Not Yet
Thanks to the many posts on El Reg, I have deferred W10 until a reasonable release. Also thanks to those who point others towards GWX.
I've been watching the update stuff and so far haven't seen a W10 installer either as non-crtical or critical update.
I had the notification icon for months (now removed) and despite world+dog appearing to have the beast delivered I seem to have been forgotten.
I still don't trust the buggers and expect to have to spend a while digging around unticking boxes eventually in various 'security' and 'personalization' sections.
