Microsoft’s support for Windows 10 ends on 14 October 2025, and as of this week, that’s just a little over 100 days away. After that, devices still running Windows 10 will no longer receive security updates or official support.
If your business hasn’t made the switch yet, now is the time to act. The risk of delay is no longer theoretical; it’s a timeline that’s quickly approaching.
Why Waiting Until September Isn’t a Safe Plan
As we get closer to the deadline, IT providers like Coltek I.T. will be fielding urgent requests from businesses that didn’t act in time. By then, options may be limited, hardware may be harder to source, and upgrades could be more disruptive.
Doing it early means:
-
Less downtime
-
Lower risk of compatibility issues
-
Better control of cost and hardware selection
-
More time for staff to adjust to the new system
Unsupported Software Means Increased Cyber Risk
When support ends, Microsoft will stop issuing critical security updates for Windows 10. That makes systems running it far more vulnerable to malware, ransomware, and unauthorised access.
If your business handles NDIS data, healthcare records, financial information or customer files, running an unsupported operating system is a risk you cannot afford.
Even if everything “seems fine” now, cybercriminals often target unpatched systems. Without updates, those devices become easy entry points.
Can Your Devices Run Windows 11?
Not all devices currently running Windows 10 will be compatible with Windows 11. The minimum hardware requirements include Secure Boot, TPM 2.0, and specific CPU models. If your fleet includes devices older than 4–5 years, they may not be eligible for the upgrade.
Coltek I.T. can help you determine which machines can be upgraded, which should be replaced, and how to spread the cost across a staged rollout.
What You Can Do This Month
If you haven’t started your Windows 10 transition yet, June is your time to take action. Start with a full system audit and begin building your rollout plan.
