This simple freebie helps speed up your system by unclogging your hard disk. It finds duplicate files, cached files, and other excess items, and then deletes them for you.

Cleanup Assistant is free and easy to use, so even though it may not be the most sophisticated of programs, it's worth a shot.

Optimize for Speed

Eusing Free Registry Cleaner

One major cause of system slowdowns is a bloated Registry filled with out-of-date or bad entries. Your Registry gets junked up in many ways, notably when you uninstall a program that is ill-behaved and leaves traces of itself behind. As a result, one of the best ways to improve PC speed is to use a Registry cleaner or fixer. Plenty of for-pay fixers exist, but if you want just the basics, Eusing Free Registry Cleaner is a good bet. It scans your Registry for problems, reports on what it finds, and then fixes the problems you tell it to address. You can also restore your original Registry settings if the new ones cause problems themselves.

If you're looking for the ultimate free PC cleanup tool to help boost system performance, look no further: You've found it in CCleaner. For a start, it cleans out junk and unnecessary files in Internet Explorer, Windows Explorer, your overall Windows system, and many applications. It also includes a Registry scanner that hunts down and fixes problems, and it offers an uninstaller for removing unwanted programs. In addition, it deletes traces of your Internet activity to protect your privacy.

Auslogics Registry Defrag

Cleaning your Registry with a tool such as Eusing Free Registry Cleaner (see above) will go a long way toward improving PC speed--but it won't go all the way. Even after you scrub the Registry, it may still suffer from bloat, because over time the Registry becomes defragmented, particularly when you add and remove entries. The free, simple Auslogics Registry Defrag utility defragments the Registry and gains you a bit of hard-disk space. More important, though, is that it speeds up your computer's access to the Registry by compacting it--and that means a faster PC. The program is free, it's simple to use, and it revs up your PC...what else could you ask for?

Internet Boosters

These days, we practically live our lives online. If you're looking for a way to boost your Internet experience, check out these downloads.

MySpeed PC Lite Edition

It's tough to know whether your Internet connection needs a speed boost. That's where this useful program comes in: It measures your upload and download speeds, and then shows you where your results lie on a continuum of access methods, from a slow modem to a superfast connection. It will also graph your speed over time.

Just as useful, though, is its analysis, which provides more details and helps you understand what the speed figures mean. For example, if it measures your upload speed at 5.66 megabits per second, it will say that your speed is good for service rated at 6 mbps and reasonable for service advertised as 7 mbps, but poor if you're paying for 8 mbps or above. It will also measure your quality of service, which determines whether you can sustain your maximum transfer speed.

For best results, use this application's information to determine whether you need a performance boost, run another program such as SG TCP Optimizer (see below) to enhance your speed, and then run this utility again to see whether the tweaks helped.

Bandwidth Monitor 2

This nifty little free application won't actually boost your bandwidth speed, and it isn't as comprehensive as MySpeed PC Lite, but it will help you know whether any network-related speed tweaks you've made have helped performance. It tells you your current upload and download speeds, and provides a graph of the speeds over time. In addition, it provides a log of your activities, including the total amount of data uploaded and downloaded in a day.

SG TCP Optimizer

No matter how swift your broadband connection is, it's not fast enough. You can't get your ISP to juice up the bandwidth, but you can make the most out of what you have. This free program will tweak various connection settings to help you obtain a faster, smoother connection.

At first glance the program is daunting, because it seems to require you to know certain technical details, such as latency and largest MTU. Your best bet is to click the Optimal settings button at the bottom of the screen and then click Apply changes; that way, the program makes decisions on its own. Unless you're very experienced, you probably don't want to muck around with the settings yourself.

Keep in mind that the proper connection settings can vary significantly from PC to PC, so you could possibly change your settings and end up slowing your system down. Mostly, though, if you follow the app's advice you'll find yourself with a better connection.

This program promises to speed up your DSL or cable modem connection through what it calls "traffic shaping"--the prioritizing of certain data packets. You won't have to know anything about data packets or TCP/IP to use this utility, because it learns as you use the Internet, silently determining the best way to "shape" your traffic to boost performance. It then makes adjustments accordingly, and as a result you should see faster page loads and download times.

Note that the program can't improve your actual total bandwidth (that's something only your ISP can do); instead, it makes the most efficient use of your bandwidth so that you get an effective speed boost. The program also has some nice extras, such as a real-time bandwidth monitor.

Dedicated fans of file and media downloads face one frustration above all: slow download speeds. Though you can't increase your total bandwidth without?switching to a faster ISP,?you can download files more quickly by using the BitTorrent protocol, which is far?faster than traditional methods. When you use the BitTorrent protocol, you retrieve pieces of a file simultaneously from multiple locations, significantly speeding up downloads.

There's one problem with the BitTorrent client, though: It's not a particularly good piece of software. The solution is to use uTorrent, a superior client. You can easily search for files from directly within the program, track and manage your downloads, and create your own files to distribute via the BitTorrent protocol. Among other good features in the program are a configurable bandwidth scheduler and global and per-torrent speed limiting.

PDF SpeedUp

Few programs on the planet are more annoying than the Adobe Acrobat Reader. It's slow, it's buggy, and it seems to drag down entire systems whenever it's loaded. This freebie eliminates most of the program's annoyances, disabling the splash screen, killing the piped-in ads in the upper-right corner of the toolbar, turning off the invisible updates feature that sucks up RAM and system resources, and preventing plug-ins from loading, among other things.

Using the program is as simple as can be: Just click the Optimize button, and it does its work. To bring back your original settings, click Restore. You can also customize exactly which features it optimizes. The program works with versions 3 through 7 of Adobe Acrobat Reader.
