Microsoft changed the default print related communication for client server communications in Windows 11 version 22H2.

windows 11 2022 network printer

Systems use RPC over TCP by default on Windows 11 version 22H2 devices and no longer RPC over Named Pipes. The change may affect how Windows devices communicate during printing and printing related operations.

It should not have an impact on most Home setups, where printers are connected directly to a Windows PC. Windows organizations and users who print over a network, e.g., using a dedicated print server or connections to another computer for printing, may have run into issues after upgrading the client to the Windows 11 2022 Update because of the change.

Microsoft states that the switch improves the "overall security of printing in Windows" by enforcing "newer and more secure communication methods".  By default, clients and servers listen for incoming connections using RPC over TCP.

Options to customize print related communications are provided for administrators. Administrators may change the default configuration using the Group Policy or the Windows Registry; this includes switching to RPC over Named Pipes for printing communication and configuring the spooler server to also listen for RPC over Named Pipes communication.

Microsoft published a support document that provides administrators with guidelines to change the default way printers communication on Windows 11 version 22H2 devices.

Here are instructions for using RPC over Named Pipes:

Use RPC over Named Pipes for client – server communication

Enable by using Group Policy:

  • Path: Computer Configuration > Administrative Templates > Printers > Configure RPC connection Settings
  • Enable and set to RpcOverNamedPipes.

Enable the setting by using the registry:

  • Run reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\RPC" /v RpcUseNamedPipeProtocol /t REG_DWORD /d 1 /f

Enable listening for incoming connections on RPC over Named Pipes

Enable via Group Policy:

  • Path: Computer Configuration > Administrative Templates > Printers > Configure RPC listener settings
  • Enable and set protocols allowed to be used to RpcOverNamedPipesAndTcp.

Enable the setting via the registry:

  • Run reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\RPC" /v RpcProtocols /t REG_DWORD /d 0x7 /f

Use a specific port for RPC over TCP communication (Max port: 65535)

Enable via Group Policy:

  • Path: Computer Configuration > Administrative Templates > Printers > Configure RPC over TCP port Enable and set the port number

Enable the setting via the registry

  • Run reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\RPC" /v RpcTcpPort /t REG_DWORD /d <port number> /f

Enforce Kerberos authentication

Enable via Group Policy:

  • Path: Computer Configuration > Administrative Templates > Printers > Configure RPC listener settings
  • Enable and set the authentication protocol allowed to be used to Kerberos.

Enable the setting via the registry

  • Run reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\RPC" /v ForceKerberosForRpc /t REG_DWORD /d 1 /f

Administrators may customize the default printing behavior to restore the status quo..

      It worked for me just fine. You’re probably not following the instructions clearly.

    Is this cut and paste from a Microsoft PR paper, because it 1000% BS:

    “By listening to user insights, Microsoft has demonstrated its commitment to refining the Windows experience based on real-world needs.”

    Windows 11 is proof they don’t give a s*it.

      I agree! Windows 11 was a downgrade to me and I kept all 8 computers in our family on Windows 10 as a result. They didn’t listen to any customers. The taskbar was THE main reason I stayed away from Windows 11. With 6 monitors, it is impossible to navigate so many browser tabs, without the feature. I will try the new version in the virtual box to see if it is worth it yet.

    Microsoft did a terrible job with this implementation.

    They simply need to employ the creator of StartAllBack to fix Windows. He is smarter and more talented than the entire campus of Microsoft employees.

      @ MarineRecon,

      Be careful which Linux distro you choose. Some of them don’t include the Wayland protocol which is a security issue i.e. apps can copy, paste and inject data without user interaction.

      It’s included in Fedora: https://docs.fedoraproject.org/en-US/fedora/latest/system-administrators-guide/Wayland/

      Definitely NOT! Once you get older and your eyesight starts to fail you’ll positively loathe dark mode.

        Not sure what eye problems *you’re* having, but for me the exact opposite is true. Dark Mode is MUCH easier on my Eyes.

        BTW- I’m 52, and have worked in IT all my life. Been staring at monitors for hours each day, most days of the week since the late 1980’s.

    I presume the text “WindowsCopilot,,” is a typographical error (2023/09/17/how-to-disable-windows-copilot-in-windows/). The broken comment system unfortunately looks like it is populating itself via AI autopilot.

    Hopefully, this Windows Copilot nonsense fails even more spectacularly than Cortana. Who requested this? We want all of the UX features removed back in 11, not this copilot nonsense.

    I really don’t mind all of these Windows enhancement but Microsoft get one thing very wrong. ‘Opt in’, is far better than seek information and work to disable.

    Turn off Windows Copilot entirely is not good enough.

    With that snake oil salesman Panos gone, hopefully Windows can return to a normal desktop operating system without all the insanity it has right now in Windows 11.

    @ Martin,

    Does your gpedit hack also turn off all the other “subscribed content” shown in the registry screenshot? Do you happen to know what all those are?

    I wish I had read this article a few months ago, as I purchased two refurbished Windows 10 Pro PCs to replace two older ones. The 1st one I entered an existing Microsoft account I had and it imediately setup OneDrive, adding it to the path names for the common folders such as Documents, Music, video, etc. I tried to just disable OneDrive but then had odd problems finding my data copied from another older PC. long story short I was able to remove all the entries from the registry after un-installing OneDrive.
    The second refurbished PC I didn’t connect the WiFi adapter so during installation I was able to click on the no Internet option. Basically I did as you suggested above; set up a local login, disabled OneDrive from running on bootup, and eventually unInstalled it. No problems with folder paths, etc.

    The registry option worked for me, but only me, not any other users. How do I make this apply to all users? Yes, I have admin rights.
