Re: It is beginning to happen
"As a Computacenter employee working on a major customer site, it is beginning to happen for real. Important parts to note is that enterprises DO have full control of updates, so the buggy anniversary update is typically not on the table to be deployed at present. And I imagine many future updates will be deployed only following a delay and some additional testing".
There might indeed be some tolerance of Windows 10 when it comes to larger companies that can afford the licensing costs of the more tame and controllable enterprise edition of Windows 10.
However, there will be many small and medium sized business that cannot afford that option and that cannot take any risk with the domestic version of Windows 10 with all its foibles. In this instance, these businesses are more likely to cling on to Windows 7 for as long as possible or move over to one of the unices (OS X, Linux, Chrome OS).
