Original Windows 10 to retire

As of 26th March, the support for the original edition of Windows 10 will come to an end.  Windows 10, version 1507 was released July 2015. Microsoft assigns year-month labelling to the Windows editions.

Written in a post to a company blog, Mr Mercer had said that “After March 26, 2017, Windows 10, version 1507 will no longer be serviced, as only the two most Current Branch for Business (CBB) versions are actively serviced.”

Back in November, Microsoft had warned customers that when it promoted version 1607 to the Current Branch for Business (CBB), it would end updates which includes security patches for 1507 during March. However, version 1507 will still continue to work, although after Saturday 26th March it will not receive updates.

This stoppage is an important part of the new software-as-a-service model which Microsoft has promoted for Windows 10. Microsoft has pledged to support only the two CBB builds all together, this means that at the release of N+2, which means N equals an earlier Version, Microsoft will start the 60-day or so countdown.

Once those 60 days ends, N will drop off the support list, then N+1 will become N and N+2 will move over to become N+1.

When last year’s Anniversary Update, which was labelled 1607 had been shifted over to CBB; N is equaled to 1507, N+1 is equal to 1511 (which was the November 2015 upgrade) and finally N+2 represents 1607. All of this means that 1507 support was due to be shuttered two months from the January availability of 1607 in the CBB.

Microsoft has also recently released a refreshed 1607 via Windows Server Update Services (WSUS) and Windows Update for Business (WUB), these are two the most common ways for enterprises to access upgrades.

On 26th January, the same CBB-qualified build will be issued to the Volume Licensing Service Centre (VLSC), which is where customers are able to download disk images of 1607. The VLSC availability date is used by Microsoft as the trigger for the 60-day countdown.

There are some company customers, who are already running 1607 this also includes consumers (those who began to receive the build, otherwise known as the “Anniversary Update” in August) as well as the businesses who have assigned Windows 10 devices to the “Current Branch” (CB) track.

Finally, on the Microsoft website, users are able to track the different versions of Windows 10 as well as the last-served updated for each version.
