# Import a Certificate in Patch My PC Publisher

*Applies to: Patch My PC Publisher V3.x*

The **Import Certificate** option in Patch My PC (PMPC) Publisher allows you to import a code-signing certificate using a PFX file that includes the certificate's private key, which Publisher uses to sign content it publishes.

To import a PFX certificate:

1. Load Publisher.
2. On the **General** tab, under the **Certificate Management** section, click the **Import** button.
3. Browse to the location where the **.pfx** certificate is saved and click **Open**.
4. Enter the password for the private key.

5. Click **OK**.\
   \
   If the certificate is valid and suitable for code signing, the import completes successfully.

If the PFX certificate is unsuitable for code signing, the **Certificate Import Failed** dialog will indicate this.

If Publisher detects an existing certificate that is still valid, the **Overwrite Current Certificate** dialog is displayed, warning you and prompting you to click **Yes** to overwrite the existing certificate with the new one. This helps prevent you from accidentally replacing an active and trusted signing certificate.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.patchmypc.com/patch-my-pc-publisher/manage/wsus-updates-tab/wsus-options/certificate-management/manage-certificates/import.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
