The filesizes & checksums listed below are relevant to the ENGLISH version (not English International) of WINDOWS 10 PROFESSIONAL x64 (64-bit) only.

Note that the Windows 10 MediaCreationTool creates the ISO locally (on your PC), from the components it downloads. The ISO it constructs will be a one-off construct,
and its hash will be different each time that you make an ISO using the MCT, so it's not possible to check the finished ISO against any known hash.

However, there are hidden official ISO downloads, no longer "officially" hosted by Microsoft, but still available for download directly from Microsoft servers,
by using either the WINDOWS ISO DOWNLOADER utility from HEIDOC.NET, or via a link at TECHBENCH BY WZT.
Originally, these Microsoft ISOs were on Digital River.

My ISO timestamps & checksums listed below are derived from these hidden official ISOs, that I downloaded.
