Updated a couple of custom built machines, turned off all snooping options from the privacy screen.
First impression, it seems it's not happily using an insane amount of CPU cycles for telemetry or other mischief.
On earlier version of Windows 10 one of those machine could not come back from sleep without crashing, it seems that got fixed somehow. It would also wake from hibernate for no apparent reason. That too seems to be fixed.
Happy customer here.
