If the May 2019 Update (1903) and November 2019 Update (1909) share the same servicing content and CUs, and 1903 is already considered “Ready for Business,” will it be safe to consider 1909 as “Ready for Business” by Microsoft’s standards?

The version you see with the “winver” command is the version you are running.

Currently the bug with the cumulative updates showing twice is due to this:  the cumulative updates are silently packaged with the Servicing Stack Updates.  They’re supposed to install at the same time, but in certain circumstances, such as the system being too far behind on CU updates and missing certain Servicing Stack prerequisites, they do not.  The servicing stack update will report that it’s installed as the CU, and then during the actual CU update, the same update will show as having installed twice, with a (2) listed in the Windows Update History.

To verify what actually made it into the system, go to the “C:\Windows\servicing\Sessions” directory, and read the numbered XML docs that have today’s timestamp.  Near the top will be a line similar to the following:

<Phase seq=”1″>
<package id=”Package_for_KB4521863~31bf3856ad364e35~amd64~~18362.411.1.3″ name=”KB4521863″ targetState=”Installed” options=”17″/>
</Phase>

That tells you what actually installed.  My guess is that in one of those files, you’ll see the KB4521863 number I just pasted, because that’s the servicing stack update from today.  Were you to reboot and check again, you’d indeed see KB4517389 available to install (“again”) and that is what you want to hold off on doing.

Hi Anonymous,

Good call. The KB4521863 SSU from October 8th was indeed installed. I opened the XML files, did a “Ctrl+F” search for keyword “Installed” and found the following packages installed:

Package~31bf3856ad364e35~amd64~~10.0.18362.1″ name=”Windows Foundation” targetState=”Installed”

<package id=”Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~10.0.18362.1″ name=”Windows Foundation” targetState=”Installed” options=”5″/>

<package id=”Package_for_KB4521863~31bf3856ad364e35~amd64~~18362.411.1.3″ name=”KB4521863″ targetState=”Installed” options=”17″/>

<package id=”Package_for_KB4516115~31bf3856ad364e35~amd64~~10.0.1.0″ name=”KB4516115″ targetState=”Installed” options=”0″/>

<package id=”Package_for_DotNetRollup~31bf3856ad364e35~amd64~~10.0.1.3012″ name=”KB4515871″ targetState=”Installed” options=”0″/>

<package id=”Package_for_RollupFix~31bf3856ad364e35~amd64~~18362.418.1.9″ name=”KB4517389″ targetState=”Installed” options=”17″/>

This may sound silly, but try checking for updates again. There have been incidents where the CU (supposedly) installs twice at least as recorded in the History, but maybe just didn’t finish the first time. If it shows up again, install it again.

(It’s happened to me)

Thanks PKCano. I checked for updates a second time and KB4517389 began installing again. Now to roll back to September 10th – OS Build 18362.387 (KB4517211).

Help. I cannot uninstall KB4517389 because it does not appear in my “Installed Updates” list after a reboot.

I just opened the box on a Dell Optiplex 7060 Micro, configured Windows 10 1903 (OS Build 18362.175 – June 11, 2019) and clicked “Check for Updates” (I wanted to install OS build 18362.388 – October 3, 2019). Windows Update just installed the following:

• 2019-10 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4517389)
• 2019-09 Security Update for Adobe Flash Player for Windows 10 Version 1903 for x64-based Systems (KB4516115)
• 2019-10 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903 for x64 (KB4524100)

I have been reading Susan Bradley’s Master Patch List, where she recommends to “Never install an update to a newer version of .NET.” The latest patch list says OS build 18362.388 – October 3, 2019 is safe to install, but Woody says to “Defer” on today’s KB4517389. How can I uninstall it if it does not appear in my “Installed Updates” list? Windows also reports that I am still running OS Build 18362.175 – June 11, 2019. Please advise, thanks.

Thank you PKCano, that is very useful information.

As far as latest patches are listed, I am seeing Dynamic Updates and Previews for October in our WSUS server catalog (2018-09). I am going to hold off on these for now.

Regarding latest CUs, I am only seeing 9/17/18 patches listed in our WSUS server catalog, not 9/20/18 ones, so I guess this is a good thing. I am also seeing Intel microcode updates, but I will hold off on those as well for now.
