# Windows Defender Application Control operational guide
**Applies to**
- Windows 10
- Windows Server 2016 and above
After designing and deploying your Windows Defender Application Control (WDAC) policies, this guide covers understanding the effects your policies are having and troubleshooting when they are not behaving as expected. It contains information on where to find events and what they mean, and also querying these events with Microsoft Defender for Endpoint Advanced Hunting feature.
## WDAC Events Overview
WDAC generates and logs events when a policy is loaded as well as when a binary attempts to execute and is blocked. These events include information that identifies the policy and gives more details about the block. Generally, WDAC does not generate events when a binary is allowed; however, there is the option to enable events when Managed Installer and/or the Intelligent Security Graph (ISG) is configured.
WDAC events are generated under two locations:
- Applications and Services logs Microsoft Windows CodeIntegrity Operational
- Applications and Services logs Microsoft Windows AppLocker MSI and Script
