modem drivers

About this tag
Discussions about modem drivers on WindowsForum.com focus on Microsoft's January 2026 cumulative updates for Windows 11, which removed four legacy modem drivers from the in-box image due to high-severity vulnerabilities. This removal broke modem-based telephony and POS appliances for some users, forcing them to uninstall the update and pause updates to restore functionality, at the cost of reintroducing security risks. The threads cover the security versus compatibility trade-off, workarounds, and the broader impact on affected systems. No other modem driver topics appear in the tagged content.
