boot - Is there a way to make Windows 8 delay loading the start screen until all startup programs have loaded?

Currently Windows 8 will get to the start screen a good 10-15 seconds before my startup programs have loaded. Since these include my touchpad driver as well as a gamma correction program, I would prefer that they would load before this point. Is there anyway to do this - either by delaying Windows 8 showing the start screen, or perhaps by somehow having these programs run before reaching the login screen?
