Introduction
Our previous blogs have taken an in-depth look at the migration to Windows 11, and the withdrawal of support for Windows 10 as of Tuesday 14th October 2025.
With the clock relentlessly marching towards that date, this latest article explains the Windows 10 security risks associated with delaying the switchover, and how unsupported operating systems can leave the door wide open to hackers.
Windows 11 is perhaps the most important software upgrade your business will make – it’s an investment in security and productivity, giving you peace of mind to focus on your core work.
Why hackers love unsupported systems
When it comes to Windows, you can think of Microsoft as the neighbourhood security patrol, checking that entrances are guarded and doors securely locked to keep the criminals at bay.
When support for Windows 10 ends, your security patrol are getting in their van and heading into the sunset. Their replacements are on the way – but only if you’re operating on the latest system.
This means that any vulnerabilities (broken windows or ill-fitting doors, to use our analogy) remain open. There will be no service to shore up defences, inviting hackers to pounce.
And hackers love unsupported software. It’s an open invitation for them to easily deploy malware and ransomware capable of having a devastating impact on any business or organisation.
Real-world impact of cyber attacks
Cyber threats don’t just mean a bit of disruption; they can mean serious damage.
If your customers’ data is breached, not only will trust in your organisation be affected, you may well have a PR disaster on your hands.
Aside from potentially handing over banking details of your clients, other sensitive information could also be leaked with real-world consequences.
A 2024 data breach occurred involving Alltech Consulting Services. The recruitment firm’s unsecured database handed over 216,000 jobseeker records, including sensitive personal information such as names, phone numbers, email addresses, passport numbers and work visa status.
This data was then available for criminals to use in identity theft, spear phishing and fake job scams, highlighting the real-world consequences of poor data security.
Aside from trust and PR problems, a cyber attack can lead to financial loss. Just this year the Co-operative Group suffered an attack that led to an estimated £206 million in lost sales revenue and an £80 million hit to earnings, despite insurance coverage.
There are then the long-term recovery costs of getting systems back up and running including IT forensics, malware removal and system rebuilds. Studies show average downtime costs £4,500 per minute, with recovery stretching into months.
Prevention is better than cure
It’s a cliché for a reason. We all know, deep down, that the cost of investment in secure systems far outweighs the risk of an attack that could close a business.
Windows 11 migration is about future-proofing your business, keeping those security guards on patrol 24/7 to make sure there are no holes in the defences.
Key security features include:
- Smart App Control to block untrusted or malicious apps
- Built-in VPN protocols for secure remote access for hybrid teams
- Advanced encryption and firewall protection
- Secure boot and hardware-based isolation to offer protection from rootkits and firmware attacks
- Regular updates and support to give ongoing protection from emerging threats
Migration to Windows 11
With the right preparation and support, migration to Windows 11 can be smooth and hassle-free.
Our previous blog looked at some of the key considerations. Here’s a quick recap:
- Are your systems able to cope with the requirements of Windows 11, or should you be moving to a cloud-based solution?
- Will those legacy apps you’re using still function properly via Windows 11?
- Do you need to train staff ready for the switchover?
- Do you need to invest in new hardware and are supplies readily available?
As the Windows 10 end of support deadline looms, and the security team load up their van, it’s time to make the change.
“Windows 10 end of life has been on the cards since mid-2022. Back then it felt like a lot of time to prepare for the change. It has come around quickly and many businesses have already made the switch, but there are a few that haven’t yet embraced the OS of the future.
“Our advice to those businesses is start now. There’s still time to make the switch, and there are options available from Microsoft should you need a little extra room to prepare. It’s important to be proactive and start the process as soon as possible to keep your business secure, productive and competitive.
