Does Repair Install download less if run from installation media?

Rackbrane · 25 Oct 2016

If I run Repair Install from setup.exe on USB, DVD or in an ISO image, does it use the files from the media, thereby downloading 3.2GB less than if I run it from the Media Creation Tool? I would be using media for the currently installed version 14393 of Windows 10 Home.

Is the outcome the same as I obtained when running the original upgrade from 10586 to 14393 (except that there will now be more updates)?

Hi,
1. Any form of upgrade repair install uses the same data as a starting point.
2. Not more updates, but a growing cumulative update.

The cumulative update does not necessarily grow as stuff often gets replaced in favour of later updates.

After starting though, does it download all the Windows base files again, or use the base files from the media I provide? If it uses the media, then there will be around 3.2GB less to download.

If you run Setup from the USB, DVD or ISO image you created earlier then the files to install Windows will be copied from the media. Only updates will need to be downloaded.
