Understanding Microsoft 365 vs Office 2026
Before starting, it’s important to understand the difference:

     Microsoft 365 is a subscription-based service that provides access to apps like Word, Excel, PowerPoint, Outlook,

     Office 2026 (standalone version) is a one-time purchase. You get a fixed set of features without ongoing updates.

Your installation process is similar for both, but activation differs slightly.
