Bloatware and outdated applications can be taking up an excess of hard drive space, and some of these programs run in the background upon startup whether you are using them or not. If you don't need the program, uninstall it. But remember, if you don't recognize a program name or know what it does, don't uninstall it until you've checked to see if it's software essential to running your PC.
