The 20 (Mostly Free) Downloads You Can't Do Without

You likely have plenty of software on your PC. But do you have the right software?

Any well-equipped system needs a basic software suite, a collection of tools that can keep your machine in working order and help it take care of everyday tasks--as well as some not-so-ordinary tasks. Since such software doesn't ship with your PC, for the most part, you'll have to accumulate it over time.

Which programs should you get? We've put together a suite of 20 must-have applications--the tools that will allow you to get the most out of your PC. We've included a wide variety of software, from security utilities to system cleaners to graphics tools. We've mixed some all-time favorites with some apps that you've probably never heard of. They all have one thing in common: You need them. Now. So read on and start downloading.

System Boosters
First, here's a look at software that can help your PC run in tip-top shape, including a Registry cleaner, a system optimizer, and more.

Glary Utilities
If you need to clean and optimize your machine, improve your privacy and security, or do other similar tasks, you'll want this program. It's free, it's simple to use, and it'll make your computer run much better.

Its cleanup and repair tools include a Registry cleaner, a disk cleaner, and a shortcut fixer that corrects shortcut errors on your Desktop or Start menu. Among its optimization tools are a startup manager and a very good context-menu manager for editing the menu that appears when you right-click a file.

You also get a file shredder, encryption tools, a utility for cleaning up your Internet traces...the list goes on. For anyone who wants to take control of their PC and doesn't want to pay even a penny, this is a great program to get.
