Have you come across a situation where uninstalling a software leaves its Service or driver entries in the registry, and Windows tries to load them at every boot, fails and logs the error to the System Event log at every startup? Here is how to delete a service which is leftover in Windows. Instructions apply to Windows XP through Windows 10.
When a driver or service entry is leftover in the registry but the corresponding files are missing, the Event Log would record an entry with
ID:7000 at every start.
Source: Service Control Manager
Event ID: 7000
The DgiVecp service failed to start due to the following error:
The system cannot find the file specified.
This post tells you how to remove an orphaned service using the registry, SC command-line or using Autoruns. Before proceeding further, create a System Restore point and/or a complete Registry backup.

When you remove a service, others that depend upon the service would fail to start, returning error "System error 1075 has occurred. The dependency service does not exist or has been marked for deletion.". So, it’s advisable to first check if there are any dependents.
You can check that in Services MMC by double-clicking on the item you’re going to delete and clicking the Dependencies tab. The list of components that depend on that service are shown below. Here is an example, where “Fax” depends on “Print Spooler” to start.
While most third-party services don’t have any dependents, some do. It’s always advisable to take a look at this tab before clearing the item.
Another way to verify the dependents is to run this command from a Command Prompt window. (example, Print Spooler)
sc enumdepend spooler
If you find that no dependents exist for a service, you can proceed to deleting the leftover item using one of the following methods. Method #1 is probably the easiest of all the three methods.
Autoruns is a must-have tool which helps you manage Windows startup, services, drivers, Winsock providers, Internet Explorer add-ons, Shell extensions and much more.
Download Autoruns and run it. From the Options tab, tick Hide Microsoft Entries, so that only the third-party entries are listed. Press F5 to refresh the listing. Click the Services tab, from where you can remove unwanted or leftover items.
sc delete serviceshortnamename
Where serviceshortname refers the short name of the service, instead of its display name. To find the short name, open Services MMC and double-click a service.
Example 1: Short name for Automatic Updates is wuauserv, and display name is Automatic Updates.
Example 2: Google Update Service (gupdate) is the display name, and gupdate is the shortname
Another way to find the short-name of a service is using this command-line:
sc getkeyname "service display name"
which in this example is:
sc getkeyname "Google Update Service (gupdate)"
Once the service short name is obtained using any of the above methods, use this command to remove it:
sc delete gupdate
This removes the Google Update service.
To manually remove a service from the registry, use these steps:
Start Regedit.exe and navigate to the following branch:
Each sub-key under the above registry key represents a driver or a Service. The key name is also the short name of the service. Also, you should be able to identify the entry easily by looking at the DisplayName and ImagePath values in the right-pane in the Registry Editor.
Find the entry you want to delete, right-click the appropriate key, and choose Delete. Exit the Registry Editor.
