I just want to clean my computer off so it will generally run faster. All the programs I do not use anymore I want totally gone, and I find when I uninstall things from the control panel, the files and folders are still in my Program Files folder. I know to perform defrag, error checking, and virus scans, but since my C drive is getting full, I need to clear a bunch of stuff off so its like semi-new and runs faster. Any suggestion on how I should do this?
