February 2026 CU for SharePoint Workflow Manager: Enhancements and Security Updates

Microsoft has released the February 2026 Cumulative Update (CU) for SharePoint Workflow Manager. This update addresses critical issues within both the SharePoint Workflow Manager server and its client components. Ensuring your client components match the server version is crucial for optimal performance. This CU is highly recommended for all SharePoint Workflow Manager users to maintain a stable and secure environment.

This CU focuses on enhancing the stability and reliability of your SharePoint Workflow Manager environments. It includes performance improvements, security patches, and resolutions for known issues. Applying this update is a proactive step in maintaining the health and security of your SharePoint infrastructure.

What's Included in the Update?

The February 2026 CU includes fixes for the following components:

• SharePoint Workflow Manager Server
• SharePoint Workflow Manager Client Components

This update is particularly important for organizations using SharePoint 2016 and SharePoint 2019, where older versions of Workflow Manager have exhibited various issues. The February 2026 CU aims to resolve many of these problems, ensuring smoother workflow execution and improved overall system performance.

How to Install the Update

To install the February 2026 CU, follow these steps:

1. Download the update package from the Microsoft Support website.
2. Run the update package on your SharePoint Workflow Manager servers.
3. Update the SharePoint Workflow Manager client components on client machines.
4. Run the SharePoint configuration wizard.

If you encounter any issues during the update process, consult Microsoft's support resources for assistance. It's always a good idea to test the update in a non-production environment first.

Important Considerations Before Updating

• Before starting the update process, it's critical to back up your SharePoint environment. This will allow you to restore your system to its previous state if any issues arise during the update.
• During the update process, SharePoint services may be temporarily unavailable. Plan your update during off-peak hours to minimize disruption to users.
• After the update, thoroughly test your SharePoint environment to ensure everything is working as expected. Pay close attention to any custom workflows or integrations.

Why You Should Update

Keeping your SharePoint Workflow Manager up to date is crucial for the security and performance of your system. The February 2026 CU offers several key benefits:

• Security: The update includes security patches that protect your SharePoint environment from malicious attacks. Failing to apply these patches can leave your system vulnerable to exploits.
• Performance: The update improves the performance of Workflow Manager, allowing it to run faster and more efficiently. This can lead to significant time savings for users who rely on workflows.
• Stability: The update increases the stability of Workflow Manager, reducing errors and improving overall system reliability. This can prevent unexpected downtime and ensure business continuity.
• New Features: While not always the primary focus of CUs, updates can sometimes introduce new features and functionality to Workflow Manager.

Security patches are particularly important for protecting your organization's data and meeting compliance requirements. By regularly installing updates, you can ensure the security and stability of your SharePoint environment.

Post-Update Configuration

After the update is complete, some additional configuration steps may be necessary. In particular, if you have custom workflows, you'll need to ensure that they are compatible with the new version. You should also review your Workflow Manager settings and adjust them as needed.

For example, you may want to optimize workflow execution times, memory settings, and other performance parameters. These settings should be tailored to the specific needs of your SharePoint environment. Consider using PowerShell scripts to automate these configuration tasks for consistency and efficiency.

The Future of Workflow Manager

While Microsoft continues to support SharePoint Workflow Manager, they are also investing heavily in cloud-based solutions like Power Automate. When choosing a workflow solution for your organization, it's important to consider cloud-based options.

Power Automate is a powerful tool that integrates seamlessly with SharePoint and offers a more modern and flexible workflow platform. If you're planning to migrate to the cloud, Power Automate is a strong contender. Consider a phased migration, starting with less critical workflows to gain experience with the new platform.

Practical Considerations for Enterprise Rollout

When deploying this CU in an enterprise environment, consider these practical points:

• Staged Rollout: Don't deploy to all servers simultaneously. Start with a pilot group to identify potential issues before a full rollout.
• Monitoring: Implement robust monitoring to track workflow performance and identify any errors post-update. Use SharePoint's built-in logging and monitoring tools, or consider third-party solutions.
• Communication: Communicate the update schedule and potential downtime to users in advance. Provide clear instructions on how to report any issues they encounter.
• Rollback Plan: Have a well-defined rollback plan in case the update causes significant problems. This should include detailed steps on how to restore your SharePoint environment to its previous state.

Conclusion

The SharePoint Workflow Manager February 2026 CU is an important update for the security, performance, and stability of your SharePoint environments. It's crucial to install this update as soon as possible and keep your SharePoint environment up to date. If you encounter any issues during the update process, consult Microsoft's support resources.

Remember, an up-to-date SharePoint environment protects your organization's data, optimizes your business processes, and enables your employees to work more efficiently.
