As already seen by various other posts, such as 8, Vista, and XP, there have been unofficial ways of getting support. If this is the case, would that mean we could install updates from Windows Embedded 7 or Windows Thin PC (both based on 7, but have longer EOL times, up to 12th October 2021), in a similar way that Server 2008 or POSReady 2009 provided updates to Vista and XP respectively?
