Battle.net Desktop Client
Battle.net.exe is the core executable for Blizzard's Battle.net Desktop Client. It coordinates sign-in, patch delivery, game library synchronization, launcher updates, and the in-app overlay. The process runs in the background to ensure games launch with current data and settings while communicating with Blizzard servers.
It initializes the launcher UI, maintains a persistent session, loads game modules, and handles patch checks and asset caching. It uses TLS-secured connections to Blizzard servers to fetch updates and manage entitlement checks for installed games.
Reasons it's running:
Battle.net.exe is Blizzard's official launcher core. It is digitally signed by Blizzard Entertainment, Inc., located under the Battle.net folder, and required to run the Battle.net Desktop Client.
Yes, when installed from Blizzard's official site and located at C:\Program Files (x86)\Battle.net\Battle.net.exe with a Blizzard-signed certificate.
The launcher performs updates, patch checks, and asset loading in the background; if it stays high for long, consider updating or restarting the launcher and checking for faulty cache.
To disable, turn off 'Start Battle.net with Windows' in settings or disable the startup entry in Task Manager. To uninstall, go to Windows Settings > Apps > Battle.net and choose Uninstall.
Logs are usually in %LOCALAPPDATA%\Battle.net or %PROGRAMDATA%\Battle.net; check these locations for error messages and troubleshooting details.
