LWE10198 : Howto get the personal favorite program back in charge (Windows XP vs. Vista)?
File extensions have been altered to another application after installation
Installation routines often make their application to default program for associated file extensions
Probably everybody knows this:
you douple click a shareware picture viewer or mpeg-player and afterwards this application always starts upon doubleclick, not the personal favorite-application...
This is caused by alteration of the extension definition in Windows registry (HKey_Classes_Root). There are basically two ways to get your standard back (without messing in the registry):
- define the default application for a certain extension (works fine, if only one or few exensions are involved)
- use repair or installation routines of favorite application.
however, this has been made a lot better in Vista. Under Control Panel, you find "Default Programs" (or the appropriate translation, in german it`s "Standardprogramme"). This let's you define every application per extension (as known from former Windows versions via Windows Explorer, Extras, Folderoptions -> Filetypes) or define an application according to it`s settings (like for example every extension used by internet browsers).
