Every time you use your PC it's storing temporary files, caching web pages and generally cluttering up the machine. Add to that the fact that as files are added and removed information gets scattered across the hard disk, entries get left behind in the registry, items are added to menus and to the system start up. It should come as no surprise then that eventually the machine will begin to slow down as it struggles to keep track of all this information.

Fortunately you don't have to accept this tailing off in performance. There are plenty of software tools available that can help you clean up the machine and tweak your system settings to put a spring back in your system's step.

Whether you want a general clean up of the system or need to target a particular area such as the performance of your hard drive these are some of the very best programs for the job.

In no particular order here are the top ten system tuning tools - Note the tools below are for Windows 7 and earlier versions of Windows.

1/ SimWare Utilities SlimCleaner

Price: Free

Web: SimWare Utilities SlimCleaner

SlimCleaner is a free tool that takes an innovative crowd-sourced approach to cleaning up your PC. It uses feedback from the user community to recommend the optimal settings for programs and services. You can clean up the system as well as uninstall unwanted software. It also lets you identify the data clogging up your drive and securely wipe sensitive information.

There's a useful hijack log that can help you remove unwanted browser add-ons and toolbars. In addition the program brings together standard Windows tools like Device Manager and Performance Monitor in one handy location.

You can run SlimCleaner from a USB drive making it a useful option if you want to scan several PCs as you don't need to have software installed on all of them. The community ratings for programs are shown on a colour-coded interface so you can see at a glance if a piece of software is good. Naturally you can add your own feedback to improve the ratings. Note that it adds a toolbar to your browser unless you opt out during installation.
