Windows 10: Switch mouse buttons -- also for lock screen

I switched mouse buttons to left-handed, I did this for all user accounts.
But when I go to lock screen, it often behaves at default settings.
How can I switch mouse buttons for the whole local machine, even lock screen?

:)

 

Mouse not working

The mouse on keypad working fine because it is showing on the screen but on the lock screen the mouses click won't work on the screen so I'm not able to sign in on the picture password and the shutdown button on screen below the 'switch sign in' is not working
so I can't shut my laptop down and I also can't switch the sign in because the mouse won't work.

 

Switch mouse buttons globally

I went into control panel and switched mouse buttons, I did this for all my user accounts.

But when I go to the lock screen, the mouse often reverts to default settings, and this is very confusing.

How can I switch mouse buttons for the whole local machine? There must be a registry hack for this.

And after I do this, will I have to undo the setting I made for the individual user accounts?

 

I do not have an answer for your question, but have you consider disabling the lock screen as a workaround?

 

1 how to do that? win 10 RS3
2 how will I choose between my various user accounts, if I have no lock screen?

 

If you by lock screen means the screen that shows time and date and you click on it to get to the login screen, then here are instructions how to disable it. I have done it on my computer.

Thanks. I guess I meant to say log in screen, not lock screen

 

My thought the Lock Screen goes back to the basics and custom settings have to be reloaded after it's unlocked.

 

Ok, sorry about that. It seems like others have the same problem but no solution:
