*Environment:*

• OS: Windows 11 (reproducible)
• Product: Zabbix Agent 2 (Windows)
• Zabbix Server reachable; active checks OK
• Same behavior observed with the version referenced in ZBX-24918

*Description:*
`DebugLevel` set in an included configuration file under `zabbix_agent2.d` is ignored on Windows. The same approach works correctly on Linux.

*Steps to Reproduce:*

1. Install Zabbix Agent 2 on Windows 11.
2. Create file:
`C:\Program Files\Zabbix Agent 2\zabbix_agent2.d\windows.conf`
3. Put the following content in the file:

   LogFileSize=0
   DebugLevel=5
   Server=X.X.X.X
   ServerActive=X.X.X.X
   Hostname=TEST
   

4. Restart the “Zabbix Agent 2” service.

*Actual Result:*

• Agent restarts and connects to the Zabbix server with the correct `Hostname` (confirming the include file is read).
• `DebugLevel=5` is not applied; the agent keeps default verbosity.

*Expected Result:*

• `DebugLevel=5` should be applied when defined in an included file on Windows, same as on Linux.

*Additional Verification:*

• On Linux, placing `DebugLevel=5` in `/etc/zabbix/zabbix_agent2.d/debian.conf` works correctly (include is read and debug level changes).
• Tried also with the version in ZBX-24918 → same effect (debug level ignored on Windows).
