在vb.net中以不同的用户身份运行新进程
我目前正在使用本地出品的方法在Vista中以不同的用户身份运行进程，但我无法逃避这种黑客行为并不理想的感觉（除了这样一个事实，即它会摧毁UAC，导致我崩溃有安全异常的应用程序，并迫使我完全禁用UAC）。 我的过程由两个项目组成（所以两个EXE文件） - 一个“界面”和一个“启动存根” - 以下是过程：
我有两个步骤的原因是我希望用户能够右键单击操作系统对（.EXE，.SQL，.MSC等）的默认操作并启动它的任何文件，并且仅限于ProcessStartInfo支持启用“UseShellExecute”，但该开关阻止我使用新的凭据，所以我一次只能做一个。
这会导致一些问题 - 首先，用户必须已经存在于计算机上，这意味着他们必须先在本地登录。 如果该用户没有本地配置文件，则所请求的应用程序有时会启动，但我得到注册表和配置文件例外，因为应用程序希望存在尚未存在的东西（例如注册表中的HKCU配置单元，而用户没有因为他们从未登录过）。
我知道我应该可以将我的应用程序的权限“提升”给他们请求的用户，启动我的新进程，然后撤消提升，但我无法找到一个好的代码示例，并且我不确定它会允许作为完全不同的用户运行。 这一切都有意义吗？ 我只是不禁觉得有更好的方法来做到这一点。
更新：我刚刚尝试了一些我在网上找到的模拟代码，但无济于事。 当与ProcessStartInfo结合使用时，尽管我已经使用提供的凭证激活了模拟，但似乎仍然使用我当前的登录名启动进程，而不是我提供的登录名。
有可能你必须使用Win32 API创建你自己的“shell”函数。
使用CreateProcessWithLogonW API，您可以在不同凭据下创建新进程，并可以选择加载用户配置文件信息。
在下面的代码片段中，如果替换
有关更多细节，请参阅CreateProcessWithLogonW API的文档。 通过这条路线，您可以完全控制并全面负责启动应用程序。
再次，这仅仅是一个例子，你可能需要稍微玩一下才能让它做你想做的事。

您可以尝试从您的应用运行runas。 这里有一些例子和选项。
试试这个模块：

使用Runprogram（）以user / pw y的方式启动程序。 程序只意味着.exe，参数写入“命令行”
