Pro and Business can hold off installing updates for 8 months (that allows testing and integration by IT Dep'ts...but then they have to install as well.
Okay, so businesses could be stuffed by updates going guts up, then? Like is that from the launch of Win 10, or per round of updates?
In either event, it seems to me that MS is taking the 'big stick' approach to everyone and forcing them into accepting things they may not want. When you cut through the glossing over "look at the great things we're doing for you", it's a form of bullying. Instead of being bullied for your school lunch, you're being bullied into eating a lunch that might make you sick.
Seriously, businesses with large or small networks are likely to shy away from Win 10 if enforced updates have the potential to lose them millions... and/or put them out of business. In fact, as much I like Win 10's under-the-hood improvements, I am not too sure now if I want to upgrade. I may do so on one machine just to see how things go, but I'll likely hold off on my other rigs until such time as I'm better satisfied that updates won't entirely bork them.
Still, I am not impressed or happy with MS' 'big stick' approach to this. The potential for wide-spread system failures is enormous. I had hoped the leadership changes at MS would herald in a new and better era of MS marketing and products, but alas, the evidence suggests the complete opposite... and it would seem I am far from being alone with this sentiment. The low level of satisfaction and complaints regarding Win 10 and MS continue to mount, with more people, such as myself, joining the chorus of discord every day.
Oh well, I have copies of Win 7 and 8 that I'm happy with, so it'll be no skin off my nose if Win 10 fails to please. Also, I've had a bit of experience with a few Linux editions and may even switch a couple of my machines to Ubuntu, Mint or RoboLinux, which allows for the installation of Windows programs and games.
