InstallHinfSection API does not remove driver related registry keys during driver uninstallation

I am trying to use InstallHinfSection API for the kernel driver's installation/uninstallation on Win10. I encounter no issues when using it to install the driver. It successfully copies the driver to the DriverStore and creates the necessary RegKeys and Service. However, it does not work as intended during uninstallation. Although the driver is removed from the DriverStore, the RegKeys and Service are not removed from the registry. After uninstallation, "sc query mydriver" shows driver in STOPPED state which is not correct.

Am I missing something in the call to InstallHinfSection or in the INF file?

Below driver traces remain in the registry:

Computer\HKEY_LOCALMACHINE\SYSTEM\ControlSet001\Services\mydriver
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mydriver

Command for installation:

RUNDLL32.EXE SETUPAPI.DLL,InstallHinfSection DefaultInstall 132 C:\mydriver.inf

Command for uninstallation:

RUNDLL32.EXE SETUPAPI.DLL,InstallHinfSection DefaultUninstall 128 C:\mydriver.inf

Below is the INF file I am using:
