When you try to open a file and you haven't set a handler for a file extension, a window pops up in XP saying:
"Windows cannot open this file:"
To open this file, Windows needs to know what program created it. Windows can go online to look it up automatically, or you can manually select from a list of programs on your computer.
What do you want to do?
- Use the Web service to find the appropriate program
- Select the program from a list
This is really irritating because no one would ever want to use 'the Web Service' anyway. BTW Microsoft, look up Web Service at wikipedia.
To skip that step, make a file with the following contents, and open it and the registry setting will be automatically imported into your system.
