Always Show All Icons And Notifications On The Taskbar GPO

The GPO setting to Always show all icons and notification on the taskbar is actually a group policy preference. To always show all icons and notifications on the taskbar, create a Group Policy Preference to create the following registry setting:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

Create a new DWORD called EnableAutoTray and set the value to 0

The GPO preference should be created as a user group policy, or a computer one with loopback policy enabled.
