如果您首次登录Windows 10时未加载您的自定义凭据提供程序，那么这篇文章将能够为您提供指导。凭据提供程序是用户身份验证的主要机制——它们目前是用户证明其身份的唯一方法，这是登录和其他系统身份验证场景所必需的。

Windows 凭据提供程序框架^{(Windows Credential Provider Framework)}使开发人员能够创建自定义凭据提供程序。当Winlogon想要收集凭据时，Logon UI会向每个凭据提供程序查询它希望枚举的凭据数量。毕竟，提供商已经枚举了他们的磁贴，登录 UI^{(Logon UI)}将它们显示给用户。然后，用户与磁贴交互以提供必要的凭据。登录 UI^{(Logon UI)}提交这些凭据以进行身份​​验证。

自定义^(Custom)凭据提供程序无法在 Windows 10 上加载

假设您有一台未加入域的基于Windows 10 的计算机，并且计算机上安装了自定义凭据提供程序。您在计算机启动后首次登录。在这种情况下，不会调用自定义凭据提供程序。

根据Microsoft的说法，这个问题是设计使然。Windows 10 更新改进了使用我的登录信息在更新登录后自动完成我的设备设置^{(Use my sign in info to automatically finish setting up my device after an update)}选项。此功能用于首次登录。因此，自定义凭据提供程序不会生效。

要解决此问题，您需要通过设置DisableAutomaticRestartSignOn注册表项来禁用最后一个用户的自动系统登录。

这是如何做到的。在继续进行注册表调整之前，请备份注册表^{(backup the registry)}或创建系统还原点，以防注册表操作失败。

启动注册表编辑器。

导航到以下注册表项：

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System

在右窗格中，双击DisableAutomaticRestartSignOn条目以编辑其属性。

然后将值数据^{(Value data)}设置为1。

单击确定^(OK)。

重新启动^(Restart)PC 以使更改生效。

And that’s it!

Custom credential providers fails to load on Windows 10

If your custom credential providers don’t load when yoυ first log on Windows 10, thеn this рost wіll be able to guide you. Credential providers are the primary mechanism for user aυthentication—they currently are the only method for users to prove their identity which is required for logon and оther system authentication scenarios.

The Windows Credential Provider Framework enables developers to create custom credential providers. When Winlogon wants to collect credentials, the Logon UI queries each credential provider for the number of credentials that it wishes to enumerate. After all, providers have enumerated their tiles, the Logon UI displays them to the user. The user then interacts with a tile to supply the necessary credentials. The Logon UI submits these credentials for authentication.

Custom credential providers fail to load on Windows 10

Let us say that you have a Windows 10-based computer that is not joined to a domain and 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.

According to Microsoft, this issue 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 the first logon. Therefore, custom credential providers do not take effect.

To work around this issue, you’ll need to disable the automatic system logon of the last user by setting the DisableAutomaticRestartSignOn Registry key.

Here’s how to do it. Before you proceed with the registry tweak, backup the registry or create a system restore point in case the registry operation goes south.

Launch Registry Editor.

Navigate to the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System

On the right pane, double-click the DisableAutomaticRestartSignOn entry to edit its properties.

Then set the Value data to 1.

Click OK.

Restart PC for the changes to take effect.

And that’s it!
