On Windows 10, Reserved Storage is a feature designed to allocate part of your device available storage for updates and upgrades to avoid problems as a result of not enough space.

The feature has been available since version 1903, and it comes enabled by default after a clean installation or on newly manufactured devices.

Starting with version 2004, Windows 10 is introducing new commands for the Deployment Image Servicing and Management (DISM) command tool, which allows you to determine if Reserved Storage is configured as well as to enable or disable the feature.

In this guide, you’ll learn the steps to enable or disable Reserved Storage using the DISM commands on Windows 10 version 2004.
