On Dial-up? Out in the boonies somewhere? Wireless? How long will it take you to “upgrade” to “8.1” if you have been so foolish as to buy a PC with “8”? Got five PCs in the house? Download five times! Enjoy!
“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.”
I can imagine some of the schools where I worked running “Home” versions needing to download 3.6gB 50+ times just to get back to a “start” menu. It would be much easier to switch one machine to Debian GNU/Linux, perhaps just 2 gB of downloads, and copy hard drives. The licence allows that and GNU/Linux provides tools like dd, debian-installer and CloneZilla. How limited, small, tight, uncomfortable is the burden of that other OS on ordinary people. GNU/Linux will work for you just as it will work for IT-pros. No need to fly third class.
To give GNU/Linux a go, visit Goodbye-Microsoft.com or download an .ISO file to make a bootable CD or flashdrive. It’s easy to use a real operating system and applications rather than a sales-gimmick.
