2 login screens at startup - no password required

1) Prior to the last win 10 update, when I turned on my PC I briefly got login background wallpaper without (!) a usier icon (UI), user name (UN), or "welcome" message (WM)- the pc then went directly to the desktop - no login required.
2) After the update I lost the login background wallpaper & acquired the UI, UN, and WM - the PC did not require a login.
3) After internet reading & various edits, I got the background wallpaper back, and lost my specific user icon. But, the generic UI, UN, and WM still appeared. I did (do) not have to enter a password... the desktop appears after a pause.
4) I wanted to get rid of the UI (user icon), UN, and WM altogether (turn on PC, blank login screen with background wallpaper, and then Desktop). I did the following:
a) Run: Local Security Policy
b) Added "Additional Rules" to "Software Restriction Policies"
c) New Path Rule
d) Pasted in "C:\Windows\SystemApps\Microsoft.LockApp_cw5n1h2txyewy" (please don't laugh!)
5) Now I get two (2 !) login screens:
1st no background, generic icon, my first name only, and "welcome" message
Then (!) 2nd - backround wallpaper, my full nme, and "welcome message"
6) I'm clearly moving backwards, although I still don't have to type in a password.

Any help in (at least) getting rid of one of the login screens would be greatly appreciated!
