What is nuance-update.exe?
nuance-update.exe is the Nuance updater executable that handles checking for, downloading, and applying updates to Nuance Dragon and related software.

nuance-update.exe communicates with Nuance update servers to verify available patches, downloads installer packages, verifies digital signatures, and launches the installer to apply updates. It may spawn background tasks and run at startup or when the main Nuance app requests updates.
