If you have a corrupt profile in Windows 10 there are two easy ways to remove it and rebuild it:
1: REMOVE CORRUPT WINDOWS PROFILE USING GUI:
- CONTROL PANEL > SYSTEM AND SECURITY > SYSTEM > ADVANCED SYSTEM SETTINGS (from the menu on the LEFT)
. - Click SETTINGS button in the USER PROFILES section
. - Click on the user that has issues and click the DELETE button (note that you can not delete the profile you are using)
2: REMOVE CORRUPT WINDOWS PROFILE MANUALLY:
- Open File Explorer (This PC) and go to C:\USERS\
. - Right click on the profile you want to remove and select DELETE
. 
Open RegEdit
.- Expand HKLM > SOFTWARE > MICROSOSFT > WINDOWS NT > CURRENTVERSION > PROFILELIST
. - Click on each entry until you see the PROFILE IMAGE PATH that matches the one you want to delete
. - Right click on that entry and select DELETE
Reboot and sign in with the username you just removed and a nice new profile should be created.

THIS did not show a deleted user whose name pops up at BOOT

I am not sure what you are referring to. It SOUNDS like you are referring to a BIOS password which would be completely unrelated to Windows or this article.
Alternately you could be referring to an old user profile that still exists in Windows even though you have deleted the files from C:\USERS. If that is that case, the solution is to remove them:
1: click the START button and type USERS
2: click on ADD EDIT OR REMOVE OTHER USERS
3: click on the dead user and select REMOVE
I hope that helps

If you are comfortable messing with the Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI
Navigate to that Key and delete its content, OR rename that key to LogonUI.bak
That removed user will not show up in the last logged in list anymore;
