Symptom

Windows Security warns that DU Meter is trying to make unauthorized changes to memory or controlled folders.

Cause

If DU Meter is configured to save periodic reports to a Windows-protected folder (such as Desktop or Documents), the Controlled Folder Access feature may block the operation.

Solution

Step 1: Check Report Save Location

Ensure periodic reports are not being saved to folders protected by Controlled Folder Access. You can change the report save location in DU Meter's settings.

Step 2: Check Windows Security Logs

1. Open Windows Security from the Start Menu
2. Go to Virus & threat protection
3. Select Ransomware protection
4. Check the logs/events to see exactly what was blocked

Step 3: Add DU Meter as an Exception (if needed)

If you want DU Meter to save reports to a protected folder, you can add it to the allowed apps list in Controlled Folder Access settings.

Note: The DU Meter Service itself does not require special folder write access. Warnings are typically related to the report file saving feature.
