Time for a test, I think...
Might have to do a test install of Windows 7 Professional SP1 on a separate SSD I have inside my computer tower.
I'll install Windows, then run Steve Gibson's Never 10 and/or Josh Mayfield's GWX Control Panel (I think they pretty much do the same thing although I've noticed Never 10 needs to download and install a more recent Windows Update Agent before it can do it's job).
Then, I'll install the rollup package and see what happens. I'll also run Spybot's Anti-Beacon afterwards and see if it still disables telemetry if it has been installed.
It'll be something to fill in time one evening when there's nothing worth watching on telly
