Updates failing TiWorker Server 2016

Hi, we have several servers that are failing to patch due to a Faulting Application.

Faulting application path: C:\Windows\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.14393.4222_none_7f13461e21e4fea5\TiWorker.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll

Do we know how to fix this error? All Servers 2016 and all the same error application

Thanks
Ryan

Hi Ryan,
Reset Windows update component

Then check for update again.

Try to in-place upgrade current system by a clean server 2016 ISO file, this way can fix system components and files issue

@RyanBrinch-5766 ...In 2016 please check if on your machine you have kb4601392 . Because with 2016 https://support.microsoft.com/en-us/topic/february-9-2021-kb4601318-os-build-14393-4225-c5e3de6c-e3e6-ffb5-6197-48b9ce16446e Their is a know issue documented where the update gets stuck at 24% . And during this time you will see Tiworker.exe crash . And is recorded in Application event logs . The fix is to get recent SSU installed through DISM and you should be good to go. This was a similar issue that i faced .

First check the above and if already have the latest SSU https://support.microsoft.com/en-us/topic/kb5001078-servicing-stack-update-for-windows-10-version-1607-february-12-2021-3e19bfd1-7711-48a8-978b-ce3620ec6362 Then disable 3rd party services or remove 3rd party components from the variables and then see if you still see the crash in tiworker.exe .

You can also collect a procdump for the process itself during the crash
