Windows 10 offers you the option to revert your system to an earlier build, if you face problems after upgrading your system to the latest build. "Builds" in Windows 10, are like the "Service Packs" in previous Windows versions and in fact are major OS revisions.
In Windows 10 you receive "builds" via Windows Update and these builds contain many fixes and improvements for your installed Windows version.
