Windows 10: How to change order of users on Windows logon screen

I have three users (all with local accounts) on my PC and some time ago I disabled the auto-login using the process described here:
Solved Help with multiple users login screen!

This worked perfectly as the users appeared in alphabetical order as follows:
UserA (with the user picture in the centre of the screen)
UserB
UserC

Recently, the order has changed to (I don't know why!):
UserB (with the user picture in the centre of the screen)
UserA
UserC

I would like to change the order back to how it was originally, as UserA is the primary user of this computer. UserA currently has to click on 'UserA' and then 'Sign In' rather than just 'Sign In'

Note: UserB is the only account that is password protected.

Does anyone have any ideas how to do this?

Many thanks

:)

Change windows 10 system logon screen background?

For the past few hours I've been searching for how to change the background for the system logon screen in windows 10. By default, it's the "hero" background.

In windows 7, you could add a registry key in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background in order to change the background of the logon screen, but that does not work
in windows 10.

I have also found advice directing me to What's With Tech? however many users have commented that using this utility requires a reimage of their system because
it damages the EFI partition in some way.

I would like to be able to change the background of the system logon screen from the "hero" background to an image of my choice, ideally
without using an external utility, especially one which has the potential to damage the bootloader of my system.
