If you are searching where are the command prompt properties saved for the respective title, the answer is look in registry under 'HKEY_CURRENT_USER\Console'.
So I've deleted all custom setups, because I hate when I setup something for command prompt and then when script will change the title or there is different title (btw. you can change it in script with command 'title'), the prompt is not setup how I would like. I've decided to edit the default setting rather (values of key 'HKEY_CURRENT_USER\Console').
