Microsoft's Windows 11 24H2 Update Breaks Scanners

Microsoft's latest Windows 11 24H2 update has rendered many users' scanners unusable. Despite Microsoft claiming to have fixed an issue with the eSCL scan protocol, numerous Canon users are still experiencing problems, with their multifunction devices failing to scan properly on Windows 11 unless connected via wired Ethernet. Canon has confirmed the issue and says Microsoft is working on a fix, expected in January 2025. Affected users can use the built-in Windows Fax and Scan app as a workaround. This highlights the compatibility challenges that can arise from major OS updates.
