Taskbar resize registry

[Nepsyde]

I am wanting to reset the taskbar size via registry. I am not looking for how to lock/unlock the taskbar (I know that already), most searches on this returns how to lock/unlock. I am needing the entry (how to do it from registry) that will sets the taskbar at 1TB high, 2TB high, 3TB high etc.

cheers

(friend messed up my registry by adding weird tweaks and i can't seem to resize it to normal size)
