| Issue | Symptom | Windows 11 Fix |
| :--- | :--- | :--- |
| COM Port Jitter | Connection keeps dropping mid-diagnosis. | Go to Device Manager > Ports > Autocom COMxx > Properties > Port Settings > Advanced. Change COM Port Number to COM 3 or COM 5 (avoid COM 1/2/4/9). |
| USB Power Surge | Popup: "USB device malfunctioned." | The Autocom draws current. In Windows 11 Power Options > Advanced > USB Settings > Disable USB selective suspend. |
| Black Screen on Launch | Software opens but shows only a black GUI. | This is a DirectDraw issue. Create a shortcut to Delphi Autocom. In Target, add /opengl at the end. Example: "C:\Delphi\Autocom.exe" /opengl |
| VCI Not Found | Software says "No interface connected." | Run Delphi VCI Manager (if installed) as Admin. Click "Restore Firmware." Wait 60 seconds. Unplug/replug USB. |
| Slow CAN Bus | Vehicle reads data, but takes 10 seconds per request. | Windows 11 background scanning. Disable IPv6 on your Wi-Fi/Ethernet adapter. Disable Windows Defender Network Protection temporarily. | Performance comparison:

Verdict: If your Windows 10 machine works, do not upgrade. If you have a new laptop with an Intel 12th/13th/14th Gen CPU that requires Windows 11 (due to thread director), then Windows 11 is acceptable with the tweaks above.
