The free upgrade limits flexibility with regard to imaging rights and deployment options. While a lot has been made about the free upgrade Microsoft is offering to Windows 7 and 8.1 users, the fact is that Windows 10 Enterprise contains greater benefits for enterprise customers.
Windows 10 is available as a free upgrade for Windows 7 and Windows 8.1 devices, however Windows Enterprise is excluded from this offer, and Windows Enterprise customers will require active Software Assurance (SA) to be able to upgrade. Windows 10 comes with a consistent user experience across all form factors, tighter integration with other elements of the Microsoft Ecosystem, and brand new features like Microsoft Edge browser and the voice activated “personal assistant” Cortana. Microsoft say Windows 10 is the last version of Windows that they will deliver as Windows is moving to an “as-a-Service” model where all new functionality is to be provided via updates, rather than new versions. Windows 10 is now available to Microsoft Volume Licensing customers.
