Why Reinstall Windows?
Windows gets clogged up with old software, especially if you install, uninstall and reinstall applications frequently, which tends to happen a good deal when you mix an Internet connection and general curiosity. Uninstalled applications occasionally leave bloated "tools" installed and more often large amounts of data in the Registry, your system background can become weighed down with tasks that load silently at start-up, essential system programs can be forced to perform non-essential cycles induced by other installed/uninstalled software. It's hard to rectify all these problems through tweaking alone, and due to the way Windows was designed the best option is to simply start again. Viruses and spyware can also damage a system to such an extent that repairing Windows is not a realistic option and re-building from scratch is the only way to proceed.

A "Clean" Install.
We have established that reinstalling Windows will give your computer a fresh turn of speed, and can solve a myriad of software related problems. However this is only really the case if the reinstallation is a "clean" one and this means a new format of your hard-disc and the loss of all the programs and data contained therein.

Saving and Replacing your Files.
Replacing the documents that you have created, such as typed text, email, photos and music is usually not a problem. This data can be moved onto another storage device before installing Windows and then moved back to the system after the new install. Saving your contacts information, internet explorer bookmarks and other "settings" is not difficult providing you know how to do it, but it certainly isn't as easy as copying files and folders and many people simply forget to do it and it can be very annoying to have to start entering addresses and other information all over again.

Replacing the Operating System and Applications.
This is technically a simple matter but the procedure is often made complicated because of the "human factor" and a lack of understanding of what "installing" programs actually means.
Programs are not simply files in folders that can be backed up like documents and then replaced after the new install. Programs are "installed" and the installing is done by using a special "installer" programs which put a multitude of different files in different places. Special "keys" are also added to the registry; a process that is made invisible to users by design.

Reinstalling Windows: Understanding what I can and can not do.
Backing up your documents, photos and music really isn't difficult and can often be an automatic process providing you have a good "system" for doing so already in place. Unfortunately, so many have had to learn the "hard way". I can show you how to protect your valuable data and show you how to back up onto DVD or create an automatic process to preserve the whole contents of your hard drive. Unfortunately a Windows installation doesn't last forever. Have you ever wished that you could take a "snapshot" of your PC when it's in the peak of health and then simply return it to that state when needed? It isn't difficult and I can teach you how to do it.
