    A new update to Windows 10 is causing infamous Blue Screen of Death errors when users connect their computers to printers.

    As reported by Windows Latest, the KB5000802 update – which is an automatic security update as part of the March 2021 package – causes Windows 10 to crash completely with a stop error code that states: “APC_INDEX_MISMATCH for win32kfull.sys”

    One user reportedly said that: “This update seems to be causing blue screens when printing to Kyocera Universal Print drivers. Have had at least 20 confirmed cases from 4 different clients already and it’s only been an hour into the day”.

    Other printer brands, including Kyocera, Ricoh, Zebra, are also affected, leaving Windows 10 to crash whenever users try to print via NotePad, Microsoft’s Office apps, and others.

    Users on Reddit also reported the issue, posting on the r/sysadmin subreddit.

    Microsoft did not immediately respond to a request for comment from The Independent.

    “After installing this update, you might receive an APC_INDEX_MISMATCH error with a blue screen when attempting to print to certain printers in some apps”, the company’s support page reads.

    “We are presently investigating and will provide an update when more information is available.”

    In order to fix the issue, users will need to uninstall the March 2021 package until Microsoft issues a fix. The process to do that can be found under the Control Panel, searching for Programs, then Programs and Features, then “View installed updates” on the left-hand side and finally hitting the button to uninstall “Security Update for Microsoft Windows KB50000802)” or error “KB50000808” for Windows PCs on version 1909.

    A user in the subreddit claiming to be a Microsoft employee has offered workarounds using the Command Prompt, by enabling direct printing or downloading Microsoft’s Application Compatibility toolkit.

    Haha, had same BlueScreen on Wednesday short time after updates.

    But dont have such a printer, only Canon and didnt use it. It occured after plug in hot plug HDD (before I correctly used safely remove devices).

    Had to turn off PC manually, when it came to save error report it didnt move away from 0%, so after a minute I powered off.

    as you say, not related to printer problem (maybe) , just updated PC needed to reboot before you had unplugged / plugged in HDD incorrectly.

    I always make reboot after updates mostly even twice with additional update search in between – it happened after fresh clean OS start.
