So my brother told me to download this program in order to clear up my computer. I tend to test out a lot of online games and try my best to clear them out when I get bored of them. I also have programs that have gone unused, unneeded, and unwanted on my computer. The list I have of programs to uninstall however doesn't seem to be quite as big as my C drive's program files folder. I have 105 GB Space and due to uninstalling my most recent games, I am still at 21.2GB free of the 105. After browsing the forums for a while as well as docs.piriform.com, I realized that I understand just about none of it. Now I know that I don't need my hard drive to be 4/5 full, which also the increase in random programs I am sure also slows down my computer a lot. My question is basically, how do I setup CCleaner to remove unused documents, folders, and program files on my computer. Such as the ones that came with the computer that were all not needed. I would like to have my computer running much better then it is. I cant even restart without it taking a century to close only god knows what. Also it has a tendency to say a program is not responding when it actually is but is just taking a little longer then normal. This wasn't an issue when I got the computer so I know it needs some work. I am running on windows vista currently and can provide any other information that may be needed. Thank you for your assistance!!
