Disk Cleaning - Part 1

This is the first part of How to clean and increase your computer's speed with simple things.
This part is about using the tool of disk cleaning. I'm using Windows 7, but it's the same thing for Windows XP and Windows Vista.

First, go to your Computer and select the disk you want to clean. (In my case is C:)

Then Right click on disk and it will appear a menu.

(My screen shots would appear in Portuguese, but it's the same option in every language)

And choose the option Properties.

Then click on the Disk Cleaning button.

After clicking on that button this window should appear, wait for it to finish calculating.

Now you choose which items you want to clean or erase. And click OK

Now just let it finish the job and you will see that you will have more space on the computer to use
