The two types of SELECT controls that are included in Windows Internet Explorer 7 are the Windowed SELECT control and the Windowless SELECT control. This article contains information about these controls.

The Windowed SELECT control was implemented as a wrapper of a native shell common control in Microsoft Internet Explorer 6 and in earlier versions of Internet Explorer.

The Windowless SELECT control was implemented as a fully intrinsic element in Internet Explorer 7.

The Windowless SELECT control was designed to replace the Windowed SELECT control in Internet Explorer 7. However, this design change has triggered some compatibility issues with Microsoft Office 2003 and with earlier versions of Office.

For Internet Explorer 7 to support the Windowed SELECT control in Office 2003 and earlier versions, the following registry subkey is added when you install Internet Explorer 7:

Windows7 64bit系統的註冊表分32 位註冊表項和64位註冊表項兩部分。

在64bit系統下，經過regedit中查看到指定路徑下的註冊表項均爲64位註冊表項，而32位註冊表項被重定位到：HKEY_LOCAL_MACHINE\Software\WOW6432Node。

應用程序操做註冊表的時候也分32bit方式和64bit方式。運行於64bit系統下的32bit應用程序默認操做32位註冊表項（即被重定向到WOW6432Node下的子項）；而64bit應用程序纔是操做的直觀子項。
