The first update/upgrade will be primarily, perhaps exclusively, for consumers, delivered to devices running Windows 10 Home by default via the Windows Update service. Microsoft is calling that update cadence or track "Current Branch" (CB), part of the new release lexicon the Redmond, Wash. company's invented.
Those running the more advanced Windows 10 Pro can also adopt the consumer-speed CB track. People most likely to do so are the power users, enthusiasts and work-at-homers with a Pro edition, as companies -- which also widely deploy the various Windows' Professional or Pro SKUs (stock-keeping units) -- will probably play it conservative and instead take updates from the Current Branch for Business (CBB) after they have moved to Windows 10 Pro.
Not everyone on CB will get the first update at the same time
Microsoft has provided some update flexibility (its take) or complicated matters (the cynic's view) by segmenting each "branch" into "rings." The latter is a second release timing mechanism that lets customers receive a branch's update as soon as the build is approved via a "fast" ring, or delay the update's arrival using a "slow" ring.
Rings on the CB were confirmed only this week by Terry Myerson, chief of the company's OS and devices division, and may number more than the two: Again, Microsoft's not elaborated.
Nor has it said how long the stretch will be between fast and slow. It may be weeks; it could be months.
The Windows Insider preview program, which will continue to run after July 29, has put devices into the slow ring by default; Microsoft may or may not do the same with the CB.
The one certainty is that not everyone on the CB will get the update immediately. "Some consumers just want to go first. And we have consumers that say, 'I'm okay not being first,'" Myerson said on Monday.
Most business PCs won't get the first update until the Spring of 2016
Because Microsoft will be using its Insider participants, and more importantly the millions of consumers running Windows 10, as testers, it will not release builds to businesses at the same time as those on the Current Branch.
With the four-month stretch between updates/upgrades and the automatic delay built into the Current Branch for Business (CBB), customers on the latter will not receive the first build until next year: On a strict schedule, that will be at the end of March or beginning of April 2016.
Microsoft's doing it this way, it's said, to produce more bug-free code to its most important users, businesses. Microsoft figures that the four months will shake out more bugs so that those running Windows 10 Pro or Windows 10 Enterprise will get a more stable update with a correspondingly lower risk of something breaking.
