这就是我的工作。

LoadUserProfile

由于您还根据CreateProcessAsUser的文档指定了StartupInfo中的lpDesktop参数：

...您必须更改默认交互式窗口站和默认桌面的自主访问控制列表（DACL）。窗口站和桌面的DACL必须授予用户或hToken参数表示的登录会话的访问权限。

我的猜测是这是导致拒绝访问错误的原因。

但是，根据CreateProcessAsUser的文档，传递的令牌必须是主令牌。但是，您使用DuplicateToken创建令牌，该令牌仅创建模拟令牌。

因此，您需要使用DuplicateTokenEx创建主令牌，并将TokenPrimary（= 1）作为第5个参数，并在CreateProcessAsUser调用中使用此令牌（如果这是即使在桌面和WindowStation上设置权限后也能正常工作。
