Process Explorer答案只能运行一次，但是即使重新启动计算机后，您可能仍希望应用此方法。为此，可以使用PowerShell：

它基于此Stack Overflow答案。基本上，您为它提供了要保护的进程列表和要防止的用户列表，并且适当地摆弄了进程的ACL。将其保存为.ps1文件（用户可以读取但不能写入的文件），然后将包含如下内容的批处理文件放入用户的Startup中：
powershell \path\to\script.ps1 ('snippingtool', 'mspaint') 'Guest' -executionpolicy bypass
保护snippingtool.exe并mspaint.exe从（在截图工具和画图）的游客被杀害。
请注意，这必须在这些进程启动之后运行。您可能必须在PowerShell脚本块sleep 10之后添加一个或一个左右Param。完成后，尝试使用任务管理器终止这些进程将导致以下情况：
另请注意，如果您使用的帐户是管理员，或者更确切地说具有，则它没有任何用处SeDebugPrivilege。
在它们的窗口上单击X或使用应用程序自己的关闭功能仍将使进程退出，因为所有进程均可自由决定停止运行。您可能需要隐藏通知区域，如另一个答案中所述。同样，由于这些重要的流程以来宾用户身份运行，因此该用户是流程对象的所有者，并且无论如何都可以调整ACL，或者可以使用PROCESS_VM_WRITE功能来涂抹流程的内存并使它们崩溃。可以通过为添加空白ACE OWNER RIGHTS并将其更改'PROCESS_TERMINATE, PROCESS_SUSPEND_RESUME, WRITE_DAC'为来解决这些问题'PROCESS_ALL_ACCESS'。
通过GPO拒绝对任务管理器的访问将阻止用户使用任务管理器（显然），这是最直接的解决方案，但是没有什么可以阻止他们运行自己的taskkill不遵守组策略的程序（或）。最好是，您要捍卫的进程与您要捍卫的进程的用户身份不同。
当然，如果您的客人愿意为解决这些各种“保护”而竭尽全力，那么您可能会遇到更多的社会问题，而不是技术问题。
