How to remove an existing MongoDB service when the Win7 platform installs MongoDB

1. Open "Run" (win+r), enter "Services.exe" to confirm the existence of MongoDB service


2. Run cmd, use SC command to manage Windows service (if you cannot delete successfully, run cmd as an administrator)


3. If the MongoDB service is running, please stop the service first: SC stop MongoDB
4. Delete MongoDB Service: SC Delete MongoDB.
You can remove the MongoDB service (if the service is also displayed when the list of services is refreshed, try closing the currently open service window to reopen the view).
