Windows 10 KB5000802 (March 2021 update) has been going seriously wrong for some PC owners in the last twelve hours, with several users reporting that the botched update is causing Blue Screen of Death errors when they use printers.
To make matters worse, KB5000802 is an automatic security update, which means it has been downloaded and installed automatically for some customers. Users didn’t have a say in whether or not Microsoft should install the update and break their computers with BSOD.
March 2021 cumulative update is proving troublesome for PCs with printers, going by reports on online forums. According to reports, Windows 10 completely crashes and throws up a Blue Screen of Death with stop error code “APC_INDEX_MISMATCH for win32kfull.sys”.
It’s unclear how widespread the issue is, though there are reports of it happening with Ricoh, Zebra, and other printer brands. There are also posts from IT admins on Reddit claiming the update broke all Kyocera printing.
The problem appears when hitting the print button in apps including Notepad and Office. It only occurs when a device is connected to a printer.
“I have tried on several workstations removing wusa /uninstall /kb:5000802 solves the problem. Windows 2004 and 20H2 all up2date seems to have identical BSODs. I have also tried to update drivers to recent KX Universal Printer Driver (v.8.1.1109) but that does not solve the problem,” one Redditor wrote.
If you’re experiencing these issues, the best solution is to uninstall KB5000802/KB5000808 (Settings > Update and Security > Windows Update) and then pausing all updates until Microsoft addresses the problem.
