How to repair Windows 10 using the Media Creation Tool

Whether Windows update is broken, the Microsoft Store won’t open or your OS for whatever reason has gone corrupt, doing a repair install is your best option short of a complete OS reinstall from bootable media. A repair install sometimes called an in-place upgrade will download a fresh copy of the latest version of Windows 10 and install it right over your old install thus repairing all broken Windows components without touching programs or files.
