how to delete drivers

hello,
       i want to delete user key driver completely from the image. how
should i implement it.

i have done following things to remove,but no result.

1. Removed userkey name from the Dir file and compiled using build -c
2. removed registry entries in both platform.bib and platform.reg
3. at last i have done the make sysgen.

  but when i check armvi release folder i can still find userkey.dll, how
can i completely remove it

How about right clicking on the component and excluding it? Or something
similar?

Tried that but still i can find userkey.dll in release folder

Play around with Mini2440.bat.

Try setting "set BSP_NOBUTTON=1"

tried but still i can find dll in release folder
