How to uninstall a service completely from an application in the next upgrade which isn't a major upgrade - wix

Question

I am trying to uninstall an installed service that has several components but not able to.
Could anyone please help me with the uninstalling tags too? I did a lot of searches but couldn't run anything successfully.
Just putting ServiceControl tag and removing all the components work? I tried that but didn't work. How do you deal with components and dependencies? Need logic and syntax help.
Below is my code that installs the service in the previous version. Please let me know of the tags that I have to add to remove this.

Answer 1

MSI Minor Upgrades can't officially remove components or features. The workaround (Hack) is to keep the original components but supply them a zero byte file and set the Revaluate attribute (transitive bit in MSI) to true and give it a condition that will always evaluate to false. This way the Windows Installer transitions this component to not installed and the service is stopped and removed.
You'll have to keep this 0 byte fake component around until you do your next major upgrade. Then it can be removed.
To be honest, Minor Upgrades are very picky and if you don't already know these rules you might be better served by always doing major upgrades until you do. Minor upgrades can push you into a corner really hard if you let it.
