Registry Key To Autohide Taskbar

[waltereo]

Hi,

I try to enable the autohide by using the registry (I known we can do it by right clicking the bar and check autohide) .

On the computer I use, i just cannot the autohide by right clicking and checking autohise. So I cannot use a prog to monitor the change in the registry. That's why I need the exact key

Do someone known where is that key, and its value ?

Thanks a lot
