Windows 10: signing into accounts in browser

I am having an issue when I go to sign on to some accounts.

Example my banking account. It will NOT let me type in my full user name. The user name is only twelve (12) characters. It only allows me to type in eleven (11) characters. How do I get the browser to accept longer user names?

Signing in into Administrator accounts causes automatic sign in into all other local accounts

As mentioned in the subject, whenever I login into my Administrator account, Windows automatically ends up signing me into other local accounts. This has become annoying now since every time I login into my Administrator account, the local accounts are signed
in passively and cause RAM consumption, to which the only solution I see is manually disconnecting from the local accounts through task manager.

Can anyone help me out in this issue?

Thanks

 

I see NO ONE has responded to this and I have done a lot of searching on my Windows 7 machine.

To me this is very very important and if ANYONE has a solution I would appreciate the help.
