It’s amazing the amount of stuff on a hard drive that can be overlooked, until you run out of space. The Disk Cleanup tool that is built into Windows can help keep your machine extra tidy, but can also be a powerful tool when you’re in a space crunch.
Think of the Disk Cleanup tool’s basic functionality as a “squeegee”. But it has a mode that deals with system level files and more important stuff; think of that as the “power washer”.
In “power washer” mode, I was able to free up almost an additional 29GB of disk space. A lot of this was due in part to the recent upgrade to Windows 10 that was performed on this machine. And there’s more to be saved too. More on that later.
I’ll walk you through the basics of how to use the Disk Cleanup tool. It’s pretty powerful, so if you’re worried that you might inadvertently clean up something that you shouldn’t have, make sure you backup your data first.
