Windows 10 could become a billion dollar burden for businesses that stay on it

Windows 10 support ends in 2025

Microsoft will officially end support for Windows 10 on October 14, 2025. Also, Microsoft 365 Apps on Windows 10 will lose support on that date; though they may continue to function, performance and reliability may degrade over time.

Businesses continuing to use Windows 10 will lose access to critical protections and may face higher exposure to cyber threats.

Understanding this timeline is essential for organizations of all sizes to plan system upgrades, maintain security, and avoid disruptions in day-to-day operations. Planning now can prevent costly issues later.

Extended Security Updates program

For organizations that cannot upgrade immediately, Microsoft offers an Extended Security Updates (ESU) program. This program delivers critical and important security patches for up to three years beyond the end of support.

For businesses, ESU is available through Volume Licensing and requires a separate agreement; for individual users, a consumer ESU option exists. While ESU can help businesses maintain security temporarily, it is not a permanent solution.

Companies should evaluate their long-term migration plans while using ESU to ensure they do not remain on unsupported systems longer than necessary.

Rising ESU costs

The ESU program carries yearly fees per device, which can become substantial for large organizations.

Specifically for organizations, the price doubles in each consecutive year under the three‑year ESU term. For consumers, only Year One is available at a fee of about $30 per device, for the period from October 15, 2025, to October 13, 2026.

Businesses must weigh these fees against the costs of upgrading devices and migrating to a supported operating system. Proper budgeting and early planning are critical to avoid paying both ESU fees and future hardware or software expenses simultaneously.

Security risks increase

After support ends, Windows 10 systems will no longer receive updates, leaving them vulnerable to malware, ransomware, and other cyber threats. Unsupported devices are often targeted first by hackers because they lack protections against newly discovered vulnerabilities.

Organizations that continue to operate on Windows 10 may experience breaches, downtime, or data loss. These risks can be far more costly than upgrading or participating in the ESU program.

Ensuring systems are protected with supported software is critical to maintaining business continuity and avoiding potential financial and reputational damage.

Compliance issues for businesses

Many industries are required to use supported software to meet regulatory standards. Continuing to operate Windows 10 past its end-of-support date may lead to compliance violations. This can result in fines, legal consequences, or audit failures.

Sectors such as healthcare, finance, and government are particularly affected because outdated systems may not satisfy data protection requirements. Organizations must evaluate their regulatory obligations and implement timely upgrades or ESU coverage to maintain compliance and protect sensitive data from vulnerabilities.

Hardware requirements for upgrades

Windows 11 requires devices to meet specific hardware standards, including a 1 GHz dual-core processor, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot, and TPM version 2.0.

Older machines that do not meet these requirements cannot be upgraded and may need replacement. Businesses must inventory current devices to determine compatibility and plan purchases accordingly.

Proper evaluation ensures that upgrades are completed efficiently without disrupting workflows or exceeding budgets. Failing to meet requirements could force companies into costly temporary solutions.

Migration options for companies

Businesses can either upgrade existing compatible devices to Windows 11 or replace older hardware entirely. Upgrading preserves current investments, while replacing machines ensures compatibility and access to modern security features. Some organizations may also explore alternative operating systems depending on operational needs.

Each option carries financial and logistical considerations, and companies must balance cost, downtime, and workforce training to ensure a smooth transition without compromising productivity. Careful planning minimizes risks and ensures all systems remain secure and compliant.

Planning a successful migration

To transition effectively, companies should conduct a full device inventory and assess which machines can support Windows 11.

Developing a clear timeline for upgrades or replacements allows IT teams to manage resources efficiently. Budgeting for software, hardware, and employee training is essential to avoid unexpected costs.

Testing critical applications and workflows before full deployment ensures compatibility and reduces disruptions. A structured migration plan allows businesses to move from Windows 10 on schedule, minimize security risks, and maintain operational continuity.

Training and support needs

Employees will need guidance to adjust to Windows 11’s interface and features. Providing comprehensive training materials, workshops, and helpdesk support helps reduce frustration and errors.

Clear communication about changes, expectations, and timelines ensures that staff can adapt quickly. Proper training also prevents workflow disruptions and maximizes the benefits of new features. Organizations that invest in employee support during upgrades are more likely to complete migrations smoothly and maintain productivity.

IT infrastructure updates

Migrating from Windows 10 may require updates to the IT infrastructure. Network configurations, security protocols, and software applications must all be compatible with Windows 11.

Ensuring that infrastructure can support the new operating system reduces potential technical issues and downtime. Updating IT systems also provides an opportunity to strengthen cybersecurity, improve network efficiency, and optimize device management.

Aligning infrastructure upgrades with the migration plan ensures a smoother transition and minimizes disruptions to employees and operations, while also allowing IT teams to implement modern tools and practices that support future technology needs.

Third-party software considerations

Some third-party software vendors will eventually discontinue support for applications running on Windows 10. Organizations relying on these programs must confirm compatibility with Windows 11 to avoid disruptions.

Failure to verify could lead to operational issues, productivity loss, or unexpected expenses. Early coordination with software providers allows businesses to plan necessary updates, find alternatives, or ensure licenses are compatible.

By addressing third-party dependencies before migration, companies can prevent workflow interruptions, reduce risks of downtime, and ensure critical applications remain fully functional throughout and after the upgrade process.

Data backup and recovery planning

Before initiating a migration, businesses should implement comprehensive data backup and recovery plans. Backing up files, system settings, and applications ensures that no critical data is lost during upgrades or hardware replacements.

A well-structured recovery plan also provides protection against unexpected failures, ransomware attacks, or technical issues that may occur during the transition.

Organizations that prioritize data safety reduce risk, maintain business continuity, and can restore operations quickly if problems arise. Establishing robust backup protocols is a critical step in any operating system migration strategy.

Communicating with stakeholders

Effective communication with employees, management, and clients is essential during the migration process. Informing stakeholders about timelines, expectations, and available support resources prevents confusion and minimizes disruptions.

Clear guidance ensures that staff understand new procedures, helps maintain productivity, and fosters cooperation throughout the transition. Regular updates on progress and issues encourage transparency and allow stakeholders to adjust planning as needed.

Organizations that prioritize communication are more likely to execute a smooth migration and sustain operational stability during system upgrades.

What to do after Windows 11 upgrade?

After completing the migration to Windows 11, organizations should actively monitor systems for performance issues, errors, or application incompatibilities.

Providing ongoing support helps resolve problems quickly and prevents extended downtime. Continuous monitoring also identifies areas where additional training or adjustments may be necessary.

IT teams can track system stability, ensure software functionality, and maintain security compliance. By investing in post-migration oversight, businesses safeguard their operations, maximize the benefits of upgraded systems, and minimize risks associated with transitioning from Windows 10.

Evaluating long-term IT strategy

The end of support for Windows 10 offers businesses a chance to evaluate long-term IT strategies. Organizations can consider cloud adoption, enhanced cybersecurity measures, and integration of modern tools during the migration.

Aligning system upgrades with broader technology goals ensures sustainability, efficiency, and preparedness for future software updates.

Companies that strategically plan hardware and software investments can reduce costs, improve productivity, and avoid repeating migration cycles unnecessarily. This approach allows IT teams to optimize infrastructure and maintain secure, reliable, and modern systems for the foreseeable future.

To keep your system secure and running smoothly for a long time, start by protecting your PC by adjusting these key Windows options.

Prepare early for Windows 10 transition

To mitigate risks associated with the end of Windows 10 support, businesses should act promptly. Planning early, allocating resources, and consulting IT experts ensures a smooth transition.

Migrating before the end-of-support date provides long-term access to security updates, modern features, and vendor support. Companies that schedule upgrades carefully avoid emergency ESU payments, maintain regulatory compliance, and minimize productivity loss.
