Although I stick to the predetermined browser option when installed it doesn't work when a link (http) is opened. What's the matter? Further more, Tor doesn't appear among the installed programs list of the Windows control panel! What am I doing wrong?
The Tor browser does not need installation. All you need to do is unpack the torbrowser-install package. It does not appear among the installed program list of the control panel because it is not installed. It is only unpacked. There is HTTPS Everywhere plug-in activated in Tor browser to provide encrypted version of web pages to users for their protection when an encrypted version of a site is available.
You're not doing anything wrong. The Tor browser isn't an installed program. It's just an executable in a folder that you've extracted somewhere. As such, it can't be specified as the default application for HTTP/HTTPS.
In Tor ticket 12763, I see this comment by mcs:
Replying to lunar:

I agree that applications may be able to take advantage of the fact that the Tor Browser is the default browser. I don't think making TB the system default is something the Tor Project is likely to recommend or do automatically, but some people may want to do so.
I am closing this bug.
I haven't found anything specific about setting the Tor browser as default in Windows, but maybe I didn't search enough.
