First, before you start, make sure that you have a backup of your computer and data, as following these instructions could delete everything from your computer. This is because the upgrade doesn't refresh the files that Windows needs to restore factory default settings - annoying, huh? Fortunately, Microsoft has made it fairly straightforward to download and create your own Windows 8 or Windows 8.1 installation discs, so that you can get round this step.

While it's generally a very easy thing to do, the utility can run into problems if you upgraded from Windows 8 to Windows 8.1. With Windows 8 things are a lot easier and the ability to wipe your computer back to factory settings, or simply refresh the install leaving your files alone, are built directly into the operating system. With Windows 7 and before, doing this would require a fresh install or using the manufacturer-provided disc image, which is a cumbersome and long-winded process. There are plenty of good reasons to wipe your computer and put it back to its factory default settings, including selling it and protecting your private information and simply clearing out the clutter.
