Howto remove Broadcom BT stack / driver?

[Flow]

I have a question:

How do I get rid of the Broadcom BT stack / driver on my BA WM2003SE ?
And do automatically get the MS BT Stack instead when the one from Broadcom is removed?

I've tried a Soft Reset (power button + reset) and then quickly resetting again when the programs from the Extrom are installed, but that doesn't help.

Thanks in advance. :)

It's very easy: there is no MS BT stack for 2003 (at least not in 2003SE on BlueAngel). You can get MS version only in wm2005.

Then why do I find it in the Registry?
