Windows 10 Support Has Ended. What Should Your Business Do Now?
If your business is still running Windows 10, you’re not alone. Many organizations continue to use it every day because, on the surface, everything appears to be working fine.
The problem is that Microsoft’s support for Windows 10 ended on October 14, 2025. While your computers still power on, run applications, and access the internet, they are no longer receiving the regular security updates that protect against newly discovered threats.
That means the longer a Windows 10 system remains in service, the more vulnerable it becomes.
For most businesses, the options are straightforward: upgrade to Windows 11, purchase Extended Security Updates to buy additional time, or replace aging hardware altogether.
Before deciding which path makes sense, it’s important to understand what “end of support” actually means.
What Does End of Support Mean?
When Microsoft ends support for an operating system, it stops releasing updates for that product.
For Windows 10, that means:
- No new security patches
- No bug fixes or quality updates
- No feature enhancements
- No Microsoft technical support
Your computer doesn’t suddenly stop working. In fact, that’s part of the challenge. Everything seems normal, making it easy to delay action.
Behind the scenes, however, newly discovered vulnerabilities remain unpatched. Security researchers and cybercriminals continue finding flaws, but Microsoft is no longer fixing them.
Every newly discovered weakness becomes a permanent risk to any Windows 10 computer that remains online.
Why This Matters to Your Business
Running Windows 10 today isn’t simply a matter of using older technology. It can create real business risks.
Increased Security Exposure
Cybercriminals actively look for systems running unsupported software because they know vulnerabilities will remain open indefinitely.
Once a flaw becomes publicly known, attackers can develop tools to exploit it with little fear that the target system will be protected by a future update.
Unsupported operating systems often become low hanging fruit for ransomware groups and other threat actors.
Potential Compliance Issues
Organizations subject to regulations such as:
- HIPAA
- PCI DSS
- Financial or privacy regulations
are generally expected to use supported and regularly patched software.
Continuing to operate unsupported systems may create compliance concerns and increase exposure during audits or investigations.
Cyber Insurance Challenges
Many cyber insurance providers now evaluate an organization’s security posture before issuing or renewing coverage.
Running unsupported operating systems can potentially result in:
- Higher premiums
- Coverage limitations
- Additional policy requirements
- Increased scrutiny during claims reviews
Software Compatibility Problems
Over time, software vendors stop supporting older operating systems.
Browsers, accounting applications, security tools, and line of business software may eventually stop receiving updates or become incompatible with Windows 10 altogether.
The result is increased operational risk and reduced reliability across your environment.
Your Three Options
Most organizations end up using a combination of these approaches depending on the age and role of each device.
1. Upgrade to Windows 11
For devices that meet Microsoft’s hardware requirements, upgrading to Windows 11 is usually the most cost effective solution.
Many business computers purchased within the last several years are capable of making the transition without replacing hardware.
Windows 11 requires:
- A supported processor
- TPM 2.0
- Secure Boot support
Microsoft’s PC Health Check tool can determine whether a specific device qualifies.
For eligible systems, upgrading provides continued support and ongoing security updates while preserving users’ files and applications.
2. Purchase Extended Security Updates (ESU)
If a device cannot be upgraded immediately, Microsoft’s Extended Security Updates program can provide temporary protection.
ESU allows eligible Windows 10 devices to continue receiving critical security updates for a limited period after end of support.
This option is designed as a bridge, not a permanent solution.
It can be useful for:
- Legacy applications
- Specialized equipment
- Budget planning cycles
- Systems awaiting replacement
However, Extended Security Updates only provide security fixes. They do not include new features, major improvements, or full product support.
3. Replace the Device
For older hardware, replacement is often the smartest long term investment.
If a computer cannot meet Windows 11 requirements, continuing to maintain it may become increasingly expensive and risky.
A modern Windows 11 device typically provides:
- Better performance
- Improved security features
- Longer support lifespan
- Lower maintenance costs
- Enhanced reliability
When comparing replacement costs against ongoing support fees and productivity losses, purchasing new hardware is frequently the more economical choice.
How to Plan Your Transition
The good news is that you don’t need to replace everything overnight.
A structured approach can make the process manageable and cost effective.
Step 1: Identify All Windows 10 Devices
Create an inventory of every workstation, laptop, and specialty device still running Windows 10.
Many businesses are surprised to discover just how many systems remain.
Step 2: Determine Upgrade Eligibility
Evaluate which devices meet Windows 11 hardware requirements.
A simple assessment can quickly separate upgrade candidates from replacement candidates.
Step 3: Upgrade Eligible Systems
Devices that qualify should generally be upgraded first.
This reduces risk immediately while minimizing costs.
Step 4: Review Remaining Devices
For systems that cannot upgrade:
- Determine whether they are business critical
- Evaluate replacement costs
- Consider Extended Security Updates if additional time is needed
Step 5: Establish a Timeline
The worst approach is having no plan at all.
Even if upgrades and replacements occur gradually, establishing a roadmap ensures unsupported devices don’t remain in service indefinitely.
Frequently Asked Questions
Is Windows 10 still usable after support ended?
Yes. Windows 10 computers continue to function normally. However, they no longer receive regular security updates, making them increasingly vulnerable over time.
What happens if I do nothing?
Your systems will continue operating, but security risks will grow as new vulnerabilities are discovered and left unpatched. You may also face compliance, insurance, and software compatibility challenges.
Can my computer upgrade to Windows 11 for free?
If the hardware meets Microsoft’s requirements, the upgrade is generally available at no additional licensing cost. Microsoft’s PC Health Check tool can verify eligibility.
Are Extended Security Updates a long term solution?
No. ESU is intended to provide temporary breathing room while organizations complete migration plans. It should be viewed as a bridge, not a destination.
Should I replace older computers?
If a device cannot run Windows 11 or is nearing the end of its useful life, replacement is often the best long term solution from both a security and financial perspective.
Final Thoughts
Windows 10’s end of support doesn’t mean your computers stop working. It means Microsoft has stopped protecting them.
Every month that passes increases the likelihood that unsupported devices become an entry point for cybercriminals. Whether your organization chooses to upgrade, purchase Extended Security Updates, or replace aging hardware, having a plan is far better than waiting for a problem to force one.
For most businesses, the safest and most cost effective path is clear: identify your remaining Windows 10 systems and begin moving toward Windows 11 before those unsupported devices become a security liability.
