Windows 7 end-of-life nag messages will start showing up next month
Found on Ars Technica on Wednesday, 13 March 2019
Starting next month, the operating system will show users a "courtesy reminder" to tell them that security updates will cease and that Windows 10 (and hardware to run it on) exists. Microsoft promises that the message will only appear a "handful of times" during 2019 and that there will be a "do not notify me again" checkbox that will definitely suppress any future messages.
Update reminders are well-remembered from the times when Microsoft tried to force everybody onto Windows 10; even against their will.
