Can't get rid of Windows 10 password
 

I recently had an OS meltdown and had to reinstall Windows 10 . The image I downloaded from Dell is apparently newer than the install I replaced: I tried to get rid of my login password using netplwiz, which I had done successfully in my previous installation. However, in the new OS netplwiz displays the same options as the previous version, but unchecking "Users must enter a uername..." has no effect. I still get prompted for a password when I boot or wake up the computer.

Does anybody know how to get rid of the login password?
