Microsoft Urges Millions to Uninstall Latest Windows Update
Microsoft is facing significant backlash after its recent update caused widespread disruptions for Windows users. This January 2026 update, identified as KB5074109, has created numerous problems, particularly affecting Outlook and cloud services. As a response, Microsoft is advising millions of users to uninstall this update to resolve various issues.
Current Issues with the January 2026 Update
The January update for Windows 11 and Windows 10 has been deemed a “nightmare” by users, disrupting functionalities across multiple operating systems. Microsoft acknowledged that classic Outlook profiles using POP accounts and PST files are experiencing severe hang-ups after this update. Users report that Outlook freezes, showing a “Not Responding” message, and struggles to reopen after crashes, often requiring a restart of the system.
Impacted Windows Versions
The update’s effects are not limited to a single version of Windows. The issues arise in:
- Windows 11, version 25H2
- Windows 11, version 24H2
- Windows 11, version 23H2
- Windows 10, version 22H2
- Windows 10 Enterprise LTSC 2021
- Windows 10 Enterprise LTSC 2019
Microsoft’s Recommendations
To mitigate these challenges, Microsoft recommends a few alternatives before fully uninstalling the update:
- Switch to webmail instead of using the Outlook client.
- Store Outlook PST files locally, rather than in OneDrive.
If these options are ineffective, users may need to uninstall the update as a last resort. Microsoft has provided guidance on how to achieve this, though it has cautioned users about the risks involved.
Risks of Uninstalling the Update
While uninstalling the update might resolve the immediate issues, Microsoft has highlighted several potential dangers:
- Increased vulnerability to cyberattacks
- Risk of compromised personal information
- Possibility of data loss
This leaves many users in a difficult position, weighing the need for a functional system against potential security threats.
Conclusion
As Microsoft navigates the fallout from the January 2026 update, users are encouraged to proceed with caution. Local workarounds may temporarily ease the burden, but the specter of security risks looms large for those contemplating the uninstallation of such critical updates. For ongoing guidance and updates, users should remain vigilant and refer back to Microsoft’s official channels.
