Running Windows 10, version 1607, build 14393.222

[Gizmo-542]

On start up the lock screen only shows the 3 standard icons in the lower right hand corner. It does not show user name or anything else that might get me past this. No keyboard function or mouse click gets me to the sign on screen. The only think I can do is select restart from the power icon. Then it starts up as it should. What can I do to get past the lock screen and on to the sign on screen?

from the login screen, press the power button but before selecting anything, hold down shift and press restart
this loads advanced start up
choose troubleshoot
choose advanced
choose start up repair - this will scan PC and maybe fix this - will ask for logon info

On another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB - its a handy boot disc if nothing else.

I have seen this happen a few times recently and I am not sure why.

if there is anything on the pc you cannot afford to lose, try: http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/

you probably have two choices, reset or fresh install. Both require you to reinstall all programs again but a reset is slightly less painfui

reset:
change boot order so USB is first, hdd second
boot from installer
on screen after languages, choose repair this pc, not install.
choose reset this PC
two choices, save files and settings (files = library folders like music, documents, etc., Settings = logins), or wipe it all
Note: I don't know what causes this problem, whether its a windows function not working or your user, so a reset keeping files/settings might be a waste of time... i just don't know why Windows does this.
Whichever choices, win 10 will restart and reinstall itself

Fresh install - if your previous install of win 10 was an upgrade from win 7, and your PC is fairly new, Win 10 may want you to wipe entire hdd C is on before it will install, so make sure to copy everything off drive before proceeding

change boot order so USB is first, hdd second
boot from installer
