Obviously Microsoft itself realises this, because Windows 10 Enterprise is essentially a different product. In the spirit of sharing good luck, I wish you luck in finding any large corporate IT department that will adopt an OS as their standard platform without the ability to control exactly what gets updated and when.
The trick Microsoft seems to be trying to pull with Windows 10 is getting everyone else to be the beta testers for its enterprise customers. Commercially, I imagine that makes a lot of sense if you can do it, since surely those enterprise customers are far more valuable to you.
Other customers, who can choose from ever more alternatives for activities that used to use a Windows PC by default, might not be so keen. Casual home users rely more on alternative devices like phones, tablets, and consoles these days. "Prosumers" and small businesses can work with Apple gear or Linux, either on their own merits or simply because if a lot of the services you use are available online then it doesn't much matter what OS you're running locally anyway. With Windows 10 Pro being such an odd beast, I wonder how much longevity Microsoft's apparent strategy actually has.
