your not limited with wpi, your only limited by your own Enthusiasm, wpi can do every app out on the market, it uses the runonceex method, so all your programs will install its just up to you to be Enthusiastic enough to find ways to make the progs unattended, if they cant be done by a switch you can go the harder routes, autoit, custom build the installer, or use a simple basic program that reads your mouse movements,, but i owould only use that method as a last resort because it does lack a few what the other methods have and thats a true unattended method, but my friend each to their own best of luck
