winable.h在2005年7月已經從Windows SDK移除，因爲它的功能已經在winuser.h被複制。所以那時候決定花費更多的努力在更新winuser.h上，而這樣就相當於是在更新兩個文件的功能。（winable.h was moved from the Windows SDK in July 2005 because functionality was duplicated in winuser.h. It was determined at that time that efforts would be better spent on updating winuser.h to Windows Vista-level functionality rather than updating the functionality of both files.

若需要winable.h頭文件，可以到低版本的Visual Studio或者VC6.0 中找到並複製到新版的Visual Studio的相應文件夾中即可以繼續使用。
