"it is best to turn off the automatic update"
You can't actually do that. However, it is now possible to delay feature updates for up to a year and quality updates (including security improvements) for up to a month. The feature updates have been the most troublesome
and least useful for me, so I've delayed them for four months to allow me to check content and the user reaction. The quality improvements I've left at 0 days delay because of the security implications.
I don't think this delay option was available in the original Windows 10. It's a welcome addition that should have been there from the start.
Also, if Microsoft is going to mess around with users' personalization settings, they should at least give notice of that and issue a list of settings that are likely to be affected. Windows 10 is the most difficult version to personalize because of the
cut-down personalization system, and I've been losing hours fixing things after every "feature" update.
