Within the new version of Windows 10, Microsoft introduced a new feature called Reserved Storage. As you can tell in the feature name itself, Reserved Storage puts aside some quantity of space so that it may be used through the system to update and change your system. Additionally, the reserved storage can also be used for temporary files, system apps, and system cache.

The primary aim of the reserved storage feature is to avoid "your disk is full" or "low disk space" notifications while updating or upgrading Windows or any other system files and apps. If you do not like this behavior, you are able to disable reserved storage on Windows 10.

Just how much Space for storage is placed Aside for Reserved Storage

Generally, Windows puts aside around 7GB of your C drive space as reserved storage. However, based on your usage, Windows may choose to boost the reserved storage space.

Two major components that affect the size of reserved storage on Windows 10 are optional features and installed languages.

By default, most of the optional features are disabled. When needed, you can enable the optional feature you would like in the control panel or settings app. For instance, Windows Sandbox and Linux Subsystem for Windows are optional features and really should be manually enabled to utilize them. For the way many optional features you've enabled, Windows could raise the reserved storage space accordingly to correctly maintain and update those additional and optional features.

The same does apply towards the installed languages on your system. The more languages you put in in your system the greater space is put into the reserved storage to manage and update those language-specific files.
