 ## App groups
 
-An app group is a logical grouping of applications installed on session hosts in the host pool. An app group can be one of two types:
+An app group is a logical grouping of applications installed on session hosts in the host pool.

+An app group can be one of two types: 
 
-By default, a desktop app group (named "Desktop Application Group") is automatically created whenever you create a host pool. You can remove this app group at any time. However, you can't create another desktop app group in the host pool while a desktop app group exists. To publish RemoteApps, you must create a RemoteApp app group. You can create multiple RemoteApp app groups to accommodate different worker scenarios. Different RemoteApp app groups can also contain overlapping RemoteApps.

+Each host pool has a preferred app group type that dictates whether users see RemoteApp or Desktop apps in their feed if both resources have been published to the same user. By default, Azure Virtual Desktop automatically creates a Desktop app group named "Desktop Application Group" whenever you create a host pool and sets the host pool's preferred app group type to **Desktop**. You can remove the Desktop app group at any time. If you want your users to only see RemoteApps in their feed, you should set the **Preferred App Group Type** value to **RemoteApp**. You can't create another Desktop app group in the host pool while a Desktop app group exists.

-- We don't support assigning both the RemoteApp and desktop app groups in a single host pool to the same user. Doing so will cause a single user to have two user sessions in a single host pool. Users aren't supposed to have two active user sessions at the same time, as this can cause the following things to happen:
-    - The session hosts become overloaded
-    - Users get stuck when trying to login
-    - Connections won't work
-    - The screen turns black
-    - The application crashes
-    - Other negative effects on end-user experience and session performance
-- A user can be assigned to multiple app groups within the same host pool, and their feed will be an accumulation of both app groups.
-- Personal host pools only allow and support RemoteApp app groups.

 ## Workspaces
 
 A workspace is a logical grouping of application groups in Azure Virtual Desktop. Each Azure Virtual Desktop application group must be associated with a workspace for users to see the remote apps and desktops published to them.
 
 ## End users
 
-After you've assigned users to their app groups, they can connect to a Azure Virtual Desktop deployment with any of the Azure Virtual Desktop clients.
