Windows 10 EndofSupport (Oct 2025): 45Day Action Plan

What Does Windows End of Support Mean?

Devices will continue to run, but without security updates they face higher risk from malware, ransomware, and compliance issues. Per Microsoft’s lifecycle policy, organisations should migrate to a supported OS (e.g., Windows 11) to remain protected.

Why You Need to Act Now

• Security risks: Unpatched vulnerabilities can lead to cyberattacks.
• Compliance issues: Outdated systems may fail security audits.
• Productivity losses: Unsupported apps and crashes can impact operations.
• Limited vendor support: Many third-party apps will phase out Windows 10 compatibility.

Your 45-Day Action Plan

Days 1–15: Assessment & Planning

• Audit all devices still running Windows 10.
• Identify critical systems and dependencies.
• Check hardware compatibility with Windows 11 (use Microsoft’s PC Health Check tool).
• Estimate budget and resources for upgrades.

Days 16–30: Pilot Migration

• Select a small group of users or non-critical systems.
• Test hardware, drivers, and application compatibility.
• Trial backup and recovery solutions.
• Train IT staff on new Windows 11 features and security controls.

Days 31–45: Full Rollout

• Execute a phased migration across departments.
• Update security policies and endpoint protection.
• Communicate changes to staff and provide quick reference guides.
• Retire unsupported devices or consider virtualisation for legacy apps.

Options If You Can’t Migrate Immediately

If migration is delayed, consider these interim measures:

• Purchase Windows 10 Extended Security Updates (ESU) from Microsoft.
• Use virtual desktop infrastructure (VDI) to isolate outdated systems.
• Prioritise upgrades for systems handling sensitive data.
