[SOLVED] Windows Server 2016 Cumulative Updates Always Fail

[KaleBuddy]

I've been running into issues with cumulative updates failing on my windows 2016 remote desktop server farm. So far the 2019-02, 2019-03, and now the 2019-04 KB4493470 CU are failing to apply from my WSUS server and from catalog.microsoft.com offline bundle.


I've already tied the following to save you time...
Any suggestions are welcome and I've attached the CBS logs if I should include anything else please let me know.


net stop wuauserv
Ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
net start wuauserv

DISM.exe /Online /Cleanup-Image /RestoreHealth
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:F:\sources\install.wim:1/LimitAccess
sfc /scannow


net stop wuauserv
net stop bits
Remove-Item –path c:\windows\SoftwareDistribution –recurse
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v AccountDomainSid /f

[Sysnative Windows Update]

Hello!

The updates are failing due to the App Readiness service being disabled. Please re-enable the service via services.msc and everything should work again.

That completely resolved the issue. Thank you for your quick response!
