In Windows 10 V1903 or later, you get Reserved storage feature, which will help you for smooth functioning of your system. Learn more in this post.

Recently, Microsoft released Windows 10 V1903 aka May 2019 Update with many new features. One of those newly added features is the reserved storage ability in Windows 10.

Till now, in the absence of reserved storage, if users fills up the storage, some apps, features will not function as expected. This won’t be corrected unless users clears up the storage to provide room for apps and Windows features. With the implementation of reserved storage, Windows will set aside a considerable amount of storage space which it will use system functions. So in this case, if user’s storage is reaching limit, there will be no effect on Windows features and apps functioning and reserved storage feature will handle it automatically.

Reserved storage is influenced by two factors. First is the optional features, and second is installed languages. When you add new optional features, Windows will automatically increased reserved storage accordingly. You can uninstall optional features and this will reduce size of reserved storage. Same logic applies to installed languages and you can add/remove them to increase/decrease reserved storage capacity, respectively.
