Beginning with Release 270 drivers for desktops, when NVIDIA Update or GeForce Experience is installed, the software creates the UpdatusUser account. This account runs the NVIDIA Update service for updating drivers and application profiles through the NVIDIA server. The service cannot be run without this account.
NVIDIA has taken every precaution to make the driver implementation of UpdatusUser as secure as possible. This implementation has been audited by Veracode (www.veracode.com), a third party security auditor, and has been given a rating of "Best". NVIDIA Update and GeForce Experience, with the UpdatusUser account, is considered a low security risk implementation.
