Introduction

The file association Web service in Microsoft Windows XP Professional Service Pack 1 (SP1) extends the scope of information stored locally by the operating system about file name extensions, file types, and the applications or components to use when opening a particular file type.

Assuming that .BAK filetype is unregistered in your system, and when you double-click a BAK file, you'll be presented with the Web Service dialog as shown in the figure. When you choose the first option, Windows launches this website:

http://shell.windows.com/fileassoc/0409/xml/redir.asp?Ext=BAK

To skip this dialog.....

To prevent the dialog from being shown, and to proceed directly to the Choose Programs dialog, follow these steps:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer

Or the following location: (to apply changes to all user accounts)

HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer

If InternetOpenWith value does not already exist, you need to create one (REG_DWORD) and set its data value accordingly.

Another method

HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ System
