There’s an updated (July 2019) Windows 7 and Office 2010 End of Support FAQ. Use it to answer questions such as: which programs are the Extended Security Updates available in (currently EA/EAS/EES, but CSP too by the end of 2019); who’s eligible for free ESUs (EA/EAS customers with active Windows E5 or Microsoft 365 E5/E5 Security subscriptions); and in which Windows environments is Office 365 ProPlus supported (it depends, see pages 12/13).
