Re: Time, gentlemen, please
You forget, Microsoft have past form here with GWX Nagware updates. They can't be trusted to do the right thing on this.
As a person/org that strenuously spent an awful lot of time and effort to never install the GWX updates with Win7 updates set to choose/manual, I can tell you the number of attempts to install such GWX updates by Microsoft re-issuing the update(s) is close to 20 attempts. Even after the GWX campaign finished, these updates still showed up/are still being attempted.
Seems very odd behaviour for a Company if all the update does, is prompt users to install Win10.
Let's call it for what it is, Nagware is Malware by any other name, just because it's Microsoft doesn't make it acceptable.
