There is no requirement to stop any service but it is advisable to disable at least search as the installation of the binaries will take long time and that is way to avoid it.
You wrote that you are applying the update using PSConfig.exe. Maybe you just made a mental shortcut so sorry to point that out. You first need to install updates using binaries in case of SP2016 you need to install 2 main update and language dependent (even if you use just English you still need to do it) only after you install binaries you apply them using psconfig.
with regards to the language dependant fix:
"The product group released the February 2019 Cumulative Update for
SharePoint Server 2016 product family. Be aware that only a language
independent fix was released with February 2019 CU. The latest
language dependent fix was released with October 2018 CU."
this is quote from the link below
- You can install latest CU as they are cumulative there is no need to install in between CUs (usually there are couple of exceptions)
Please note that the latest CU for SP2016 has some issues and MS advises not to install it.
Have look here (Stefan has as well some first rate advise about the update process have read through the links on the bottom of the post)
I modeled my update process after Sharepoint DSC (Desired State Configuration) and I disable those services:
Using this script:
Write-Host "Stopping services"
Set-Service -Name "IISADMIN" -StartupType Disabled
Set-Service -Name "SPTimerV4" -StartupType Disabled
$iisreset = Start-Process -FilePath "iisreset.exe" `
-ArgumentList "-stop -noforce" `
$timerSvc = Get-Service -Name "SPTimerV4"
if($timerSvc.Status -eq "Running")
$ErrorMessage = $_.Exception.Message
$FailedItem = $_.Exception.ItemName
Write-host "Something went wrong durin Step 2: stopping of the services"
