Typically, the SEST file extension indicates that a file is a Software Update Services Export Store file. These types of files can be found on a system that utilizes Microsoft's Software Update Services (SUS), a program utilized primarily by system administrators to manage the distribution of updates released through Windows Update towards systems in a corporate environment. More information about SUS and its associated formats can be found at Microsoft's official SUS documentation.

Opening and Using SEST Files - Software Update Services

When it comes to handling SEST files related to Software Update Services, you'll need a system with SUS to do so. A SEST file stores the details of the different updates available, and SUS uses it to ensure all corporate systems receive necessary updates. To use a SEST file with Software Update Services, one would place the file in the proper directory, and SUS would use the file to update its database of available updates. Further instructions can be found on Microsoft's guide on managing settings for software updates.
