Microsoft has officially announced the Windows 10 end of life date: October 14, 2025. While that might seem like a distant deadline, the time to act is now—especially since Windows 10 still powers roughly 65% of computers worldwide.
Once support ends, Microsoft will no longer provide security updates, bug fixes, or technical support. That means businesses relying on it will be exposed to significant security vulnerabilities and operational risks.
What Happens After Support Ends?
After the October 14, 2025, deadline, Windows 10 devices will no longer receive:
- Security patches
- System updates
- Technical support from Microsoft
This opens the door to serious risks across security, operations, and compliance.

Key Risks for Businesses
Security Vulnerabilities
- Systems become prime targets for cyberattacks
- Increased risk of ransomware, malware, and phishing
- Greater likelihood of data breaches
Operational Disruptions
- Software incompatibility and crashes
- Unexpected downtime
- Lower productivity and user frustration
Compliance and Legal Consequences
- Non-compliance with industry regulations
- Potential fines and legal issues
- Reputational damage
Your Business Action Plan
1. Assess Immediately
- Inventory all devices running Windows 10
- Use the Microsoft PC Health Check tool
- Identify hardware that can be upgraded vs. what needs to be replaced
2. Strategize Your Upgrade Path
- Create a phased rollout plan
- Prioritize mission-critical systems
- Plan your budget and upgrade timeline
- Schedule employee training early
3. Prepare Technically
- Backup all data (preferably with redundancy)
- Test and ensure cloud storage availability
- Verify application compatibility with Windows 11
- Conduct pilot testing on a small group of users
What About Extended Support?
Microsoft does offer Extended Security Updates (ESUs) for businesses that need more time—but at a steep cost:
- Year 1: $50+ per device
- Year 3: $200+ per device
- Limited security-only coverage
- No support for hardware or drivers
This should be a temporary measure only, not a replacement for a full upgrade strategy.
Suggested Timeline
| Timeframe | Key Actions |
| Now | Assess systems, build your budget, consult with IT provider |
| Early 2025 | Begin phased upgrades, implement data backups, train users |

Why Acting Early Pays Off
- Avoid the last-minute scramble
- Reduce exposure to cyber threats
- Keep systems running smoothly
