Have you had a program that starts whenever you log in to your account and you can't get it to stop? Well there is a somewhat painless way to make sure it does not pop up unless you activate it. All that needs to be done to do this is to first open up your "Run" window (windows xp is in the start menu, Vista+ is accessed by holding the windows button and pressing r, or you can search for it.) and then you type in "msconfig" without the quotes. This will open up the System Configuration and there will be a tab called Startup that will list all of the programs that start when you log in to your account. Make sure you only uncheck the programs that you know that is not related with how the computer runs. After you uncheck the programs you do not want to start on log in it will prompt you to restart or to continue without restarting and that's your choice if you want to check it right away or not.
I decided that if I think of something that could be useful I will just update it soon after the idea comes up. Updates will come faster if I have question in the comments.
