Windows operating system is a Microsoft Product. There are many techs who are trained on Microsoft certification and self learnt basis.
Microsoft changed it's Office 365 name to Microsoft 365 starting from April 21, 2020. Microsoft says "Microsoft 365 Apps simplifies the on-premises Office upgrade conversation by clearly differentiating on-premises Office from Microsoft 365 Apps. With Office 2010 end of service rapidly approaching and Windows 7 end of service already passed, users of these products should be encouraged to consider Microsoft 365 Apps."
