推荐答案

您可以使用 Windows 终端服务 (WTS) API 做到这一点.这是你需要做的:
1. 使用本地系统作为您的系统服务帐户.其他帐户将无法使用.
2. 调用 WTSOpenServer，然后使用 WTSEnumerateSessions 检索会话列表
3. 您将获得 WTS_SESSION_INFO 结构的列表.那里的每个项目都代表会话.您只对 State 为 WTSActive 的会话感兴趣.
4. 在循环中为您在上一步中确定的每个会话调用 CreateProcessAsUser.从会话的 WTS_SESSION_INFO 结构中指定 sessionId.要运行的进程的名称将是您最喜欢的屏幕捕获实用程序.我没有使用任何这些，但在互联网上快速搜索发现了几个选项.

You can do that using Windows Terminal Service (WTS) API. This is what you need to do:
1. Use Local system as your system service account. Other accounts will not work.
2. Call WTSOpenServer, then using WTSEnumerateSessions retrieve list of sessions
3. You will get list of WTS_SESSION_INFO structures. Each item there represents sessions. You are only interested in sessions where State is WTSActive.
4. In a loop call CreateProcessAsUser for each session you identified in previous step. Specify sessionId from the WTS_SESSION_INFO structure you have for the session. The name of the process to run would be your favorite screen capture utility. I did not use any of those, but quick search on internet turns up few options.
