Windows support is implemented and functional. We welcome feedback on any issues!
Prerequisites
- Windows 10/11 (64-bit)
- OISP installed (see Installation)
- CA certificate installed
- Administrator privileges
Start Capturing
-
Launch OISP from the Start Menu or system tray
-
Install CA (first time) — Right-click tray icon → “Install CA Certificate”
-
Start Capture — Right-click tray icon → “Start Capture”
- Accept the UAC prompt (WinDivert needs elevation)
-
Open Web UI — Go to http://localhost:7777
Generate AI Activity
Make an AI API call to test:
Python
import openai
client = openai.OpenAI()
response = client.chat.completions.create(
model="gpt-4o-mini",
messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)
PowerShell
$headers = @{
"Content-Type" = "application/json"
"Authorization" = "Bearer $env:OPENAI_API_KEY"
}
$body = @{
model = "gpt-4o-mini"
messages = @(@{role = "user"; content = "Hello!"})
} | ConvertTo-Json
Invoke-RestMethod -Uri "https://api.openai.com/v1/chat/completions" -Method Post -Headers $headers -Body $body
See Events
The Web UI at http://localhost:7777 shows:
- ai.request — Outgoing API calls
- ai.response — Responses with tokens and latency
- Process info — Which app made each call
Tray Icon Controls
Right-click the OISP icon in the system tray:
| Action | Description |
|---|
| Start Capture | Begin intercepting AI traffic |
| Stop Capture | Pause capture |
| Install CA Certificate | Add CA to Windows trust store |
| Settings | Configure exports, filters |
| Exit | Quit OISP |
Tray Icon Colors
| Color | Status |
|---|
| Green | Capturing |
| Yellow | Running but not capturing |
| Red | Error |
Troubleshooting
No events appearing?
- Check tray icon is green — Capture must be started
- Check CA is installed — certmgr.msc → Trusted Root CAs
- Check WinDivert — Run
sc query WinDivert in Admin PowerShell
UAC prompt every time?
This is normal. WinDivert requires elevation. You can configure auto-start to reduce prompts.
Antivirus blocking?
Add OISP folder to antivirus exclusions. WinDivert drivers may be flagged.
