c#-在Windows XP登录屏幕(.NET / Pinvoke)上运行进程(WITH GUI)

我需要编写一个小的服务来在登录屏幕上运行应用程序(带有gui,例如calc.exe).

我已经找到了这个问题(和答案)：
Running a process at the Windows 7 Welcome Screen

如果您不了解其工作原理,请阅读代码注释：

        // grab the winlogon process
        Process winLogon = null;
        foreach (Process p in Process.GetProcesses())
        {
            if (p.ProcessName.Contains("winlogon"))
            {
                winLogon = p;
                break;
            }
        }
        // grab the winlogon's token
        IntPtr userToken = IntPtr.Zero;
        if (!OpenProcessToken(winLogon.Handle, TOKEN_QUERY | TOKEN_IMPERSONATE | TOKEN_DUPLICATE, out userToken))
        {
            log("ERROR: OpenProcessToken returned false - " + Marshal.GetLastWin32Error());
        }

        // create a new token
        IntPtr newToken = IntPtr.Zero;
        SECURITY_ATTRIBUTES tokenAttributes = new SECURITY_ATTRIBUTES();
        tokenAttributes.nLength = Marshal.SizeOf(tokenAttributes);
        SECURITY_ATTRIBUTES threadAttributes = new SECURITY_ATTRIBUTES();
        threadAttributes.nLength = Marshal.SizeOf(threadAttributes);
        // duplicate the winlogon token to the new token
        if (!DuplicateTokenEx(userToken, 0x10000000, ref tokenAttributes, SECURITY_IMPERSONATION_LEVEL.SecurityImpersonation,
            TOKEN_TYPE.TokenImpersonation, out newToken))
        {
            log("ERROR: DuplicateTokenEx returned false - " + Marshal.GetLastWin32Error());
        }
        TOKEN_PRIVILEGES tokPrivs = new TOKEN_PRIVILEGES();
        tokPrivs.PrivilegeCount = 1;
        LUID seDebugNameValue = new LUID();
        if (!LookupPrivilegeValue(null, SE_DEBUG_NAME, out seDebugNameValue))
        {
            log("ERROR: LookupPrivilegeValue returned false - " + Marshal.GetLastWin32Error());
        }
        tokPrivs.Privileges = new LUID_AND_ATTRIBUTES[1];
        tokPrivs.Privileges[0].Luid = seDebugNameValue;
        tokPrivs.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
        // escalate the new token's privileges
        if (!AdjustTokenPrivileges(newToken, false, ref tokPrivs, 0, IntPtr.Zero, IntPtr.Zero))
        {
            log("ERROR: AdjustTokenPrivileges returned false - " + Marshal.GetLastWin32Error());
        }
        PROCESS_INFORMATION pi = new PROCESS_INFORMATION();
        STARTUPINFO si = new STARTUPINFO();
        si.cb = Marshal.SizeOf(si);
        si.lpDesktop = "Winsta0\\Winlogon";
        // start the process using the new token
        if (!CreateProcessAsUser(newToken, "calc.exe", null, ref tokenAttributes, ref threadAttributes,
            true, (uint)CreateProcessFlags.CREATE_NEW_CONSOLE | (uint)CreateProcessFlags.INHERIT_CALLER_PRIORITY, IntPtr.Zero,
            "C:\\Windows\\System32", ref si, out pi))
        {
            log("ERROR: CreateProcessAsUser returned false - " + Marshal.GetLastWin32Error());
        }

        Process _p = Process.GetProcessById(pi.dwProcessId);
        if (_p != null)
        {
            log("Process " + _p.Id + " Name " + _p.ProcessName);
        }
        else
        {
            log("Process not found");
        }

它适用于Windows7.在XP中,我在调用CreateProcessAsUser时收到错误1349 ERROR_BAD_TOKEN_TYPE(MSDN：令牌的类型不适合尝试使用.).

如何在Windows XP中实现这一点？它不一定是上面的代码,但应作为服务使用(具有系统帐户？).

谢谢你的支持

解决方法:

这绝对与特权问题有关(Windows Vista和7在安全性方面有显着变化).与其尝试获取winlogon.exe的令牌并模拟它,不如尝试通过WTSQueryUserToken获取用户令牌：

WTSQueryUserToken (WTSGetActiveConsoleSessionId(), out userToken);

用上面的语句替换用于获取令牌的OpenProcessToken行.

您的新代码应如下所示：

//        if (!OpenProcessToken(winLogon.Handle, TOKEN_QUERY | TOKEN_IMPERSONATE | //TOKEN_DUPLICATE, out userToken))
//        {
//            log("ERROR: OpenProcessToken returned false - " + //Marshal.GetLastWin32Error());
//        }

WTSQueryUserToken (WTSGetActiveConsoleSessionId(), out userToken);

做你的DLL导入是这样的：

[DllImport("Kernel32.dll", SetLastError = true)]
[return:MarshalAs(UnmanagedType.U4)]
public static extern int WTSGetActiveConsoleSessionId ( );

您只需要用此代码替换我注释掉的部分.
