I have a home, pro and enterprise Window 10 machines running build 10.0.10240 - All CLEAN BUILDS
One of the pro devices has automatically upgraded to build 10.0.10586
This upgrade took several hours and appears it used a similar 'in-place' upgrade to that used from W7/W8->W10, as I now see a windows.old folder and a chunk of hdd space used.
I'm reasonably happy to install the update, but I want it at a time that I choose (probably in a few weeks)
How can I block the other machines from upgrading automatically ? Does the upgrade show as a KB number in the windows update list?
I do not consider 'defer updates' to be good enough and I'm not keen to turn off all updates - I just don't want this massive update yet.
