  • Entry
  • Associated product(s)
This application example describes how to configure the Microsoft Windows Server Update Service (WSUS) and set up the Windows Clients for receiving Windows updates via the WSUS.

The documentation describes the concept of Windows as a Service and illustrates the different options for receiving Windows updates and the associated restrictions respectively hazards for WinCC Runtime stations.

Further, the documentation explains different variants respectively servicing channels of Windows 10 and outlines why Windows10 LTSB in combination with the visualization software from Siemens entails significantly less dangers than the other servicing channels.

Benefits provided when using a WSUS:

  • The planned installation of Microsoft updates
  • No unplanned restarts with resulting loss of data
  • No unforeseen incompatibilities (e.g. with feature updates)

Finally, a possible scenario for the provision of updates via a WSUS for Windows 10 LTSB Clients might look as follows:
