In my testing  I was able to set and read the registers back successfully however the exception which should be generated as a result of setting those registers do not get triggered. So in theory you are able to set and read hardware breakpoint registers back with correct values. But there is some configuration internal to windows which probably does not happen until we land in user code for generating those exceptions.
