+# WindowExtensionContext
+
+The **WindowExtensionContext** module, inherited from [ExtensionContext](js-apis-inner-application-extensionContext.md), is the context environment of the WindowExtensionAbility.
+
+The **WindowExtensionContext** module provides the capabilities of the [WindowExtensionAbility](js-apis-application-windowExtensionAbility.md), including starting the ability.
+
+> **NOTE**
+>
+>  - The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+>
+>  - The APIs provided by this module are system APIs.
+>
+>  - The APIs of this module can be used only in the stage model.
+
+## Usage
+
+Before using the **WindowExtensionContext** module, you must define a child class that inherits from **WindowExtensionAbility**.
+
+```ts
+  import WindowExtensionAbility from '@ohos.application.WindowExtensionAbility';
+
+  let context;
+  class WindowExtAbility extends WindowExtensionAbility {
+    onConnect() {
+      context = this.context; // Obtain a WindowExtensionContext instance.
+    }
+  }
+```
+
+## WindowExtensionContext.startAbility
+
+startAbility(want: Want, options: StartOptions, callback: AsyncCallback&lt;void&gt;): void
+
+Starts an ability. This API uses an asynchronous callback to return the result.
+
+**System capability**: SystemCapability.WindowManager.WindowManager.Core
+
+**Parameters**
+
+| Name| Type| Mandatory| Description|
+| -------- | -------- | -------- | -------- |
+| want | [Want](js-apis-application-want.md)  | Yes| Want information about the target ability.|
+| options | [StartOptions](js-apis-app-ability-startOptions.md) | Yes| Parameters used for starting the ability.|
+| callback | AsyncCallback&lt;void&gt; | Yes| Callback used to return the result.|
+
+**Example**
+
+  ```ts
+  var want = {
+    bundleName: 'com.example.myapplication',
+    abilityName: 'MainAbility'
+  };
+  var options = {
+    windowMode: 102
+  };
+
+  try {
+    this.context.startAbility(want, options, (error) => {
+      if (error.code) {
+        // Process service logic errors.
+        console.log('startAbility failed, error.code: ${JSON.stringify(error.code)}, error.message: ${JSON.stringify(error.message)}');
+        return;
+      }
+      // Carry out normal service processing.
+      console.log('startAbility succeed');
+    });
+  } catch (paramError) {
+    // Process input parameter errors.
+    console.error('error.code: ${JSON.stringify(paramError.code)}, error.message: ${JSON.stringify(paramError.message)}');
+  }
+  ```
+
+## WindowExtensionContext.startAbility
+
+startAbility(want: Want, options?: StartOptions): Promise\<void>
+
+Starts an ability. This API uses a promise to return the result.
+
+**System capability**: SystemCapability.WindowManager.WindowManager.Core
+
+**Parameters**
+
+| Name| Type| Mandatory| Description|
+| -------- | -------- | -------- | -------- |
+| want | [Want](js-apis-application-want.md)  | Yes| Want information about the target ability, such as the ability name and bundle name.|
+| options | [StartOptions](js-apis-app-ability-startOptions.md) | No| Parameters used for starting the ability.|
+
+**Return value**
+
+| Type| Description|
+| -------- | -------- |
+| Promise&lt;void&gt; | Promise that returns no value.|
+
+**Example**
+
+  ```ts
+  var want = {
+    bundleName: 'com.example.myapp',
+    abilityName: 'MainAbility'
+  };
+  var options = {
+  	windowMode: 102,
