Windows 10 task bar customization

I have customized the task bar and I need that to be available to all the user profile the same.

This is the original one

I want this to be like this

I modified the xml file to be as below

xmlns:taskbar="http://schemas.microsoft.com/Start/2014/TaskbarLayout"
CustomTaskbarLayoutCollection PinListPlacement="Replace">
<defaultlayout:TaskbarLayout>
<taskbar:TaskbarPinList>
      <taskbar:UWA AppUserModelID="Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge" />
      <taskbar:DesktopApp DesktopApplicationLinkPath="%APPDATA%\Microsoft\Windows\Start Menu\Programs\System Tools\File Explorer.lnk" />
</taskbar:TaskbarPinList>
</defaultlayout:TaskbarLayout>
</CustomTaskbarLayoutCollection>

Unfortunately I tried adding this to the local group policy and pointed it to this location where the xml file has been copied but it does not apply to all users. I even copied it individually to each users profile 

This is default profile where I have the file startmenbarlayout.xml and in each individual users profile in the same location but still it does not get applied. What could be wrong or where am I going wrong. I Need to have this ready today. Appreciate anyone please let me know what could be wrong with my xml file or where I am applying.
