## Remarks

> [!NOTE]
>
> This function isn't safe to call on a time-sensitive thread. For more information, see [Time-sensitive threads](https://learn.microsoft.com/gaming/gdk/docs/gdk-dev/console-dev/overviews/threads/time-sensitive-threads).

This function unregisters the callback function defined by [XStoreGameLicenseChangedCallback](https://docs.xbox.com/reference/system/xstore/functions/xstoregamelicensechangedcallback.md). You will use the same **XTaskQueueRegistrationToken** generated by [XStoreRegisterGameLicenseChanged](https://docs.xbox.com/reference/system/xstore/functions/xstoreregistergamelicensechanged.md) to unregister the callback function. In order to avoid a memory leak each function registered with [XStoreRegisterGameLicenseChanged](https://docs.xbox.com/reference/system/xstore/functions/xstoreregistergamelicensechanged.md) must be unregistered by **XStoreUnregisterGameLicenseChanged** when the callback function is no longer needed.

See [XStoreCreateContext](https://docs.xbox.com/reference/system/xstore/functions/xstorecreatecontext.md) for a usage example.

## Requirements

**Header:** XStore.h (included in XGameRuntime.h)

**Library:** xgameruntime.lib

**Supported platforms:** Windows, XBOX One family consoles and XBOX Series consoles
