KB5073722: Overview with user sentiment and feedback

Overview

The January 13, 2026 KB5073722 update is an out-of-band security update for Windows Server 2016 and Windows 10 Enterprise LTSB 2016. This update includes several fixes and improvements, including:- A security hardening behavior that restricts certain applications from autofilling credentials during remote support sessions or automated authentication workflows. This change prevents credential dialogs from responding to virtual keyboard input from remote desktop or screen sharing tools.- The removal of several modem drivers (agrsm64.sys, agrsm.sys, smserl64.sys, smserial.sys) that could cause compatibility issues for modem hardware dependent on those drivers.- An update to the Windows core component WinSqlite3.dll, which was previously detected as vulnerable by some security software.

General Purpose

The main purpose of this KB5073722 update is to address several security and compatibility issues in Windows Server 2016 and Windows 10 Enterprise LTSB 2016. The security hardening change for credential autofill is intended to improve security by preventing certain applications from automatically filling in login credentials, which could be abused by malicious actors during remote access or automated workflows.The removal of the modem drivers aims to eliminate compatibility problems for users with hardware relying on those specific drivers, as they will no longer function after this update.Additionally, the update to the WinSqlite3.dll component resolves a vulnerability that was previously detected by some security software, improving the overall security posture of the affected Windows versions.

General Sentiment

The security hardening for credential autofill is likely to be well-received by security-conscious users and IT administrators, as it helps mitigate potential risks from remote access or automated authentication workflows.However, the removal of the modem drivers may cause some disruption for users who rely on that hardware, as they will need to find alternative solutions or drivers. This could be seen as a negative aspect of the update, especially for those who are heavily dependent on the affected modem functionality.Overall, the update seems to be focused on improving the security and stability of the affected Windows versions, which should be welcomed by most users and administrators.
