Windows 11 computer can't access Windows 10 printer after Patch Tuesday update

First off, the computer that's connected to the printer has a Windows 10 IoT Enterprise LTSC 2021 OS, which is on the a 21H2 lane.

The computer that is trying to add the printer connected to the Windows 10 computer is a Windows 11 IoT Enterprise LTSC 2024 OS, which is on a 24H2 lane.

Both are receiving updates.

Since this past Tuesday, the Windows 11 computer cannot add and print from the Windows 10 computer, with the error message stating that it's a 0x0000011b error.

I did add the REG file made by @garlin before that and it was printing, until now.

Has anyone been witnessing the same problem, or am I the only witness?

Courtesy of co-pilot THIS WORKED FOR ME., This is a known problem when there is a mix of 10 and 11 on the same network. This is the registry fix that has fixed it for most folks. Apply this fix to ALL computers on the network. Then restart the print spooler service. Since cumulative updates seem to break this fix frequently, create either the batch script or the power shell script and save it so you can manually run it easily next time OR you can set it to run automatically after every patch Tuesday. That way you don't have to remember to do it .

THIS IS COPIED DIRECTLY FROM CO-PILOT'S INSTRUCTIONS

Here are two options: Batch script (simple) and PowerShell script (more robust).

🖥Batch Script (quick and easy)

Using Notepad. Copy & paste the following. Save the file as FixPrinterError.bat and change it's properties to run it as Administrator: (You have to change "save as file type" to all files in order to make it a .bat file),


@echo off

echo Applying 0x0000011b printer fix...

:: Add registry key

reg add "HKLM\SYSTEM\CurrentControlSet\Control\Print" /v RpcAuthnLevelPrivacyEnabled /t REG_DWORD /d 0 /f

:: Restart Print Spooler

net stop spooler

net start spooler

echo Done! Please try reconnecting to the shared printer.

pause

PowerShell Script (recommended)

Using Notepad, Copy & copy & paste the following. Save the file as FixPrinterError.ps1 and change it's properties to run it as Administrator.
(You have to change "save as file type" to all files in order to make it a .ps1 file),


Write-Host "Applying 0x0000011b printer fix..." -ForegroundColor Cyan

# Add registry key

New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Print" `

-Name "RpcAuthnLevelPrivacyEnabled" -PropertyType DWord -Value 0 -Force

# Restart Print Spooler

Restart-Service -Name Spooler -Force

Write-Host "Fix applied. Try reconnecting to the shared printer." -ForegroundColor Green

Safety Notes

• Run these scripts on both computers (the one sharing the printer and the one connecting).
• Always run as Administrator.
• After Windows updates, re-check that the registry key still exists — updates sometimes reset it.

To automate this fix so it runs automatically after every Patch Tuesday update using Task Scheduler. That way, you won’t have to remember to reapply it manually.

🛠 Step-by-Step: Automating the Fix

1. Save Your Script

• Use either the Batch (FixPrinterError.bat) or PowerShell (FixPrinterError.ps1) script I gave you earlier.
• Place it somewhere safe, e.g. C:\Scripts\FixPrinterError.ps1.

2. Open Task Scheduler

• Press Windows + R, type taskschd.msc, and hit Enter.
• In the left pane, select Task Scheduler Library.

3. Create a New Task

• Click Action > Create Task.
• Give it a name like: AutoFixPrinterError.

4. Set the Trigger

• Go to the Triggers tab → New.
• Choose Monthly.
• Select The second Tuesday of every month (this is Patch Tuesday).
• Click OK.

5. Set the Action

• Go to the Actions tab → New.
• Choose Start a program.
• If using Batch:
  • Program/script: C:\Scripts\FixPrinterError.bat (or replace this with whatever folder path you chose to use)
• If using PowerShell:
  • Program/script: powershell.exe
  • Add arguments:

-ExecutionPolicy Bypass -File "C:\Scripts\FixPrinterError.ps1"
(or replace this with whatever folder path you chose to use)

• Click OK.

6. Set Conditions

• In Conditions, uncheck “Start only if the computer is on AC power” if you want it to run regardless.
• In Settings, check “Run task as soon as possible after a scheduled start is missed.”

7. Run as Administrator

• In the General tab, check Run with highest privileges.
• This ensures the registry edit and spooler restart succeed.

Now, every Patch Tuesday, your system will automatically apply the registry fix and restart the spooler service. That means no more manual steps or printer headaches after updates.

After a few weeks, the problem has returned, but under a different error code: 0x00000709.

When connecting to a printer shared by a Windows 11 computer from a Windows 10 computer, the error code presents itself as 0x00000709 (I don't know how many zeroes are there exactly!) and the message on the Windows 10 PC says "Operation cannot be completed." Here's what I tried so far:

- adding LPD and LPR in features
- adding @garlin 's reg file; I did that to both computers
- overriding RPC settings to Named Pipes and enabling Print Browsing, both in Group Policy Editor
- changing the name of the Device setting in HKEY_CU\Software\Windows NT\CurrentVersion\Windows into the share name of the printer
- modifying Windows folder permissions from the last point, adding Full Control permissions to Everyone
- restarting the Print Spooler every time I configure settings

Of course, I know fooling around with system files is not wise, but I'm grasping at straws. Windows 10 is for my mother and she has to put it in her room with a USB wireless network dongle. As such she cannot share the printer as it is in a room across the Windows 11 computer and the printer attached. Don't ask.

The computer sharing the printer is a Windows 11 IoT Enteprise LTSC 2024 edition and my mother's computer is a Windows 10 IoT Enterprise LTSC 2021 edition. Both are updated since the last November patch Tuesday.
