用向導建立一個Win32程序“hello, world!”，然后用下面的內容替換整個CPP文件內容就可以了

//   : )  好東西噢

用CreateDesktop新建一個桌面，什么都沒有的桌面，然后在新桌面環境中運行了explorer所以就有了和windows一樣功能的桌面，這個時候你就有了兩個桌面了，下面要做的就是用SwitchDesktop切換不同的桌面了

在不同桌面中打開的程序在其他桌面的任務欄包括系統托盤上不可見，不過任務管理器中還是可見的這樣你就非常方便的做很多事了，很多...  而且還可以非?？斓霓D到正常狀態上可以讓會責罵你的人比如老板什么的無話可說，因為他們什么也看不到  : )

或者你也可以給你用戶定制一個個性化的桌面。改改上面的代碼可以得到你要的效果的。
