Hi Ross Nishuler,
To ensure your users retain their manually selected default printer in a Windows Server 2025 RDSH environment, you must address both the Remote Desktop connection behavior and the operating system's internal print management. First, open the Group Policy Editor on your session hosts and navigate through Computer Configuration, Administrative Templates, Windows Components, Remote Desktop Services, Remote Desktop Session Host, and Printer Redirection. Enable the policy named Do not set default client printer to be default printer in a session. This prevents the server from automatically pulling the physical endpoint's default printer and overriding the session setting upon connection.
Next, you must disable the Windows feature that dynamically changes the default printer based on the user's recent print activity. Open the Registry Editor and navigate to HKEY_CURRENT_USER, Software, Microsoft, Windows NT, CurrentVersion, Windows. Create or modify a DWORD value named LegacyDefaultPrinterMode and set it to one. This reverts the system to strictly honoring the user's manual printer selection. Finally, ensure your profile management system, such as FSLogix or User Profile Disks, is properly capturing and roaming the user registry hive so these settings persist across logoffs and new sessions in your farm.
