Windows 10 Fall Creators Update is already here, and you might have already upgraded to this latest stable version of Windows 10. After upgrade, you may experience low disk space as the upgrade process keeps a backup of the previous version of Windows.
If you are on low disk space, you can forcefully remove the previous version of Windows by following the steps mentioned in this article.
To begin with freeing up the disk space, utilized by the Windows backup version, open the Windows 10 Settings app and click on the System tab, as shown in the following screenshot:
Now, from the System tab view, navigate to the Storage page. At the right side panel, scroll down to Storage Sense and click on the link labeled Change how we free up space.
From this page, you can also ask Windows to automatically free up space by getting rid of the files that you don't need. This includes temporary files and the files in the recycle bin. To enable it, toggle ON the switch.
In the Storage sense settings page, as shown in the below screenshot, navigate to the Free up space now section and select the option that says Delete previous versions of Windows and click Clean now button.
This will force the system to delete the backup files from the previous version of Windows. If you don't do this, Windows will still remove these automatically after 10 days from the date when you installed.
This is to clean up the files which are not require any more as you have already settled your system with the new upgrade builds.
