The file is signed by Microsoft, and the process is part of normal user activity. Historical data shows similar events being marked as false positives, indicating this is likely a benign activity.\n\n**IOC Analysis:** The FILE_PATH is located in C:\\Program Files (x86)\\Microsoft\\Edge, which is a known legitimate software directory.
