As Microsoft continues to move towards the “Windows as a Service” model they recently released Windows 10 as a part of the Cloud Service Provider program which makes Windows 10 available for organizations of any size as a monthly subscription, in addition I considered this another opportunity to increase the adoption of Windows 10. Espcially considering Enterprise features such as Credential Guard and AppLocker are almost becoming mandatory for sufficient protection of Windows with the increased threat landscape.
The biggest disappointment with this license is that it requires an activated Windows 10 Professional License prior to activating, which means it can not be used for a cheaper upgrade to Windows 10. It also doesn’t include Software Assurance which I consider one of the bigger benefits with Enterprise license.

Microsoft will likely introduce a new license called “Windows 10 Enterprise E5” which will include Windows Defender ATP, if Software Assurance will be a part of this E5 license is currently unknown.
Considering the deprecation of some Group Policies in Windows 10 Professional prior to the launch of this license it could seem like Microsoft is trying to force organizations to use Enterprise license, sources in Microsoft confirmed this is not the case and Professional will still be usable for business in the future.
