Microsoft has changed the storage requirements for operating system installation.
Now, in Windows 10, starting with version 1903 (this update is expected in May 2019), the minimum amount of free disk space required for the operation of the operating system is at least 32 GB for 32-bit and 64-bit versions.
Thus, Microsoft's 7 GB "Reserved Storage" was just the tip of a new operationally 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), a minimum of 16 GB of disk space was sufficient for 32-bit Windows 10 and 20 GB for 64-bit Windows 10.
Although the base requirements already had more inflated disk space requirements
Thus, changes are coming in Windows 10 May 2019 Update same way.
Microsoft has not yet commented on this change in the minimum drive size to 32 GB.
Although, many users complained that even 32 GB is not enough for the normal operation of the Windows 10 version 1809 operating system, so we expect more system requirements after the release of Windows 10 May 2019 Update (1903).
So, with the release of the new version of W10, buy a new PC - this will be advice from Microsoft.
