The Windows 10 updates I have noticed required a reboot.
There may have been updates which didn't which I didn't notice.
Patch Tuesday has gone.
Updates come out of the blue.
Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3124262) yesterday.
Microsoft have been saying for many years that they want to reduce the number of reboots.
I recall Gates allegedly saying that an update needing a reboot was a major bug.
I switched my 64 bit desktop back to normal updates after an insider update broke MediaMonkey, with it skipping every track.
My 32 bit laptop did not have the same problem, and is still on the insider program.
