A new Windows ‘Threshold’ build number has been discovered and it proves that the next version of Windows will get a kernel version of 6.4.
Build 6.4.9788.0 appeared in twitter user @Stealth2013’s Windows Store logs. The Windows Store logs show developers what OS people use to download their apps, other Windows Threshold builds have appeared in these logs before, but this is the first known build to have an NT version of 6.4 (Windows 8 was 6.2, 8.1 was 6.3)
The fact that Threshold will get an updated kernel most likely means that it won’t be delivered through Windows Update, it might be another Store upgrade like 8.1.
