Every time you purchase a new computer it comes with software installed on it. Companies like AOL and Microsoft add on trial versions of their software, but what do you do with it after the trail is up? Or if you don’t ever want to use it how to you save the space on your precious hard drive? Removing these type programs is often difficult because they have several little bits that are stored all over the place on the computer.
If you run a Mac, don’t think that you are immune to these things. I have removed up to 2 GB off my mac that was just useless language files. Either way, mac or pc, I have found programs to help get rid of these useless programs and create more space so that your computer runs quicker.
