Update: Adobe has clarified its statement below.
Most Creative Cloud applications receiving updates in the next major release will still support Windows 7. It is only Adobe video and audio tools that aren’t supporting Windows 7 – Lightroom and Photoshop will still support [Windows 7].From Adobe:
As we prepare for our next major release of Creative Cloud, we wanted to share some information on updated operating system requirements. To take advantage of the latest operating system features and technologies, the next major release of Creative Cloud will not support Windows 8.1, Windows 10 v1511 and v1607, and Mac OS 10.11 (El Capitan). For more detailed information about operating system requirements for the next major release of Adobe video and audio tools, see this post.
If you’re running Windows 8.1, Windows 10 v1511 and v1607 or Mac OS 10.11 (El Capitan), you can continue to run and install current and previous versions of Creative Cloud applications. However, you will not be able to install or run the next major release of Creative Cloud unless you’re on a supported version of Windows or MacOS.
Creative Cloud Desktop, which manages application installs, will continue to be supported on Windows 7 or later and Mac OS X v10.9 or later.
Focusing our efforts on more modern versions of Windows and Mac operating systems allows us to concentrate on developing the features and functionality most requested by members, while ensuring peak performance that takes advantage of modern hardware.
