Surprised that your customers upgraded to Win 10. I think most business users didn't do it, because they were afraid of this kind of troubles.

Most business users that I deal with are\were happy on Windows 7 and skipped 8 completely. Any small operations with external IT that are replacing equipment are happily going for Windows 10 now, as that's what is being pushed by Dell etc. Any big operation with an internal IT dept (ourselves included) seem to be largely hanging on Windows 7 because they can dictate via volume licencing what gets installed, and it's a known quantity.

Until October...

They're going to bunched-up single update packages containing both "security" fixes, and "tinkering" and "actively buggering-up" updates, for Win 7 and Win 8/8.1 beginning October 2016.

No doubt they understand these business users' mind set, and they figure if they can take this away from them, that might be the last thing keeping them from drinking the Windows 10 koolaid.

I believe that WSUS will allow the "security" portions to somehow be separated from the rest of the junk in these omnibus packages, but it is not clear that each separate update will be defined and controllable even using that method.
