In release 1607 of Windows 10, Microsoft has now introduced a way to configured the Windows 10 taskbar using Group Policy. This feature allows Group Policy administrator to now add or replace the application that appear on the taskbar. This actually is the first time since Windows Vista that a Group Policy administrator has been able to configure the taskbar for a user. Before this you could only configure it by modifying the default users profile, but user would then be able to remove and reconfigured the taskbar however they wanted.
To implement this feature you need to first create an XML file that has the required configuration information. This is actually just an addition to the same XML file you might already have deployed to configure your start menu. In fact the policy setting to apply the taskbar settings is the exact same “Start Layout” policy setting under “Users\Administrator Templates\Start Menu and Taskbar” that was introduced in Windows 8.1.
Once you have configured the XML then save it to a network share that has “Authenticated Users” read permission and then point the policy setting to use the XML file you saved at this location.
Below is an example XML that will apply Paint, Microsoft Mail and Command Prompt to the taskbar.
<?xml version=”1.0″ encoding=”utf-8″?>
<taskbar:DesktopApp DesktopApplicationLinkPath=”%ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\Accessories\Paint.lnk” />
<taskbar:UWA AppUserModelID=”microsoft.windowscommunicationsapps_8wekyb3d8bbwe!microsoft.windowslive.mail” />
<taskbar:DesktopApp DesktopApplicationLinkPath=”%appdata%\Microsoft\Windows\Start Menu\Programs\System Tools\Command Prompt.lnk” />
As you can see the Microsoft Windows Live Mail is a Universal Windows Application, if you want to pin another UWA like this you can pin it to your start menu and then use the “Export-StartLayout” PowerShell command to get the exact AppUserModelID value for the app you want to pin.
So now you have the XML you want to use and you want to apply it simply configured and apply the “Start Layout” policy (as per above) to the user and they will now get the apps pin’d to the taskbar next time they logon.
Note that even though you have added the pinned items to the taskbar you should be aware that they can still un-pin these items. Unlike other policy settings however, they will not come back after the next Group Policy refresh. Instead they will only come back once the XML modification date is changed. The easiest way to do this is to simple open then XML configuration file on the central server and then just save the un-modified file. Note: This feature does not allow you to remove the “Cortana” and “Task View” items using this feature.
