Summary

Microsoft's January 2026 update intentionally removed drivers.
Affected users face costly modem replacements.
Dial-up users are primarily in remote areas.

Microsoft's January 2026 Windows 11 update has intentionally rendered numerous dial-up modems inoperable. The KB5074109 patch removed specific driver packages identified by Microsoft as "unsafe" due to unpatched security vulnerabilities. This intentional removal, detailed in official release notes, has disrupted internet access for users still relying on dial-up technology.

Many of these affected users are located in remote areas of the United States, where dial-up remains a primary or sole option for internet connectivity due to limited broadband availability. The abrupt removal of necessary driver packages occurred without prior notification to manufacturers or end-users, forcing many into immediate and unexpected modem replacements that can be costly.
