W2K下如何禁止用户的进程切换?
俺知道屏蔽CTRL+ALT+DEL不那么容易,但是否有简单的办法屏蔽ALT+TAB之类的切换.
俺想在俺的程序结束前不让用户切换到其他程序.
俺发现EA的游戏就是这样,应该可以实现.

8．禁止用户使用“任务管理器”
用户可以使用“任务管理器”对话框来启动和结束本地进程，查看和管理其他计算机上的进程，改变进程的优先级。通过修改注册表，可以禁止用户使用“任务管理器”。新建一个双字节(REG＿DWORD)值项HKEY＿CURRENT＿USER＼Software＼Microsoft＼ Windows＼CurrentVersion＼Policies＼System＼DisableTaskMgr，修改其值为1。
