Microsoft has made it known there will be no .ISO file for Windows 8.1 available to the general public.
"Consumers" here really means any copies of Windows 8 that weren't purchased through Microsoft's Volume Licensing programs. So a small business with 20 PCs to upgrade, for example, will have to do them one at a time via the Windows Store – so that's 20 separate 3.5GB downloads.
The Windows Store is the only way for consumers (non-enterprise, non-IT Pro) to download and install Windows 8.1. No ISOs will be made available, so each device needs to be updated individually via the Windows Store.
Well, that is not very clever - it will only encourage downloading from alternative sources which then will be fraught with the risks of malware. Not to mention about those small operators who have 5 or 10 PC's that need upgrading but do not have sufficient broadband allocation for that amount of data. We're running Windows on MAC computers in Bootcamp but this may just tip us over to going OS X on all of them.
