New Fixes in This Release

1. This feature enhancement lets you control whether users can copy files from their virtual environments to their user devices:

   When enabled, files and folders on mapped client-drives cannot be added or modified from within the session. Files and folders on mapped client-drives are available in read-only mode only.

   When disabled, files and folders on mapped client-drives are available in read/write mode from within the session. By default, the setting is disabled.

   To enable this feature:

   1. Configure client drive mapping (CDM) to be read-only. In the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdm\Parameters, create a DWORD value with value name ReadOnlyMappedDrive and value data 1.
   2. Configure the server-side clipboard to be read-only. In registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard, create a DWORD value with value name ReadOnly and value data 1.
