This tutorial explains how to free up disk space using Windows 10 Compact OS tool.

Compact OS is a built-in feature of Windows 10 which automatically compresses system files, footprints of Windows 10 apps, pre-added desktop applications, and help you gain disk space. The files are first put into a secret container and then compressed to free up the disk space. It can help you gain 2 GB or more disk space. The amount is not so big but yes it matters when the disk space is too low and you can’t uninstall programs for the time being.

In the screenshot visible below, you can see the difference before and after using this Compact OS tool. I was able to get around 2 GB of hard disk space. You can do the same. However, before you start using this tool, I would suggest you to take the backup of entire system to help you recover from any loss. Using this tool is safe, but it would be good to have a backup.

Note: After compressing system files using this tool, it might impact the performance of PC. For example, apps might open with a very short delay. However, if you have high configured PC, you won’t even feel if there is any performance loss.
