How to remove Thunderbird as default e mail client

more options

My Thunderbird installation displays Thunderbird as my default e mail client. I can see that box checked in the settings. But it's greyed out so I can't change the setting. How do I uncheck that box and remove Thunderbird as my default e mail client?

Hi there , It seems that Mozilla is using really aggressive policy. Wasn't Microsoft ordered ages ago to avoid such behavior by the US department of whatever ? And wasn't the case brought by Netscape ? This is really disgusting. Sorry guys but the first advice "uninstall TB" was the only working solution.
