If we will add shell extension or not is a future issue that will be addressed by our Product Manager but I just wanted to add that you will get the context menus if you run Explorer.exe inside the bubble. By default this will not work but with the trick provided here it is possible:

Hi,

Tortoise will not be possible at the moment, as it requires integration in explorer (for the icon overlays) as well as context menu's (already discussed before)

Especially the biggest pro for usage of tortoise, the icon overlays, will not be possible. You don't start the captured tortoise, but explorer. And explorer is a nasty one, as it is initially loaded as shell (your desktop). Every next instance is a derived one of that version. You could start the virtualised one but in the long run this will introduce more problems as positive points.

ThinApp is just not (yet) intended to publish shell extensions in a form some of us would like to have it. I personally don't think there are to many people in a company use tortoise however that do tend to have admin rights and want to fiddle with the system settings anyway. We have most problems providing managed desktops using virtualised apps to developers and systemmanagement.

Good luck evaluating...

Kind regards,
Michael Baars
