Hello
There are a few possible ways to prevent the taskbar from syncing across different devices and operating systems. One way is to use the Group Policy Editor to enable or disable sync settings for specific users or groups. You can do this by following these steps:Press the Windows + R keyboard shortcut to open the Run dialog box. Type gpedit.msc in the text box and hit OK.When the User Account Control (UAC) prompt appears, select Yes to proceed.Use the left pane to navigate to the following folder: Computer Configuration > Administrative Templates > Windows Components > Sync your settings.In the right pane, double-click on Do not sync and select Enabled or Disabled as per your preference. Click OK to save the changes.Repeat the same steps for User Configuration > Administrative Templates > Windows Components > Sync your settings.Anther way is to customize the taskbar layout using an XML file and deploy it using a Mobile Device Management (MDM) provider such as Microsoft Intune or Configuration Manager. You can use an existing XML file or create a new one. You can add apps to the taskbar using their Application User Model ID (AUMID) or Desktop Application Link Path. You can also remove default pinned apps and order the apps as you like.
