How to enable ‘Reserved Storage’ on Windows 10

You can enable "Reserved Storage" on existing installations of Windows 10, and in this guide, you'll learn how to enable, disable, and check the feature on version 1903.

Enable Reserved Storage on Windows 10

On Windows 10, Reserved Storage is a new feature starting with version 1903 (April 2019 Update) designed to set aside part of your computer available storage, which the system can use 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 April 2019 Update, or after performing a clean installation of the OS, but there’s a workaround to enable Reserved Storage on existing installations. (The changes will take affect in the next upgrade.)

In this guide, you’ll learn the steps to enable or disable Reserved Storage on Windows 10 version 1903, and you’ll learn the steps to see how much space the feature is setting aside.

Warning: It’s very important to note that modifying the Windows Registry can cause serious problems if not used properly. It’s assumed you know what you’re doing and that you have created a full backup of your system before proceeding.
