# Windows OCR

### Supported languages

{% hint style="info" %}
The default language used will be based on your Windows system language (OCR language packs are available for install)
{% endhint %}

Windows OCR can only recognize languages that have the OCR language pack installed

The list can be obtained via **PowerShell** by running the following commands:

```
[Windows.Media.Ocr.OcrEngine, Windows.Foundation, ContentType = WindowsRuntime]
```

```
[Windows.Media.Ocr.OcrEngine]::AvailableRecognizerLanguages
```

### How to query for OCR language packs <a href="#how-to-query-for-ocr-language-packs" id="how-to-query-for-ocr-language-packs"></a>

To return the list of support language packs, open **PowerShell** as an Administrator (right-click, then select "Run as Administrator"), and enter the following command:

```
Get-WindowsCapability -Online | Where-Object { $_.Name -Like 'Language.OCR*' }
```

An example output:

```
Name  : Language.OCR~~~en-GB~0.0.1.0
State : NotPresent

Name  : Language.OCR~~~en-US~0.0.1.0
State : Installed

Name  : Language.OCR~~~ja-JP~0.0.1.0
State : NotPresent
```

{% hint style="info" %}
The language and location is abbreviated, so "en-US" would be "English-United States" and "en-GB" would be "English-Great Britain". If a language is not available in the output, then it's not supported by OCR.
{% endhint %}

### How to install an OCR language pack <a href="#how-to-install-an-ocr-language-pack" id="how-to-install-an-ocr-language-pack"></a>

The following commands install the OCR pack for "ja-JP":

```
$Capability = Get-WindowsCapability -Online | Where-Object { $_.Name -Like 'Language.OCR~~~ja-JP~0.0.1.0' }
```

```
$Capability | Add-WindowsCapability -Online
```

## 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.vntranslator.com/user-guide/ocr/ocr-engines/windows-ocr.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.
