xs0u1x, after I analyze my C: before defraging it, under the System Health tab it says I have 122 Registry Errors and 70 Junk Files. When I click on the link "learn more" it takes me to a website to download Boostspeed. What is it and do I really need it? Also, it that the only way to clean up these registry errors and junk files? Thanks!
Whatever app that is, there are those that will fix errors automatically - they're pretty comprehensive PC clean apps. There's a slew of free ones such as Glary Utilities and CCleaner,
