A couple of days ago, Microsoft published a temporary workaround to fix a bug that causes blue screens of death with the APC_INDEX_MISMATCH error code with the latest Windows 10 updates installed. This workaround requires changing some of the printer’s properties using several commands in Command Prompt. Back then, the company promised to release a permanent fix that would automatically solve the annoying problem. This fix is now available to all affected users.
Microsoft today released an out-of-band update to address the printing bug. The affects systems with Type 3 printer drivers and causes a bugcheck whenever a user tries to print a document, webpage, or anything else. If your computer got hit by this bug, Microsoft recommends installing the latest patch. It is available for computers with Windows 10 1803, 1809, 1903, 1909, 2004, and 20H2.
