Change Your Default "View Source" Application With A Registry Hack

Viewing web-page source files in Notepad is hardly a user-friendly experience. You can hack the registry to change which app opens source files, but using TweakUI is a better choice.

Load TweakUI (http://tinyurl.com/553fw6), browse to Internet Explorer > View Source. Click Change Program... and browse for whatever app you prefer. This only changes the setting for Internet Explorer; to change the View Source app for Firefox, type about:config in the address bar, scroll to view_source.editor.path, and change the setting by pasting in the full path to the application you want to use. (The Firefox tip works with XP and Vista, but you’ll have to tweak the registry if you want to do the same for IE under Vista.)
