1. Cryptographic Verification (Immediate Action)
Do not arbitrarily click "Allow" or "Block." Extract the SHA-256 hash of that specific MicrosoftEdgeUpdate.exe and verify its digital signature chain immediately. If the signature is invalid, revoked, or missing, you must treat the endpoint as actively compromised.

2. Dissect the IFEO Payload (Immediate Analysis)
Determine exactly what value is being written to HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\MicrosoftEdgeUpdate.exe. If the executable is attempting to set a "Debugger" string value pointing to an unauthorized path, you are actively witnessing a process interception attempt.
