How to Turn on Reserved Storage in Windows 10

Today, in this article, we will discuss how to turn on Reserved Storage in Windows 10. Earlier Windows update fails to download new update packages when the disk storage was completely filled. To solve this problem, Microsoft has bought a new trait. This will be an inbuilt feature of Windows Devices that come pre-installed with May Update i.e. 1903. It is even applicable if you execute a clean installation of Windows 10 to your system.

With Reserved Storage, 7 GB of disk storage is retained only to solve the System Update issue, cache accumulation and apps related trouble. When a new Windows Update is available, existing files will be removed on the reserved storage thus allowing updates to occur instantly. For those who do want to have this attribute without setting their PC anew, there is a way to enable Reserved Storage on existing versions. Here is how to turn on or off this feature.

    I am not clear about how this will affect my ‘small storage’ 2-in-1 Tablet PC after the April update. Will Reserved Storage be implemented automatically? What will happen if there is less than 7 GB spare? Is the Reserve kept empty until it is required, or can files be saved to it and if so will they be overwritten by future updates, temporarily or permanently. In which case they need to be expendable – yes? Does Reserve Storage have to be on the C drive or can it be on an external drive and if so how will this be arranged. If it can then it does not present a major issue, instead of a can of worms.
