Two things are included that M$ does not, extra updates and pre-installed things like dotnet 3.5 (which I still don't understand why it needs to be downloaded after) and all major updates up to the month of compellation. Less work/time and without needing internet.What is the difference between the "torrent" version of creating an ISO, and the one created following the MS process to create a "clean" ISO?
Both take as long as it takes based on the download capacity you have. both need to be installed ?
Also these are ISO's that contain more than one version of Windows which means you can use a single ISO to update/install many PC's in a variety of versions without needing internet (in this case both home and pro) instead of having to re-download the damn thing for each one separately. We don't all have fibre you know.
