As well-known Microsoft insider Paul Thurrott explains, this is a big deal, both for creatives who now have a choice of where to download their software, and for Microsoft, which seems to have struggled to get the Microsoft Store to take off in the same way as Apple's Mac App Store.
The Microsoft Store lives on
Earlier this year, Thurrott speculated that Microsoft's Unified Windows Platform (UWP) apps could soon be killed off, which would have left the Microsoft Store bereft of content and its future in jeopardy.
Those speculations have since proved to be unfounded (it appears that the forthcoming Windows 10X will support UWP apps, and Apple is hunting for a developer with UWP experience to create what may be a Windows 10 version of iTunes.
The support of a major developer like Adobe seems like even more proof that things are looking up for the Microsoft Store, and if it continues the store could become a genuine first destination for Windows users looking for premium software. It'll be interesting to see if any other major developers decide to follow suit, and whether the rest of Adobe's creative apps will appear on Microsoft's virtual shelves.
