A very quick look on the net reveals very little detail about the install process. It's a 3GB down load. Does it save as an ISO? If I want to do a re-install do I need to pre-install W7 then upgrade to W10? What happens to this upgrade offer if I decide to re-install after it expires. What happens if I want to setup a secure non-internet connected PC?
Has it occurred to you that your having a secure non-internet connected PC is something TPTB (and their useful tool Microsoft) strongly wish was impossible. So rather than waste time coming round to your place with a SWAT team, they just make it ever harder to do.
Why wouldn't a billion dollar company who no doubt hire more marketing psychologists than programmers not understand that installing a new OS is more important to some than choosing a flatmate that isn't a psychopath?
Why do obviously very intelligent people such as yourself seem to have steep psychological barriers to recognizing the clearly hostile motives of a company pushing an Operating System that with each version becomes a closer equivalent to sharing a flat with a psychopath? Normalcy bias, much?
The buildings full of marketting psychologists are only there to model exactly how far and fast MS can push their bullshit without causing any effective customer backlash. (Where 'effective' would involve razing MS offices to the ground and salting the earth they stood on.)
Someone earlier pointed out that MS just auto-installed an advertisement for Win 10 on everyone's PCs, disguised as an important security update. (On the PCs of those who have auto-update enabled, anyway.)
And you think you can trust this company with the digital shade of your life?
"Oh, but they are giving it away for free!"
No they are not. Microsoft is a predatory corporation, with only two interests:
1. Profit. Maximizing of it, without any moral considerations whatsoever.
2. Long term Elite-driven socio-political goals, which are quite complex but definitely not for your benefit.
I've read that MS has decided to switch to a 'rental model', in which they have sufficient control over the PC platform to be able to enforce perpetual and inescapable pay-for-use. The idea is that you won't buy the OS or utilities like Office, but rather pay a subscription for use of cloud-based software and storage. The 'thin terminal' model, in which your PC doesn't have much grunt, and is more under Microsoft's control than yours. Also all your data files will be 'safe and secure in the Cloud.'
And if you believe that is a good thing, well... you're going to have an interesting learning experience over the next few years. Also, anyone who thinks storing personal data on corporate cloud servers is in any way private, deserves an education via two by four.
Hence the 'Free upgrade to Win 10' hype. You know those cage traps used to catch animals? Like that. The cheese is free.
As a general prediction, I'd bet once MS feels they have an acceptable portion of the PC userbase shifted to Win10 (and the UEFI 'secure boot' scheme continues morphing into a fully OS-locked closed hardware platform) it's going to become virtually impossible for anyone but an extreme expert to revert back to independent, stand-alone operating systems. (He says, while having some typical difficulties just installing XP on a nice HP-Compaq 6910p laptop, from not too many years ago.)
Incidentally, somewhat relevant - a few days ago I discovered a forum for those seeking an escape path from the Microsoft Trail of Tears. Seems very active, with lots of interesting stuff. I'm hoping to finally try setting up nLite.
Microsoft Software Forum Network (It's _about_ MS software, not by MS. Especially optimizing non-current MS OSs like XP. And use of nLite.)
http://www.msfn.org/board/Oh, and while creating an account I found that somewhere between their server and optusnet, there's an email block. Multiple signup verification mails from them to me just vanished. But when I had the mails routed via my own US webserver, they got through immediately.
In my opinion, having their name on a blacklist somewhere is a very positive sign. They must be doing something right, enough to annoy our masters.
