  Telemetry is the automated sensing and collection of data from a remote
device. It is often used to provide better services for users. Microsoft uses
telemetry to periodically collect information about Windows systems and to help
improve user experience and fix potential issues. Windows telemetry service
functions by creating RBS files on the local system to reliably transfer and
manage the telemetry data, and these files can provide useful information in a
digital forensic investigation. Combined with the information derived from
traditional Windows forensics, investigators can have greater confidence in the
evidence derived from various artifacts. It is possible to acquire information
that can be confirmed only for live systems, such as the computer hardware
serial number, the connection records for external storage devices, and traces
of executed processes. This information is included in the RBS files that are
created for use in Windows telemetry. In this paper, we introduced how to
acquire RBS files telemetry and analyzed the data structure of these RBS files,
which are able to determine the types of information that Windows OS have been
collected. We also discussed the reliability and the novelty by comparing the
conventional artifacts with the RBS files, which could be useful in digital
forensic investigation.
