## 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).</Note>

The association between user and device can change for many reasons:

* The user signs out from the console.
* Someone uses the input device to select a different user in the Account Picker.

To receive a notification when the user-device association changes, call [XUserRegisterForDeviceAssociationChanged](/reference/system/xuser/functions/xuserregisterfordeviceassociationchanged) to get an [XUserDeviceAssociationChangedCallback](/reference/system/xuser/functions/xuserdeviceassociationchangedcallback).

<Note>*XUserFindForDevice* cannot return a user handle to a user that hasn't been signed in with a call to [XUserAddAsync](/reference/system/xuser/functions/xuseraddasync). See [Users and input devices](/build/core-features/common/user/users-input-devices) for more information.</Note>

## Requirements

**Header:** XUser.h

**Library:** xgameruntime.lib

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