As you can see from te response, it is an odd query and, if actioned, would result in a loss of your OS.
However. IF you know what you are doing (I have done this from time to time, but only for testing purposes!) download and run the Microsoft program "Autoruns" This gives many options. One of these is to look at all your dlls and either disable or delete them.. It is on your own head if you delete the wrong ones!!
