We Have a Release Candidate

Posted on March 22, 2019 by Paul Thurrott in Windows 10 with 21 Comments

Windows 10 Anniversary Update Set for August 2 Release

Microsoft may not like this term anymore, but with Windows 10 19H1 build 18362 heading to the Slow ring, we now have a Release Candidate (RC).

“Hello, Windows Insiders,” Microsoft’s Dona Sarkar writes in an update to Wednesday’s post about build 18362. “We have released Windows 10 Insider Preview Build 18362 (19H1) to Windows Insiders in the Slow ring.”

That, combined with the fact that Microsoft had just released build 18361 only a day prior, is all the evidence we need: Microsoft has completed development of Windows 10 version 1903—aka 19H1—and is just trying to reach a level of quality where they can sign off on it. In other words, it has reached what we used to call the Release Candidate phase, where the current build is literally a candidate for release, or what used to be called RTM (Release to Manufacturing).

These days, of course, the manufacturing, such as it is, is all electronic. And Microsoft will, as it always does, update the code post-RTM in the weeks leading up to General Availability (GA). A term that Microsoft, curiously, is still using.

To be prudent, I’m holding off on a Magic Window post. But I think we’re almost there.

    I'm definetly waiting for that 'magic window' post ?

      In reply to Maciek:

      Speaking of magic window, there is a toggle switch under Windows Insider Program settings in Windows Update in 1903 under Stop getting preview builds which says: "Opt this device out of flighting when the next major release of Windows 10 is installed" Which one can toggle when the magic window happens. That should opt out of insider builds.

        Interesting...

        Microsoft should offer this option and publicise it. The game playing where people have to guess when to hop off being a tester is an entirely artificial construct.


        I don't have 1903 myself. Can you post a screenshot? Paul, does this option exist on your PC, and does it do what it sounds like on the tin?

    18343 is still showing up in the ISOs, with no option for '362.


    Can't they get this right?

  3. Alastair Cooper

    It seems that the option to defer for more than 7 days on updates is still gone from Pro.


    I'm *hoping* that maybe this is just an Insiders thing.


    The irony is I've never really needed it. But what happens if/when an update that does cause issues for me comes along?

    Oh boy am i glad to have a enterprise license through my company and thus have almost full control over my system when it comes to updates and when they are installed . A full system upgrade twice a year is just insane on a production machine. Come to think of it, its insane whatever machine youre running. On going releases of security patches? Absolutely, but this is just ....well, insane.

    Meanwhile, what ever happened to Sets?

    I'm stuck on build 18334. All later builds fails...

    Well, from past experience, Microsoft will sign this thing off whatever level of quality it's at just to hit a March/April release. I'd say, expect the first cumulative update within a week of release.

    Is it a release candidate if the anti-cheat software bug is still there? Does that mean it is on the vendor of that anti-cheat software to issue a fix and Microsoft has nothing to do with it?

  9. madthinus

    Very interested to see how they roll out this one.

    I'm waiting for the "gold master" - yes, I am that old.

      I go back far enough that I used RTC as a ship term in my Microsoft days.


      For those not that ancient, that stood for Release To Canyon Park. Microsoft at the time had their floppy disk recording and package assembly facility in Canyon Park, Washington.

    I await your word on when the Magic Window has commenced. It's very helpful in my getting ready for updating our custom builds. I never had any issues with past feature updates, when installing the freshly minted ones in new machines. Thanks for your vigilance, Paul.

    The link to Dona's post is the one for 18361 instead of 18362. Confused me for a moment as I couldn't figure out why they would release a build to the slow ring with a known serious bug. :)

    I just submitted a long feedback report about the unreliability connecting to wifi networks and Windows 10 fast start. This is a major issue for those who travel - Windows 10 has become very unreliable and slow connecting!

    whoops. looks like build 18362 is temporarily pulled from the slow ring for insiders who had build 18356.16.

    users who have build 18356.16 cannot upgrade to build 18362 and MS is developing a fix for it
