Earlier this week, Microsoft rolled out various security updates as part of its monthly Patch Tuesday update cycle. Unfortunately, one of the updates is causing havoc. Windows Latest reports the KB5000802 update for Windows 10 is crashing some users' systems.

KB5000802 results in BSODs when using network printers

Users report sending a print job to a Windows Server printer results in a Blue Screen of Death (BSOD). The issue affects Windows 10 version 20H2 and can't be resolved by updating printer drivers.
The most worrying thing is that Windows 10 simply crashes when users try to print via Notepad, Office and other apps. This happens only when your device is using an affected printer/printing driver.
Affected printers include models from Kyocera, Ricoh, Zebra, and others. It seems KB5000802 broke something in win32kfull.sys. Until there's an official fix from Microsoft, users can uninstall the KB5000802 update via Windows Update to resolve the issue.

Windows 10 version 1909 also seems affected -- in this case it's KB5000808 that's causing issues.
