition (It keeps asking if we would like to use it when logging on)
I have played with the registry to disable the need for passwords (it says we don't need a password)
I have downloaded the Windows 10 programs to create a disk.
I have cursed, sworn and begun blubbering like a baby.
I don't want to get rid of FastAccess until I know we can log into the computer. Is there anything else you can suggest I try?
Thanks for your time.

:)

 

Windows 10 login problem

Hi. I installed windows 10 on my friends computer, and his computer has a problem with overheating, so when I wanted to type his account details, the computer shut down. Then when I reopened it, is displays "Other User" and under are two columns, where
it says to type the email and the password. I tried three different accounts and it says that the password is incorrect. Please, help!

 

Windows 10 upgrade makes my computer shut down randomly

I have the same issue. MY Windows 10 is a new OEM install. BECAUSE, last update fried my hardrive. So new SSD Drives, New OEM professional install and SINCE that install, nothing but random shutdowns. Professional diagnostic from a nationally known computer
center could not find anything. Thought it was a power cord issue. PLEASE UPDATE Windows 10. From the web searches I see Many Many people having this issue. SO, when it came time for my son to go off to college, we decided to buy him a MAC laptop.
