Tech Desk — January 25, 2026:
Windows 11 users are facing another disruptive update as KB5074109 (build 26200.7623) triggers widespread system issues. Following reports of app errors, black screens on NVIDIA GPU devices, and Outlook hangs for POP accounts or PST files on OneDrive, Microsoft has now recommended uninstalling the update to restore system stability.
The problematic update was part of the January 2026 Security Update rollout for versions 25H2 and 24H2. While some workarounds exist—such as using the Outlook web app or relocating PST files—Microsoft warns they may be complicated for average users, making uninstallation the safest immediate solution.
This incident adds to a series of recent Windows Update headaches, including Out-of-band patch KB5077744 for Remote Desktop sign-in issues and emergency updates for the now-out-of-support version 23H2 to fix shutdown failures. Such recurring problems raise concerns about Microsoft’s quality control and update reliability in 2026, frustrating users who depend on Windows 11 for work and productivity.
For affected users, uninstalling KB5074109 is straightforward:
Open Settings → Windows Update and click Pause for 1 week to prevent reinstallation.
Go to Update History → Uninstall Updates under Related Settings.
Select KB5074109 and click Uninstall, then restart your PC.
Until Microsoft releases a stable replacement, rolling back the update is the recommended approach, highlighting the ongoing tension between timely security updates and maintaining system stability.
