  1. For everyone having issues with this update, here is a workaround solution from Microsoft employee on Microsoft Answers:

    If you are running into a problem APC_INDEX_MISMATCH BSOD while printing, I recommend trying out these steps to mitigate the issues until Microsoft addresses the problem with the update.

    Section 1 – Enable Direct Printing. This should allow 32bit apps to print on 64bit OS without crashing.

    Identify the name of your printer. E.g., “Kyocera TASKalfa 820 KX”

    In an elevated command prompt, run rundll32 printui.dll,PrintUIEntry /Xg /n “Kyocera TASKalfa 820 KX”. If Direct appears on the line of attribute:, that means direct printing has been turned on and you had the right settings – stop here and proceed to section 2.

    Note – replace the Kyocera TASKalfa 820 KX text with your printer’s name

    If Direct setting is not on, in an elevated command prompt, run rundll32 printui.dll,PrintUIEntry /Xs /n “Kyocera TASKalfa 820 KX” attributes +direct

    Note – replace the Kyocera TASKalfa 820 KX text with your printer’s name

    Often times, apps like Acrobat and OpenOffice runs as 32bit apps and this should be enough to workaround around the problem until Microsoft addresses the issue. But this will not solve the problem for 64bit applications printing on 64bit OS, nor 32bit applications printing on 32bit OS.

    Section 2 – Enable PrintIsolationAware appcompat fix to your printer. This should allow 64bit applications printing on 64bit OS and 32bit applications printing on 32bit OS without crashing.

    Follow the directions from the following page to acquire the Application Compatibility Tookit Download: Application Compatibility Toolkit (ACT) for Windows 10. | Microsoft Docs

    Follow the instructions – Creating a Custom Compatibility Fix in Compatibility Administrator (Windows 10) – Windows Deployment | Microsoft Docs – to use the Compatibility Administrator tool to apply the “PrinterIsolationAware” fix to the affected application

  2. I have to roll back my Windows 10 to 844. This update is no good.

    This is why everyone hates Windows Updates

  3. Bsod occurring pretty much instantly when printing to a Kyocera machine ‌(APC‌ ‌mismatch‌ ‌index‌ ‌/‌ ‌win32kfull.sys)

    1. Faiz Tech says:

      When the LCU is installed on a system with a lousy kyocera printer and you print, you get a blue screen BSOD, its actually not the update itself.
