Reserved Storage disabled on Windows 10

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

Reserved Storage usually will reserve around 7GB of storage for updates, temporary files, system cache, and apps. When a new update is available, Windows 10 will delete the files on the reserved storage automatically allowing updates to install successfully.

The new feature will come enabled by default on devices that come pre-installed with the May 2019 Update, or after performing a clean installation of the operating system, and if this feature isn’t for you because your device has limited space or you don’t like the feature, there’s a workaround to disable it modifying the Registry.

In this guide, you’ll learn the steps to disable Reserved Storage on Windows 10 version 1903.
