Delete oracle services

Question

How can I delete the following oracle services?
OraclePI1102TNSListener
OraclePI1102iSQL*Plus
I have uninstalled the SAP system and manually deleted the registry keys
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\OraclePI1102TNSListener and
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\ORACLEPI1102ISQL*PLUS
but these services still exist.
I tried deleting these from the registry directly but it returns "Error while deleting key" HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_ORACLEPI1102TNSLISTENER
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_ORACLEPI1102ISQL*PLUS
Thanks

Hello Cons,
Normally it should not be necessary to manually delete a service. Uninstalling an application should remove its associated service,are sure that you have unstalled all the compnents,just check in add or remove programs for any SQL component present and uninstall.
However, the process is:
Run Regedit or regedt32.
Find the registry entry:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
Find the service there and delete it.
You may wish to look at the keys and see what files the service was using and perhaps delete them also.
You will have to reboot before the list gets updated in server manager.
I some programs are cunning and prevent you from removing their service easily. These change the permissions to make it more difficult for you to delete them. For these you will have to right click on the u2018serviceu2019 in regedit (regedt32), go to permissions and grant the administrator full control before the service can be deleted.
Hope it helps
