Still on Windows 10? Here’s What Happens After October 14

Microsoft is pulling the plug on Windows 10 support on 14 October 2025. That means no more security patches, bug fixes, or tech support. If your organisation is still running Windows 10 past that date, you're not just behind - you're exposed.

This isn’t fear mongering. It’s risk management. Cybercriminals are already circling this date on their calendars. The minute vulnerabilities go unpatched, exploits are fair game - and there won’t be a safety net.

Unsupported systems are magnets for attacks. With no future updates, Windows 10 will become:

• A backdoor to your network - through unpatched software flaws

• A compliance liability - especially under frameworks like ISO 27001 or NIST

• A ransomware target - older systems are prime bait

Even if your business uses firewalls, antivirus, or external protections, an outdated OS is the weakest link. And attackers only need one crack.

Cyber insurance providers are becoming far more stringent. Running unsupported software can void policies or limit payouts.

Think of it this way: if you left your business unlocked at night, would you expect insurance to pay out after a break-in? The same logic applies here.

If you're in healthcare, finance, legal, or any regulated industry, the risks compound. Auditors won’t just flag unsupported systems - they may escalate findings to a critical level, jeopardising certifications or client contracts.

Even if you're not in a regulated space, more clients are asking for proof of cybersecurity posture. Windows 10 after October? That’s a red flag.

It's not just about security. Old OS versions lead to:

• App compatibility issues - New software simply won’t support it

• Vendor lockout - Hardware and third-party services may drop support

• Productivity drops - When things start to break, support becomes DIY

And if something does go wrong? Your IT provider won’t be able to escalate to Microsoft. That’s a long - and potentially costly - troubleshooting rabbit hole.

1. Upgrade existing hardware to Windows 11

If your devices are compatible, this is the fastest path. Optimus can run upgrade assessments across your fleet to determine:

• Compatibility
• Cost
• Timelines
• Risk profile
  
  

We’ll also ensure a staged rollout that keeps productivity humming.

2. Replace machines that don’t meet Windows 11 specs

Some older hardware won’t make the cut - and we can't do anything about that. If your machines are five years old or more, this is your moment to modernise.

Replacing hardware doesn’t just solve the OS issue - it boosts performance, reduces support tickets, and improves staff satisfaction. It's a short-term cost for long-term gain.

Delaying means supply chain crunches, rising prices, and rushed decision-making. Plus, your IT team (or provider) will be stretched thin as more businesses scramble last-minute.

There’s no benefit to procrastination here - just increased risk and future cost.

We get it. Tech upgrades feel like disruption, especially when the business is busy. But doing nothing is no longer a neutral option.

The security threats are real. The compliance implications are serious. And the costs of inaction are already building.

Optimus is here to make the move simple, secure, and stress-free. Whether it's a fleet-wide upgrade, a targeted replacement plan, or both — we’ll guide the process from audit to implementation.

You don’t need to scramble in October. You just need to start in August.
