Windows Threshold development hits Windows NT 6.4

Microsoft is currently developing the next major version of Windows, currently known as Windows Threshold or Windows 9. We’ve been tracking development via a user on Twitter, who constantly watches app logs to check for new build numbers. Today, Stealth2013 has spotted the first Windows NT 6.4 build, which means Windows Threshold is going to bring yet more improvements to the NT kernel.

Today’s build is 9788, and other than the NT version number we don’t know much else about the build. These are not full build strings sadly, which means we are unable to determine when the builds were compiled or what lab they were compiled in. What this does tell us though is that Microsoft are constantly compiling new builds, and that even more kernel changes are in the pipeline for Threshold.

Much like every major version of Windows, the NT kernel is usually bumped by x.1 or even a whole version. The jump from Windows XP to Vista saw the NT kernal rise from 5.1 to 6.0. Windows 7 was 6.1, Windows 8 was 6.2 and Windows 8.1 was 6.3, so Windows Threshold could have either been 6.4 or 7.0. It seems Microsoft went for the minor bump instead of the larger increase.

We recently heard about how Threshold was going to act for both desktop and tablet users, with a Start Menu taking center stage for users without touch, and an improved Start Screen for tablet users. We’ll update you accordingly when new Threshold information arrives, so stick around at WinBeta until then.

    I wonder why Microsoft didn’t opt for a 7.0 release?

    • yannick

      Has been said here quit some times, a jump for the major version number would result in Windows Vista 2.0. An aweful lot of software, especialy drivers, checks for the first number, if it doesn’t match, it won’t work, even if the driver would work without this check. That’s one of the reasons Windows Vista faield.

      • Zac Bowden

        I’m worried we’re going to have another OS X problem. Anybody up for NT version 6.11?

        • Sargon

          I like that they’re not rushing to 7. If Windows 9 will be loved (and it should) then they can add NT7.0 (and all the problems that will most likely come with it) to Windows 10, which will most likely be hated anyway.

        • Michaël

          That would be… not really cool. I also hope they will an NT 7.0 soon ;) And give it to the manufacturers early enough to make great drivers.

    • John

      NT 7.0 is saved for windows 9.

  • netsendjoe

    I can’t help but wonder if they are going to reset the build numbers when they make NT 7.0 or if they will go above 9999 for build numbers, because I was under the impression that some older apps that use version information might have problems reading a build number higher than that. It was the reason they decided to keep the kernel at 6.x … Windows should go SVN or GIT, imagine that.

    • yannick

      They will go over the 9999. A build number can’t go down. It’s the revision number for that Windows version and no matter what, it always has to go up, doesn’t matter if it is 6.4 or 7.0. We are able to predict the minimum build number for the next major iteration of Windows always, as it’s Always at least 400 higher than the current generation. So the RTM of Windows Threshold is at least version 6.4.10000.

      • Zac Bowden

        Is that true? I’m not sure if that’s a written rule, only that the build number must be divisible by 16. Take a read:

        • yannick

          It has been mentioned on the Windows blog somewhere that they will Always go up 400 builds at least, not sure if that is a “rule”, they just stated that that’s what will happen most of the time.

          • Zac Bowden

            Well, from Vista up to Windows 8, the build number always increased by 1600. This was broken with 8.1, which increased the build by only 400. So anything could go from here on out, but if we re-apply the 1600 rule, Windows 9 could see an RTM build number of 11200.

          • yannick

            The Windows team already mentioned that the 1600 builds up is a coincidense and not a rule.

          • John

            Windows 8 only was 900 builds, but then Microsoft skipped to 9200. Windows 8.1 was somewhere in the 9400s, and they skipped to 9600. Windows threshold should be 9.4.10000.

  • BreVDD

    Maybe they will make Windows more power efficient :)
    PS Microsoft if you read this, give us a preview soon :D.

    • Zac Bowden

      Even an unstable build leak would suffice :P *hint hint*

      • BreVDD

        Anything is fine :D

  • StarEy3

    Kernel updates usually means better support for newer hardware, but sometimes they also screw up older hardware, I can’t wait, just think about the possibility that it can boot even faster than Windows 8

  • Aaditya Menon

    A great news . Finally we know tat Win 9 is in progress……………….

  • Magnus

    I still do not like the idea of ​​a windows 9 I prefer a Windows 8.5 or somthing

    • Batıkan Doğan

      Perhaps it should have been Windows 8.2 Because both it will be Windows NT 6.4 and the most important innovation of it is a new traditional start menu.

  • Mike Greenway

    Without any leakers at all we know Microsoft has a division of people working on windows next every day (they always do), add to that the fact that the kernel has traditionally been advanced with new versions of windows and I think we can say there is a good chance of this particular leak be 100% true. A rare event!

  • Zetrosoft

    Good to see that it is not NT 7

  • Zetrosoft

    Windows X will be a bang ..

    • Alejandro Machado R.

      Hope it’s called X.

  • Joshua

    Can’t wait for Windows Treshold or btw Windows 9 to see the light soon :)

  • Mateer L

    is it me or do they suck at numbering their products? we’re stuck at 6.x forever!

  • James

    Are we still using Windows NT? How about coming up with a new operating system from scratch?

    • Dominic Maas

      That would never work, we would lose all driver support, and stability. And it would take years to rebuild the Kernel.
