How can i modify program icon heights on the taskb

You know, in windows 7, how you have the 1.5cm thick icons on the taskbar? how can i edit registry to achieve that in windows vista? i already have the width set proprely, not the height, if anybody knows anything about this, please help!

Screen shot the area you want to modify, I'll try and help.

here you go!

Google some superbars for vista

most of the results are just people asking for things like ports from win 7, no real findings, and the windows 7 theme for vista is so boring....

Unlock taskbarm drag it a bit up.. lol

that gives a ugly result: very small icons, big taskbar.... it was suggested to me that i open the msstyles file and try to modify it, but i don't know how to go about doing that, ill try notepad...

okay i've already failed at that method, ill try downloading vistastylebuilder (pirate, of course!) and see what happens
