<?xml version="1.0" encoding="utf-8"?> <LayoutModificationTemplate xmlns="http://schemas.microsoft.com/Start/2014/LayoutModification" xmlns:defaultlayout="http://schemas.microsoft.com/Start/2014/FullDefaultLayout" xmlns:start="http://schemas.microsoft.com/Start/2014/StartLayout" xmlns:taskbar="http://schemas.microsoft.com/Start/2014/TaskbarLayout" Version="1"> <CustomTaskbarLayoutCollection PinListPlacement="Replace"> defaultlayout:TaskbarLayout taskbar:TaskbarPinList <taskbar:UWA AppUserModelID ="Microsoft.CompanyPortal_8wekyb3d8bbwe!App"/> <taskbar:UWA AppUserModelID ="MicrosoftTeams_8wekyb3d8bbwe!App"/> </taskbar:TaskbarPinList> </defaultlayout:TaskbarLayout> </CustomTaskbarLayoutCollection> </LayoutModificationTemplate>
