The registry entry shown in the screenshot is a broken COM/CLSID registration.
It points tonotification_helper.exeunder the TeamSpeak install path, but the executable no longer exists.
This leaves an orphanedLocalServer32entry underHKEY_CLASSES_ROOT\CLSID, likely from an incomplete uninstall or update.
Please consider cleaning or correcting this during uninstall/update to avoid orphaned registry entries.
