1. Elevated privileges are required, so maybe we should handle them somehow nicely, with regard to that the tests can be run several times, and we don't want to click 'yes' each time, and maybe we don't wont to open separate admin console (anyway, it's unsafe).

2. Write an article about time travel debugging, common commands, howto's
