Microsoft releases Windows update for printer issue that caused BSODs

Microsoft has distributed a Windows 10 update that should fix an issue with the latest version. Users encountered blue screens of death when printing with various network printers.

It is an ‘out of band’ update, an update that does not come out according to the regular schedule, Microsoft reports. It concerns KB5001567, which should solve the problem with the printers. That issue surfaced after an update last Tuesday.

The problem occurs with Windows 20H2 when a print job is sent to a Windows Server printer. Then users get a blue screen and the message that the PC has crashed with the error APC_INDEX_MISMATCH. The problems occur with printers from Kyocera, Ricoh and Zebra, among others. Updating the printer drivers does not seem to work.

Last Tuesday’s update fixed two print software vulnerabilities: CVE-2021-1640 and CVE-2021-26878. The update is not on the regular schedule, because Microsoft already had a patch Tuesday with a security update for Windows 10 last week.
