Windows 10: Trying to understand KB, version and build numbers and release dates

In August, my x86 Windows 10 Pro computer had Cumulative Update KB4512941 successfully installed three times, on 26, 28 and 29 August. According to the Windows Update history page, this update to build 18362.329 was first released on 30 August, so did I get three pre-release versions? This machine has never had Insider builds.


In the past couple of days, the machine has received a Feature Update to version 1909 followed by CU KB4515384. The FU took the machine from build 18362.329 to 18363.329, whereupon the CU took it to 18363.356.


I try to have a look at the KB article before applying each update. This hasn't always been possible in cases where the article has first appeared a week or two after the update has been released. Now when I looked at the article, it claims that the update is for v.1903 and brings the build up to 18362.356. There are no entries on the WU History page for v.1909 even though it was released generally some time ago.


According to my Installed Updates listing, v.1909 was installed by 'Enablement package' KB4517245. The support link gives a 404 Page not found error.


View Update History invites me to See what's new in this update; when I click on the link, I'm taken to a screen headed Welcome to the May 2019 Update, so not so much to learn there.


Can anyone help me unravel this tangled web, or at least guide me to documentation about what's going on?

• What are the differences between 18362.356 and 18363.356?
• Why is this x86 machine receiving updates before they're released when the x64 machine on the next desk isn't?
• Previous Feature Updates have removed both the Update history and all restore points, but not this time. Why not?
• CU KB4515384 did remove all restore points earlier than the one WU created. Why?
• Where can I find out what's new in this Feature Update?

Windows build number and correlation to KB number

Windows 10 Version 1609 had an intial build number of 16299.0 but 16299.15 was the actual first stable release build and the current revision of of build 16299 as of October 17 2017 is 16299.19. The KB that upgrades the initial 16299.15 build to 16299.19 is KB4043961. The only way to uninstall a Feature Update is to revert to your previous version of Windows. There isn't a KB associated with them. There is no KB associated with 16299.15 only the ISO that was released around October 2nd 2017

If you want to revert back to build 16176 or 16288 it would mean reverting back to a Insider Preview RS3 build of Windows 10. Insider Preview builds expire after a period of time. At this point you would have to reinstall Windows 10 to revert back to one of those builds since the amount of time between 16288.1 or 16176.1000 and 16299.15 is greater then 15 days.

You might be able to revert to the previous version of Windows provided it's been less then 15 days since you install 16299.15 and/or 16299.19

This method will not work.

There isn't one and the build numbers you want to use are Insider Preview builds of the Fall Creators Update so they also don't KB numbers associated with them.

• 10.0.16176.1000 was released back on April 14 2017
  
• 10.0.16288.1 was released back on September 12 2017
  
• All stable Windows 10 updates which change the build number can be found here
  

 

Windows build number and correlation to KB number

So the Fall Creators Update basically bricked my dev environment and I have lost several days of work due to it. Anyway, I need to roll back the updates but to a certain Windows build number. Really, I need at a minimum build 16176 and less than 16288. So I am trying to figure out the KB number so I know which updates to uninstall. Not sure if this would resolve the issue but worth a shot.

Just remembered too. The other option is I have a computer that doesn't have the Fall Creators Update and works fine. However it is below 16176. I could manually apply the updates to bring it to that build using:

Microsoft Update Catalog

But it only takes KB numbers. I don't know what KB = 16176.

This doesn't provide the KB numbers either:

Release Notes for Windows Subsystem for Linux

 

Latest Update KB Number Version 1511

Let me please explain better.

I have Win. 10 Version 1511, OS Build 10586.545 installed.

I have been made aware from another post on a different subject that various KB numbered upgrade releases have been made to this version.

I would like to know where I can establish these upgrades that have been applied.

I Have looked at the "Settings" menu but can't find.

Hope you can help.
