The code to install a service:

@ECHO Installing Service...
@SET PATH=%PATH%;C:\Windows\Microsoft.NET\Framework\v4.0.30319\
@InstallUtil  C:\Unlock_4_Service\bin\Debug\Unlock_4_Service.exe
@ECHO Install Done.
@pause

@InstallUtil <.exe file path of your windows service>

Code to uninstall the service

@ECHO Installing Service...
@SET PATH=%PATH%;C:\Windows\Microsoft.NET\Framework\v4.0.30319\
@InstallUtil /u C:\Unlock_4_Service\bin\Debug\Unlock_4_Service.exe
@ECHO Uninstall Done.
@pause

@InstallUtil /u <.exe file path of your windows service >

Save the 2 files as service_install.bat and service_uninstall.bat

Run the files as administrator, every time you have to install or uninstall the service.
