Environment
- App Control Agent: All Supported Versions
- Microsoft Windows: All Supported Versions

Symptoms
- High Disk Utilization at boot
- Slower than average log in times
Cause
The VDI device is reporting large numbers of changes in the USN Journal which causes the Agent to conduct a cache check, to find all the changes made.
Resolution
- Verify that the VDI Golden Image is in its own Policy.
- Navigate to https://ServerAddress/agent_config.php
- Click Show Filters > Value > contains > usn_journal_flags > Apply
- Either modify the existing Agent Config for the VDI Policy, or click Add Agent Config and use the following:
- Name: Disable CC3 on USN Journal Reported Changes
- Host ID: 0
- Platform: Windows
- Value:
usn_journal_flags=0
- Policy: Select the relevant VDI Policy (or Policies)
- Status: Enabled
- Save the Agent Config and verify the changes are applied to the Golden Image (and Clones) accordingly.
