9. Remove programs that are unnecessarily loaded when Windows is started. You can do this using RegSeeker, clicking on Startup entries. This program will show you a list of programs that are run whenever Windows is loaded. Here you have to pay very close attention to not delete any program that is really necessary for your PC to work correctly (e.g., your video card control panel). Select the program you don’t want Windows to load automatically anymore and hit the Del key.
