Windows Event ID 7036 — Service State Changed
Logged when a service enters a running or stopped state.
Why It Matters
Tracking state changes for security-critical services (Windows Defender, Windows Firewall, Event Log) can reveal tampering. A security service stopping without a corresponding start shortly after is a red flag.
Key Fields
Investigation Tips
- 1.Monitor for Windows Defender (WinDefend) or Firewall (MpsSvc) stopping without a corresponding start.
