Hello,
Thank you for posting in Q&A forum.
Microsoft 365 is a comprehensive subscription service that includes Office 365, Windows 10 (and Windows 11), and enterprise-level security features. In Microsoft 365 E3 and E5 plans, Windows 11 licenses are included as part of the package. This means that users who subscribe to these plans can legally use the Windows 11 operating system without purchasing an additional independent Windows 11 license.
Windows 11 licenses are not independent licenses in Microsoft 365 E3 and E5 plans, but are part of the entire subscription service. This means that users can use Windows 11 according to the rights and features of their subscription plans without having to purchase an independent license.
In addition, for those who have already subscribed to Microsoft 365 and use Windows 10, they can upgrade to Windows 11 for free, because Windows 11 is the successor to Windows 10, and can be upgraded through Windows Update if the system requirements are met.
I hope the information above is helpful.
Best Regards,
Yanhong Liu
