windows 10 added a second user account sort of

Hi,
I set up a lot of pc's and I've had this problem before with windows 8.1. I set up a single user account with Microsoft account (email and password). Then I want the pc to never ask for password, so I run userpasswords2 and uncheck so password is never asked for and we go right to desktop on startup. I'm setting up 2 laptops right now and 1 works fine.

On the second laptop, windows 10 created a quasi-user in addition to the user account. quasi has same name, same email, and it doesn't exist in control panels/user. It has a shorter version of the user name when I sign in, i.e., name is Rancho and it auto displays ranch as the user name on log in screen, so I know Windows did this somehow.

When I turn on laptop or restart, instead of going straight to desktop, it shows log in screen. it says it cannot connect (connection is wi-fi, no other pc's have connect problem), it says there is a problem and I have to sign in. it has 2 accounts in lower left corner (both have the same account name and email). if I click on the top, it is the ms account, it supplies the email and logs in with just a password. If I click on the ranch account, it puts ranch in the user name, logs in with same password.

I'm guessing I have to add administrator account #2, delete the messed up account #1 and recreate it, then delete #2. trying to avoid that fun if possible. and it didn't work on windows 8.1 when this happened.

any ideas on how this silliness happens? Is there a fix?
thanks, tom

no solution but I have standard user and admin accts. both using the same PWL on both my Windows 10 OS on this PC on separate NTFS volumes and it did that also .

I use std user accts. on the web to keep some nasty's out things they don't need to be in like the MBR or syst 32 etc.
