APC_INDEX_MISMATCH stop error | Windows 10 BSOD | Blue Screen of Death

Today, I received a call from one of our respected user and found that he is not able to print. Upon investigation, I found that he was getting the infamous Blue Screen Of Death error when he was hitting CTRL+P. The system restarted automatically. I found that that it was due to one the Windows Update that was rolled out in March 2021 which was the root cause.

Below are the steps that I took to resolve the issue. Hope it will help you too.

  1. Solution 1
    1. Based on the below article published by Microsoft, we tried to run the below commands but it did not work as intended.

      2. rundll32 printui.dll,PrintUIEntry /Xs /n “KX driver for Universal printing” attributes +direct

          After installing KB5000802, you might receive an APC_INDEX_MISMATCH error with a blue screen when attempting to print to certain printers in some apps. This issue affects a subset of Type 3 printer drivers and does not affect printer drivers that are Type 4. If you are unsure which type your printer driver is, use the following steps:
          1. Press the Windows key+r or select Start and type run and select it.
          2. Type printmanagement.msc and press enter or select the OK button.
          3. If Print Management opens, continue to step 4. If you receive the error, Windows can not find ‘printmanagement.msc’. then select Start and type manage optional features and select it. Select Add a Feature and type print, select the check box next to Print Management Console and select install. You will now need to start at step 1 again.
          4. Expand Print Servers, expand your computer’s name, and select Printers.
          5. You can now see the Driver Type for each of your installed printer drivers.
          Workaround: To mitigate the issue, follow the instructions in this video. The Command Prompt commands from the video are as follows (you will need to replace KX driver for Universal printing with the name of your printer, as explained in the video):
          • rundll32 printui.dll,PrintUIEntry /Xg /n “KX driver for Universal printing”
          • rundll32 printui.dll,PrintUIEntry /Xs /n “KX driver for Universal printing” attributes +direct
          Affected platforms:
          • Client: Windows 10, version 20H2; Windows 10, version 2004; Windows 10, version 1909; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10, version 1803
          • Server: Windows Server, version 20H2; Windows Server, version 2004; Windows Server, version 1909; Windows Server, version 1809; Windows Server 2019; Windows Server, version 1803
          Next steps: We are working on a resolution and estimate a solution will be available in the coming week.
  2. Solution 2
    1. Uninstall the update KB5000802 | March 9, 2021—KB5000802 (OS Builds 19041.867 and 19042.867)
      1. Click the Start button, then click the Settings. Once the Settings app opens, click Update & Security. From the list in the centre of the window, click “View update history,” then “Uninstall updates” in the top-left corner.
      2. Scroll down to the Microsoft Windows section, then click on the update at the top of the list. It should be the one with the most recent install date. Take a note of its full name and Knowledge Base (KB) number, as these might come in useful later. If you can’t find and update and know its name or KB number, you can use the search box in the top-right corner to find it.
