Install Every Pending Update

If you still have pending updates on your Windows 11/10, it’s recommended that you first make sure you’re using the latest patches. The steps are as follows;

Step 1: Press the Win + R key to open the Run dialog box. Then type ms-settings:windowsupdate and press Enter to open the Windows Update page.

Step 2: Go to the right menu and click Download now if a new update is available. If there are no pending updates, click Check for Updates to trigger a scan.

Step 3: Wait until each pending update is installed, then restart your PC and wait until the next boot is complete.

After that, you can check if the error 0x0000011b exists.

Uninstall recent Windows updates

remove the september cumulative update from microsoft. This patch was to fix Print Nightmare, and it caused this. We have removed this patch on all our print servers for the time being. There are a number of mitigation efforts for it, but MS has not fully published what we have to do with this patch in place yet. Some people with premier support are getting info, but nothing available published to the masses yet. I uninstalled KB5005565 but now I’m getting error 0x000003e3 trying to re-add the printer. I should have not removed it and it probably would have worked. I’m hoping a patch comes out on Tuesday, but ultimately I think I’m going to install a StarTech Parallel Ethernet Network Print Server on this Epson LX-350 because I don’t trust that Microsoft will get this right.

If error code 0x0000011b started occurring after installing the latest Windows updates, uninstall them and see if this helps. Many Windows 11 users confirmed that uninstalling KBKB5005565 and KB5005568 fixed the problem.
