How to Delete Windows Service?

Author: HP Fuchs | Category: Windows

On my Windows 2003 test server I install and remove a lot of Oracle and SQL Server software. I create and drop databases a lot. Usually I work in a rush on that server, so removing instances and software isn’t always so clean. Sometimes a windows services sticks and cannot be removed. It has to be cleaned up manually. The easiest way to remove windows services is deleting their entries in the registry. All windows services are listed under

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services

Once you delete an entry its service is removed and will not show up in the services panel anymore after a system reboot.

    Thank you for your tip regarding removing services in the Services panel. I too install Oracle many times on the same machine got a build up list of Oracle services on the panel. Now, I was able to remove all the unwanted ones.

    That is definitely not the recommended way. To delete a service use the command line tool sc. For instance

    sc delete OracleServiceORCL

    Hallo Stefan

    You are right. I learned about the sc (service control) windows shell command only recently at my new job. Thanks for pointing out.
