KB4601318 fails to update, fails at 24% Windows Server 2016

Kevin S 96

Hello,

I have 3 virtual servers that have this exact same issue where when I try to update KB4601318, it stalls at 24%. The servers are 2016 servers, I have disabled anti-virus, I have rebooted, followed instructions on this blog, added RAM and enabled and disabled firewall. I have updated 15 other servers in my environment successfully, running the same antivirus software, same kind of setup. The servers all have 2 or 4 processors, 8 GB or 16 GB of RAM and at least 200+ GB of available disk space. No errors in the event viewer that I can see.

I've let the update run on these machines for 2 hours and what happens is that it will install KB890830 and KB4601392 on all of these machines but not KB4601318 on any of them. It gets stuck at 24% and then eventually stops and reads "KB4601318 is available" "Updates are ready" and Download button is enabled. If I click it, it goes through the exact same cycle where it stalls at 24% again.

Any assistance would be appreciated.

Same situation here, setting up brand new AD environment, ESXi... Both DC and term server both stuck at 24% since yesterday... New servers, no past issues, confused on this as well.

Both an older 2016 Hyper-V VM and brand new 2016 Hyper-V VM unable to complete updates! Hope this is fixed soon. I doubt a server with no updates will last for long!

So if we've already downloaded and installed the SSU we will need to install the CU using the workaround? Or should we wait until a fix is available?

I've successfully ran the KB on 2 machines at this point. Pretty much the steps other people listed. I can do on a few VMs but dozens or hundreds across an organization would not work for this....too resource intensive for 1 admin!

-Download the update from Microsoft Catalog (.msu file)

-Stop Windows Update Service. For me it didn't stop so I had to set the service to Disabled then go to a command prompt and run "sc queryex wuauserv" then do a "taskkill /f /PID xxxx" (where xxxx is the PID listed from the prior query command).

Delete or rename the C:\Windows\SoftwareDistribution\ folder

Now run the .msu update file. A few times I got a pop-up about a stub file error. What is that? Anyway, I waited a minute and ran the .msu again and it unpacked and ran successfully.

Set Windows Update back to manual

Reboot. KB installed.

Same here. All Azure 2016 VM's stuck at 24%.
Update: I installed one VM following the procedure above and this worked, but this seems a global issue which microsoft should fix. I have many machines with the same issue

Same.....numerous Azure 2016 servers stuck at 24% with that specific KB. No other issues with other KBs. Microsoft needs to address this.

Yeah, we can't hack our way through manually updating every single machine with the failure. This is absolutely an issue Microsoft needs to fix ASAP.

Hey there - a short Update!
I managed to fix it for myself!
I really don't know what step fixed it so im just giving your the workflow i did .

I shut down "bits" and "wuauserv" with the net stop command.

I deleted all possible files from C:\Windows\SoftwareDistribution

I tryed it again with Windows Update - a few times while reebooting after every 30 mins into process after there was no new entry to the cbs log.

After one of those shutdowns i downloaded the Update from Microsoft Catalog what @Anonymous already posted above.

I restarted the Server again and the first thing i did after the reboot was opening the cmd and task manager to see what PID the wuauserv became.

In the opened cmd i typed taskkill /f /pid [YOUR_PID] and executed the downloaded update manually. After that the Update ran to the 100% in the manual installation.

After the next reboot it worked.

I hope i could help u!
