taskbarx could not find the handle of the taskbar

If you use Group Policy and your configuration includes taskbar and a full Start layout, users can only make changes to the taskbar. If you use Group Policy and your configuration only contains a taskbar layout, the default Windows tile layout will be applied and cannot be changed by users.

To apply a taskbar configuration that allows users to make changes that will persist, apply your configuration by using Group Policy. If your configuration pins an app and the user then unpins that app, the user's change will be overwritten the next time the configuration is applied. If you use a provisioning package or import-startlayout to configure the taskbar, your configuration will be reapplied each time the explorer.exe process restarts. Apply the layout modification XML file to devices using Group Policy or a provisioning package created in Windows Imaging and Configuration Designer (Windows ICD).Use and Desktop Application Link Path to pin desktop applications.Use and AUMID to pin Universal Windows Platform apps.

Add xmlns:taskbar='' to the first line of the file, before the closing >.You can use AUMID or Desktop Application Link Path to identify the apps to pin to the taskbar.

If you're only configuring the taskbar, use the following sample to create a layout modification XML file.

If you're also customizing the Start layout, use Export-StartLayout to create the XML, and then add the section from the following sample to the file.

The following example shows how apps will be pinned: Windows default apps to the left (blue circle), apps pinned by the user in the center (orange triangle), and apps that you pin using the XML file to the right (green square). In operating systems configured to use a right-to-left language, the taskbar order will be reversed.
