Before any upgrade it is recommended to make a backup. To do this, we have to stop the SDP server. Yes, I can stop the ManageEngine ServiceDesk Plus Service under Services, but in the Admin Guide, you can read:

Shutdown ServiceDesk Plus on Windows

1. Click Start -> Programs -> ManageEngine ServiceDesk Plus -> Shutdown ServiceDesk. A confirmation message is displayed.

2. Click OK to proceed with the shutdown.

Alternatively, right-click on the system tray icon and select Shut down Server. A confirmation message is displayed. Click OK to shut down ServiceDesk Plus. 

I am using Windows Server 2012 R2 (German), SDP v9301

There is no Start - Programs - Managengine etc and there is no icon in the system tray, where I could right-click. Are there missed components, which were not have been installed during the initial installation? Ho do I get this to work on my server?
