JSI Tip 8813. How does the 'Show updates' check box in the 'Add or Remove Programs' applet of the Windows XP SP2 Control Panel work?

Windows XP SP2 has a new feature whereby software vendors can list program updates along with the installed program in the Add or Remove Programs applet of Control Panel.

If you check the Show updates box near the top of the Add or Remove Programs dialog, after the program is listed, any installed updates are indented in the listing.

NOTE: The Show updates check box is un-checked by default.
