If you fell that you PC ist starting too slow or is running too slow, then you should try InControl. It's a very clear and simple startup manager. It gives full control on any application that is active or not. You can run them, stop them or even disable or remove them. If you have problems with some applications you can introduce them in the black list. Besides the control on all the startup programs, you can heal your PC by cleaning-up non working startup items, fix applications paths or remove broken uninstallers. If you don't know where are located, you can direct access some Windows features like services, registry editor, disk cleanup, system information, display loaded drivers, etc. The history viewer lets you return to a previous state of your startup, if you think that you did some mistakes.
