windows service update exe options without remove / reinstall

I've a windows service installed and working fine with a path to exe :

c:\myproject\mybinary.exe -home d:\home - generateFiles false

I want to add another option :
-option optionValue

Since I have around 200 different services, installed in a 15 different servers, it is complicated to uninstall and reinstall with the new option.

Is there somehow to add the new option without any change to the service binary?



Get-WmiObject win32_service -filter "Name='My Service'" `
    | Invoke-WmiMethod -Name Change `
    -ArgumentList @($null,$null,$null,$null,$null, `
    "c:\myproject\mybinary.exe -home d:\home -generateFiles false -option optionValue")


Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Services\My Service" `
    -Name ImagePath -Value "c:\myproject\mybinary.exe -home d:\home -generateFiles false -option optionValue"

You would need to restart service afterwards: Restart-Service "My Service". See also here.
