Windows 10 LTSC 2021 End Date in 2027

Windows 10 LTSC 2021 End Date in 2027

Windows 10 Enterprise LTSC 2021 will reach its end of support in 2027, marking the end of regular security updates for this version. Extended Security Updates (ESU) will be available for purchase starting September 1, 2026, to provide critical and important security updates for an additional year.

What is Changing in 2027

In 2027, Windows 10 Enterprise LTSC 2021 will reach its end of support, meaning devices running this version will no longer receive regular security updates ^[1]. This means that any vulnerabilities found after the end of support date will not be patched, leaving your business systems at risk ^[5]. ESU coverage will be available for purchase starting September 1, 2026, but it will only provide critical and important security updates, not new features or quality fixes ^[1].

What it Means for Your Business

The end of support for Windows 10 Enterprise LTSC 2021 in 2027 will have significant implications for businesses relying on this version. Without regular security updates, your systems could become vulnerable to cyber threats, potentially leading to data breaches or system failures. Additionally, compliance with industry standards may become more challenging as your systems fall out of line with current security practices. To mitigate these risks, it is crucial to plan ahead and consider transitioning to a supported version of Windows or another operating system.

Immediate Risks

• Increased Vulnerability: After the end of support, your systems will be exposed to new vulnerabilities without the protection of regular security updates.
• Compliance Issues: Many industries require regular security updates to maintain compliance with regulations such as GDPR, HIPAA, or PCI-DSS.
• Operational Disruptions: System failures or data breaches can disrupt business operations and lead to financial losses.

Long-term Consequences

• Higher Costs: Extended Security Updates are expensive and the cost doubles every consecutive year, making it financially unsustainable in the long run.
• Limited Functionality: ESU does not include new features, quality fixes, or design change requests, which can limit the capabilities of your systems.
• Strategic Disadvantage: Relying on outdated systems can hinder your ability to innovate and stay competitive in the market.

What to Do Now

1. Assess Your Current Environment: Identify all devices running Windows 10 Enterprise LTSC 2021 and evaluate their importance to your business operations. This includes understanding the specific roles these devices play and the potential impact of their downtime.
2. Plan for Transition: Develop a timeline for upgrading or replacing these devices before the end of support in 2027. Consider factors like budget, staff availability, and business continuity. For example, you might plan to upgrade critical systems first and then move on to less critical devices.
3. Consider ESU: Evaluate the cost and benefits of purchasing Extended Security Updates for the year following the end of support. ESU will cost $61 USD per device for the first year, with a ~25% discount available for early purchase ^[1]. This means you can purchase ESU for $45 USD per device if you act early.
4. Explore Alternatives: Research and compare other operating systems and versions that meet your business needs and are supported by Microsoft. For instance, you might consider upgrading to Windows 11, which offers enhanced security features and better compatibility with modern applications.
5. Consult with Experts: Engage with IT professionals to discuss the best approach for your specific situation. Total Group can provide tailored advice and support for your transition. We can help you assess your current environment, develop a transition plan, and manage the upgrade process.
6. Implement a Backup Plan: Ensure you have a robust backup and recovery strategy in place to protect against data loss during the transition period. This includes regular data backups and testing your recovery procedures to ensure they work as expected.
7. Train Your Staff: Provide training for your team on the new operating system or any changes in IT processes to ensure a smooth transition. This might include training sessions on new features, security best practices, and troubleshooting techniques.
