Can't login after upgrade to win10

[niels2]

Hi,
Today I decided to upgrade a test tablet/laptop (hp pavilion x2) to win10.
There are 4 user accounts on that tablet, all local accounts with no password (because it is just for testing).
When the upgrade to win10 was finished, I got a screen with a list of those 4 users and I can select them.
But when I select an user, I can not do anything with that user (no login button appaers).
I think it has something to do with the fact that all of the user accounts have no password...
Is this a known issue? Is there a workaround?
Kind regards,
Niels

Any one has solution to this? I have the same problem after an upgrade from Windows 8.1 to windows 10
i only have one user with a password, after a successful upgrade i used the laptop for a about 15 minutes before a new windows update forced a reboot. After the reboot i get to a log in screen but no where to type the password.
