Network printing destroyed on first-ever Win 11 update

The very first cumulative update for Windows 11 broke network printing. Shared printers failed with errors 0x000006e4, 0x0000007c, and 0x00000709 — an impressive trio of error codes for what should be a basic network operation. This was part of the ongoing PrintNightmare saga, where Microsoft’s attempts to patch a print spooler vulnerability kept breaking printing itself. The fix arrived nine days later with KB5006746. Windows 11 was barely a week old when its first update proved that the tradition of Patch Tuesday breaking things would continue uninterrupted on the new operating system.
