Microsoft has changed the storage device requirements for installing the operating system.
Now, in Windows 10, starting from version 1903 (this update is expected in May 2019), the minimum required free disk space for the operating system to function is at least 32 GB for both 32-bit and 64-bit versions.
Thus, Microsoft's 'Reserved Storage' of 7 GB was just the tip of the new operating-demanding iceberg.

Throughout this specification, all requirements for Windows 10 for desktop editions also apply to Windows 10 Enterprise.
Last year (Windows 10 version 1809 and earlier) the minimum was sufficient at 16 GB of disk space for 32-bit Windows 10 and 20 GB for 64-bit Windows 10.
Although the basic requirements already had more elevated disk space requirements

Thus, changes are coming in Windows 10 May 2019 Update as well.

Microsoft has not commented on this change regarding the minimum storage size to 32 GB.
However, many users have complained that even 32 GB is not enough for the normal operation of Windows 10 version 1809, so we expect even new thresholds for system requirements after the release of Windows 10 May 2019 Update (1903).
So, with the release of the new version of W10, buying a new PC will be a recommendation from Microsoft.
