在Windows 7中调试shell扩展

我试图用Visual C ++ 2008在Windows 7中调试shell扩展（IContextMenu）。我在注册表中设置了DesktopProcess = 1，并将主机应用程序设置为explorer.exe。但是当我启动调试器，它启动explorer.exe，然后从进程中分离。不调用shell扩展的DllMain。

I'm trying to debug shell extension (IContextMenu) in Windows 7 with Visual C++ 2008. I have set DesktopProcess=1 in the registry and set host app to explorer.exe. But when I start the debugger, it launches explorer.exe and then detaches from the process. DllMain of the shell extension isn't called.

在调试器中启动与在Windows XP + Visual C ++ 2008中没有任何问题的完全相同的设置的相同代码。

The same code with exactly the same settings launched in debugger without any problems in Windows XP + Visual C++ 2008.

任何想法如何在Win7中调试shell扩展？
