Fix Windows Services will not start
Windows Services are applications that typically start when the computer is booted and run quietly in the background until it is shut down. Strictly speaking, a service is any Windows application that is implemented with the services API. However, services normally handle low-level tasks that require little or no user interaction. Here are some suggestions. But before you start, create a System Restore point manually.
Fix Windows Service start error
1] Check Services Startup type
To manage Windows Services, you have to open the Run box, type services.msc and hit Enter to open the Services Manager. Here you can set its startup type to Automatic, Delayed, Manual or Disabled. Check if the specific service with whom you are facing problems is not set to Disabled. See if you can start it manually by clicking on the Start button.
2] Troubleshoot in Clean Boot State
Boot in Safe Mode and see if the Service is starting. Many times, non-Microsoft services or Drivers can interfere with the proper functioning of System Services. Alternatively, you could also execute a Clean Boot and check.
3] Run SFC and DISM
Run the System File Checker ie. Run sfc /scannow from an elevated command prompt. Reboot on completion and check. Windows 10/8.1 users may repair their Windows System Image and see if it helps.
