附录：根据文档，如果您不希望新进程与用户交互，则应该可以在不执行这些步骤的情况下使用 CreateProcessAsUser。我还没有对此进行测试，但假设它是真的，对于许多场景来说，这将是一个更简单的解决方案。
事实证明，微软已经在标题Starting an Interactive Client Process in C++ 下提供了用于操作窗口站和桌面访问权限的示例代码。从 Windows Vista 开始，在默认窗口站中启动子进程不再足以允许子进程与用户交互，但它确实允许子进程使用备用用户凭据运行。
我应该注意到微软的代码使用LogonUser 和CreateProcessAsUser 而不是CreateProcessWithLogonW。这确实意味着该服务将需要SE_INCREASE_QUOTA_NAME 权限，并且可能需要SE_ASSIGNPRIMARYTOKEN_NAME。最好用CreateProcessWithTokenW 替换它，它只需要SE_IMPERSONATE_NAME。我不建议在这种情况下使用CreateProcessWithLogonW，因为它不允许您在启动子进程之前访问登录 SID。
我写了一个最小的服务来演示使用微软的示例代码：

这必须与微软的示例代码相关联。然后您可以使用sc 命令安装该服务：
sc create demosvc-createprocesswithlogonw binPath= c:\path\demosvc.exe DisplayName= "Demo service for CreateProcessWithLogonW"
