Program Change In Registry

The program with which a file opens can be changed by right-clicking
the file, selecting "Properties", clicking the "Change" button in the
next dialog & finally selecting the program with which one wants to
open the file from the list.

For e.g. HTML files, when double-clicked in Windows Explorer, opens in
IE (assuming that IE is the default browser) but they can be made to
open in some other web browser, say, FireFox (by double clicking the
HTML files) by right-clicking any HTML file, selecting "Properties",
clicking the "Change" button & then selecting FireFox from the list of
programs available in that machine.

Can someone please tell when this change in program is made, which key
(or value) changes in the Registry?

Thanks,

Ron

Look in HKEY_CLASSES_ROOT\

You'll see all of the extensions under there. Click on the exention you are
looking for like .html
