Custom credential providers don't load when you first log on

This article provides a workaround for an issue where custom credential providers do not work when you first log on.

Applies to:   Windows 10 - all editions
Original KB number:   4073719

Symptom

Consider the following scenario:

• You have a Windows 10-based computer that is not joined to a domain.
• Custom credential providers are installed on the computer.
• You log on to the computer for the first time after it starts.

In this scenario, the custom credential providers are not called.

Cause

This is by design. A Windows 10 update improves the Use my sign in info to automatically finish setting up my device after an update sign-in option. This feature is used for first logon. Therefore, custom credential providers do not take effects.

Workaround

Warning

Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this issue, disable automatic system logon of the last user by setting the following registry key:

• Location: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
• Value name: DisableAutomaticRestartSignOn
• Value type: dword
• Value data: 1
