Up until now, if your Windows 10 PC’s system drive (the drive where Windows 10 is installed) is running out of disk space, you had no option but to manually free up disk space by deleting temporary files and uninstalling programs. Starting with Windows 10 Creators Update (build 15014), Microsoft has introduced in a new option to automatically free up some space on your Windows 10 PC by deleting some temporary files as well as older files in the Recycle Bin. At present, the automatically free up disk space feature deletes temporary files that your apps are not using and also Recycle Bin files that have been there for over 30 days. Although this feature is not as powerful as some third-party utilities out there, Microsoft is expected to add more temporary file locations and more options to this automatically free up disk space feature. The new feature, for some reason, is turned off by default. You need to turn it on under Storage section of Settings app. The addition of this feature not only makes PC maintenance easier than before but also helps novice users free up disk space without any worries.
