Today is the first time Microsoft is providing this information.
Azure AD Premium is a paid service, available separately for $6 per user per month; most commonly, it's obtained through a license to Enterprise Mobility Suite (EMS), which includes Azure AD Premium as part of the package.
New apps are being designed for Windows 10, so if you have an older system, you might find yourself shut out.
Microsoft promised last October to become more transparent about the updates it provides for Windows 10.
CheesusCrust has plenty more surprises in store for Windows 10 users when he will publish part 2 of his analysis. As the incremental increase in build number suggests, this is a cumulative update to previous releases from the Threshold (TH2) development branch; newer builds from the Redstone branch are now available only to those on the Windows Insider Program. In doing so, those who have set their machine to automatically get important updates will get Windows 10, too. Michael Niehaus, director of product marketing for Windows at Microsoft, pointed to both resources in this Microsoft blog post.
To coincide with Patch Tuesday - the day Microsoft's monthly security patches are released - Microsoft is also creating a Windows 10 update history site. The update that arrives for an organization will depend on which service branch they are using.
Microsoft can also encourage app makers to write more software for Windows 10 if a lot of people are using it. It's similar to how Apple pushes its users to upgrade to the latest iPhone and Mac systems. The site will be updated concurrently with new updates, as they are made available, they said. Only the "long-term servicing branch" option permits traditional update deferrals by IT pros, but Microsoft sees that option as only being used for Internet of Things device-management scenarios. For instance, the first bullet states that Microsoft "fixed issues with authentication, update installation, and operating system installation", although no other details are provided.
The new history page doesn't use Microsoft's servicing branch nomenclature.
Update KB3135174 is for systems using Windows 10 version 1507 (the July update of Windows 10). Plus, I love the way Windows 10 looks compared to 8/8.1.
The July initial launch branch (build 10240), and the November update branch (build 10586). That's really very obscure (and confusing) information, but it's missing in the main Windows 10 history page.
The site lists key improvements in each update, along with their rollout date and identifier.
