I have two identical laptops running Windows 7 Pro. A while ago, a “Get Windows 10” icon appeared in the system tray. It reports that my computers are compatible and has a “Reserve your free upgrade” button, which I have ignored as I am fine with Windows 7 and in no rush to change to Windows 10, although I may get it later, if/when it appears to be worthwhile and stable.
However, I was surprised to notice in the update history on one of my computers that an “Upgrade to Windows 10 Pro” failed on three consecutive days last week (error details: code 80240020). I gather this means that something has been deferred for some reason? …

… but now I am unsure whether my computers are going to be “upgraded” to Windows 10 automatically or not. Is there a way to make sure Windows 7 is not replaced with Windows 10 unless/until I choose?
