Everybody that uses Windows knows that from time to time we need to perform a major clean-up to remove unused junk in order to not only freeing hard disk space, but also to make Windows run faster and make our computer to run more stable. This tutorial is a step-by-step guide on how to make a major clean up on your PC.

There are several commercial software available on the market to help you out with this task. In our guide, however, we decided to only use freeware software and tools that come with Windows.

This tutorial can be applied to any Windows version. So, let’s do it.

1. Update your Windows by going to http://www.windowsupdate.com. This is pretty straightforward. Just open this address and click on the ”Express“ button that will show up and follow the instructions that will appear on the screen. The exact steps and the time it will take to update your Windows will depend on how badly your Windows is outdated.

A tip here is to enable your Windows to download and install updates automatically (this option only exists on Windows XP). Usually this is enabled by default, but you should check if your PC has this featured enabled or not. Just click on System icon on Control Panel and then click on Automatic Updates tab. Check if ”Automatic (recommended)“ option is select. If it isn’t, please select it, as shown in Figure 1.
