The Windows 10 KB5000802 and KB5000808 cumulative updates introduced yesterday are leading to Blue Monitor of Death crashes when printing to network printers.

Yesterday, Microsoft launched the Home windows 10 KB5000802 and KB5000808 cumulative updates as part of the March 2021 Patch Tuesday.

According to posts by procedure administrators on Reddit [1, 2], the Windows 10 crashes began immediately after putting in yesterday’s KB5000802 and KB5000808 updates and making an attempt to print.

“Hey Jen, several individuals around in r/sysadmin, myself incorporated, are looking at a BSOD write-up-update (on at minimum Gain10 20H2 so far) when sending print employment to any Home windows Server printer share employing a variety 3 Kyocera KX driver. (i.e., form 4 KX driver and other generic style 3/4 motorists never exhibit the concern),” 1 Reddit consumer posted.

“KB5000802 broke all Kyocera printing at one of my purchasers. BSOD’s in the exact design as the challenge with printing back in June 2020,” verified a different consumer, whilst stating that none of the typical fixes appear to be doing the job.

Some of the printer manufacturers recognised to be affected, include things like Kyocera, Ricoh, and Dymo.

Working with digital devices that received these updates yesterday, BleepingComputer has rolled back to the March preview updates and is no longer made available the KB5000802 cumulative update like we had been yesterday.

This suggests that Microsoft has pulled the updates from Windows Update although they appear into the concerns. Even so, the updates are nevertheless out there by means of the Microsoft Update Catalog.

Additionally, some of our machines are remaining available the KB4601382 Preview cumulative update released on February 24th, but not yesterday’s KB5000802 update, indicating that a protection update is possible triggering the crashes.

Yesterday, Microsoft launched two protection updates, tracked as CVE-2021-1640 and CVE-2021-26878, to resolve a privilege elevation vulnerability in the Windows Print Spooler.

Microsoft does not incorporate safety updates in the Preview cumulative update provided last thirty day period, which is very likely why end users did not experience the exact same crashes when printing.

Throughout the June 2020 Patch Tuesday updates, a bug was also introduced that prevented people from printing. To solve these printing difficulties, Microsoft launched out-of-band updates for Home windows users.
