Installed programs as well as Windows itself have a habit of leaving a trail of junk files and registry settings behind as they go about their business. Part of this is due to poor programming practices and part of it has to do with how Windows was designed. Whatever the reason, these junk files, as they are called, need to be deleted so they don't interfere with normal operation of your PC. Microsoft provides a tool for cleaning up these junk files but there is a better tool called CCleaner. It is available as both a free version and a paid version, with the paid version offering a few more options. I'll let you do the research and decide which version is right for you. In this video we will look at how CCleaner can help speed up your PC by cleaning out those junk files and also streamlining the Windows registry file, which can also become cluttered by leftover junk.
