An ounce of prevention is worth, what, a working version of your operating system? A few hours of a Windows reinstallation? All of your system's data? When it comes to dealing with issues with your PC, apps that help you prevent problems before they occur are worth their file size in gold.
A clean, efficient, and smoothly running PC only makes your life that much easier as a user: Your data is organized and accessible; your operating system is free of errors and other third-party problems; your system, well, works – and it works nearly as well as it did the first day you installed the OS.

This app does just what its name implies: It copies all of your system's drivers to a single folder for safekeeping, which you can then use to restore your system hardware to a workable state post-Windows reinstallation!
Let's face it: CDs and DVDs are going the way of the dodo. They're extremely prone to annoying scratches that can render them unusable, they're slow to use, they have a good tendency to be misplaced and squashed around the general messiness of your desk – the list goes on. WinToFlash saves the day by transferring the contents of your Windows installation disc to a flash drive, which the program then makes bootable. Provided your motherboard supports flash-based booting, hello speedier Windows installations!

Stop us if you've heard this one before.

Simply put, weekly scans with this app will keep your PC (mostly) problem-free!

But if you're looking for a tool that offers a bit more power than the standard Windows 7 disk defragmentation utility, Auslogics' Disk Defrag is your ticket. We especially enjoy its auto-defragmentation mode – scheduled defragmentation can be so easily forgotten!

And, yes, as the name implies, Syncback can do more than just copy folders, filter files, and schedule backups – it can also automatically match the contents of two folders to one another (the "synchronize" bit). This app is so slick, it almost makes us want to spring for the paid-for version!
Good ol' Belvedere – yes, this app really is like having a virtual butler for your desktop system. It's a simple tool that allows you to reconfigure and resort folder contents based on rules you specify. For example, you can sort all files in a folder matching a particular extension that are more than, say, 7 days old into a new folder called "archive." Or if you're hardcore, you can have this app delete these old files (or any kinds of files you specify) with but one click of a button!

Cleaning house is that easy!
For a bit more oomph to your system cleaning, check out DrivePurge. This freeware app almost offers too many choices for novice users to comprehend. Just how many, you ask?
