About Snow Update Service

Snow Update Service (SUS) is a Windows service that enables automatic or manual updating of Snow products.

SUS can be used for installing updates for:

  • Snow Inventory

  • Snow License Manager

  • Snow Management and Configuration Center

  • Software Recognition Service

  • Automation Platform

The SUS service can run without any user interaction in the background, installing updates. The SUS graphical user interface can be used to configure settings.

SUS is automatically installed during the installation of Snow License Manager and Snow Inventory. The default installation path is C:\Program Files\Snow Software\Snow Update Service.

The service regularly looks for product updates at the central Snow Update Server, and downloads and installs update files. SUS also automatically downloads new or updated application recognition rules from the Software Recognition Service (SRS) database. If automatic uploading of SRS data is enabled, which is the default, the SRS update cycle also uploads unrecognized data to Snow for analysis.

SUS uses a Content Delivery Network (CDN) to download updates. If the CDN is not available at the time of download, the update files will be downloaded via the central Snow Update Server instead.

Web services

SUS uses the following web services in online mode:


    The web service is used to get and post information about software updates.


    The web service is mainly used for downloading updates.

The functionality of the first web service ( will gradually be transferred to the second (, which will eventually replace the first one entirely.
