Quote:The Windows 10 KB5000802 and KB5000808 cumulative updates released yesterday are causing Blue Screen of Death crashes when printing to network printers.
 
Yesterday, Microsoft released the Windows 10 KB5000802 and KB5000808 cumulative updates as part of the March 2021 Patch Tuesday.
 
Since then, there has been a constant stream of complaints that printing is causing Windows 10 to crash with an "APC_INDEX_MISMATCH for win32kfull.sys" blue screen of death crash.
 
According to posts by system administrators on Reddit [1, 2], the Windows 10 crashes began immediately after installing yesterday's KB5000802 and KB5000808 updates and attempting to print.
 
"Hey Jen, several folks over in r/sysadmin, myself included, are seeing a BSOD post-update (on at least Win10 20H2 so far) when sending print jobs to any Windows Server printer share using a type 3 Kyocera KX driver. (i.e., type 4 KX driver and other generic type 3/4 drivers don't exhibit the issue)," one Reddit user posted.
 
"KB5000802 broke all Kyocera printing at one of my clients. BSOD's in the same style as the problem with printing back in June 2020," confirmed another user, while stating that none of the normal fixes appear to be working.
 
Some of the printer brands known to be affected, include Kyocera, Ricoh, and Dymo.
