Microsoft has changed the storage requirements for operating system installation.
Now, in Windows 10Starting with version 1903 (this update is expected in May 2019), the minimum amount of free disk space required for the operating system to function is at least 32 GB for both 32-bit and 64-bit versions.

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) required at least 16 GB of disk space for 32-bit Windows 10 and 20 GB for 64-bit Windows 10.
Although the base requirements already had more inflated disk space requirements
So in Windows 10 May 2019 Update: Changes are coming 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 operating system Windows 10 version 1809, so we expect more new system requirements after the release 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.
