Update Ollama on Windows

  • 1

    Quit Ollama from the system tray

    Right-click the Ollama icon in the system tray → Quit Ollama. The installer cannot replace files that are in use by a running service.

  • 2

    Download the latest OllamaSetup.exe

    Get the new installer from the download page or directly from ollama.com/download/windows.

  • 3

    Run the installer over the existing install

    Double-click the new OllamaSetup.exe and follow the wizard. It installs to the same location as the previous version. Your downloaded models, settings and history are preserved.

  • 4

    Verify the new version

    cmd.exe — new window
    C:\> ollama --version
    ollama version 0.6.5
    Open a new terminal after updating. Old terminal windows may still show the cached version string.

Update your models after upgrading Ollama

Updating Ollama does not automatically update your downloaded models. To get the latest version of a model:

cmd.exe
# Re-pull the model to get the latest version:
C:\> ollama pull llama3
pulling manifest...
success
# Check which models you have:
C:\> ollama list
NAME ID SIZE MODIFIED
llama3:latest a6990ed6be10 4.7 GB Just now

You only need to re-pull a model if a new version was released. Model versions are tied to their tag (e.g. llama3:latest) — re-pulling latest always gets the newest available weights.

Update questions

Will updating Ollama delete my models?
No. Running the new installer over the existing one updates only the Ollama binary. Your downloaded models in the .ollama/models folder are untouched.
How do I know when a new version is available?
Ollama does not send update notifications on Windows. Check github.com/ollama/ollama/releases for new releases, or follow the Ollama GitHub repository for notifications.
Can I update Ollama with winget?
Yes: winget upgrade Ollama.Ollama. If winget does not find an update, the package may not be updated in the repository yet — in that case download manually from ollama.com.
After updating, Ollama is slower or behaves differently
New versions sometimes change default parameters or quantization handling. Try re-pulling your model: ollama pull modelname. If issues persist, check the release notes for breaking changes.
