How to secure Windows 7 on your business devices

Running Windows 7 securely in 2025 is really challenging, and we don’t recommend it unless you absolutely have to.

How to use Windows 7 securely

Although Syn-Star always recommends using the latest version of all software, there are some cases when, for whatever reason, you must stick with an older version like Windows 7. Manufacturing, for example, is such an industry.  

Microsoft ended support for Windows 7 in January 2020 which means that you are no longer able to receive security updates.  So, if you still must use Windows 7 here are our recommendations to keep your systems as safe as possible.  

The Only Way to Use Windows 7 Securely: Offline and Unconnected

If you are forced to use Windows 7 for various reasons, it’s crucial to understand that the only way to use it securely is to keep it completely offline and unconnected to the network.

Using this approach ensures that your systems are protected from online threats such as malware, viruses, and cybercriminals.

Here’s why this is necessary and why you should always entrust an IT professional to handle this for you:

Why Keeping Windows 7 Offline is a Must!

  • Security Vulnerabilities: Since support for Windows 7 stopped in 2014, this has caused the system to become highly vulnerable to cyber threats. Keeping it offline prevents exposure to these online risks.

  • No Security Patches: Without the latest security patches to your Windows 7 systems, your out at a greater risk of data breaches along with other cyber attacks.

  • Outdated Software and Hardware Compatibility: New software and hardware are often incompatible with Windows XP, this increases your risk of security issues and downtime to your business.

  • Ineffective Firewall: The built-in firewall in Windows 7 is outdated and less effective compared to modern firewalls, making network-connected Windows 7 systems easy targets for exploitation.

The Role of IT Professionals

  • Expertise and Knowledge: Syn-Stars IT professionals have the expertise to properly isolate and secure your Windows 7 machines while ensuring compliance with cyber insurance and Cyber Essentials accreditation requirements. We help you stay protected and fully compliant year after year. 
  • Tailored Security Solutions: We regularly implement tailored security solutions which align with your specific business needs and regulatory requirements. Our customised approach will ensure your systems remain protected while meeting all necessary compliance standards. 
  • Disaster Recovery Plans: Syn-Star’s IT experts develop and maintain comprehensive disaster recovery plans for our clients to safeguard all data and systems. In the event of a cyber incident or system failure, we ensure you have a reliable plan in place to minimise downtime and recover quickly. 

What are the risks if your Windows 7 devices are connected to the internet?

Security Vulnerabilities: Since Microsoft ended support for Windows 7 in 2017, this system no longer receives security updates, leaving it highly vulnerable to modern cyber threats. Hackers are continuously developing new malware, ransomware, and viruses that can easily exploit outdated systems like Windows 7.

 

Lack of Modern Software Support: Most modern web browsers, such as Google Chrome and Mozilla Firefox, no longer support Windows 7. This means users are stuck with outdated browsers that lack security patches, increasing the risk of phishing attacks and malicious websites.

Additionally, many essential software programmes, including antivirus applications, no longer function properly on Windows 7, leaving users even more exposed to cyber threats. 

 

Unsecured Network Risks: Even if you are only using Windows 7  within a local network, this can still be a weak point for attackers. If an infected device connects to the same network, malware can spread to Windows 7 systems due to their outdated security protocols. 

 

Mitigating Risks: If you are currently using Windows 7, the best way to minimise risks is to keep it completely offline. 

If you’re unsure how to secure your Windows 7 system or need assistance with safer alternatives, contact us for expert guidance and tailored solutions. We’re here to help ensure your systems remain as secure as possible. 

 

Example: The ryuk Ransomware attack in 2017 this ransomware spread to more than 200,000 computers in over 150 countries. Companies affected included: FedEx, Honda, Nissan, and the UK’s National Health Service (NHS).

This ransomware attack operates on system vulnerabilities being able to jump from computer to computer, installing copies of itself causing widespread damage. Without security updates, Windows 7 lacks protection against such threats, making it unsafe for internet use. 

Can You Still Get Cyber Essentials Plus Accredited When Using Windows 7?

No, within the normal circumstances, you cannot get Cyber Essentials Plus accreditation if you are using Windows XP.

To achieve Cyber Essentials certification, all devices within the scope of your assessment must have operating systems that are supported by the manufacturer.

Since Windows 7 has reached end of life and is no longer supported by Microsoft, it does not meet the requirements for Cyber Essentials certification.

However by choosing to partner with Syn-Star, a trusted IT provider for manufacturing businesses across the UK, we have tackled this dilemma many times putting in place strict measures to ensure your business can achieve cyber essentials while containing operations on operating systems like Windows 7.

Will Using Windows XP Affect My Ability to Get Cyber Insurance?

Yes, using Windows 7 can affect your ability to get cyber insurance or it can massively increase your risk profile and increase your payment amount.

Insurance providers often require businesses to use supported and up-to-date operating systems to minimise the risk of cyber threats.

Since Windows 7 is no longer supported and does not receive security updates, it is highly vulnerable to cyber-attacks.

This increased risk can make it difficult to obtain cyber insurance or result in higher premiums. For support tackling this issue please get in touch.

Syn-Star understands that you might not have a choice whether you update your Windows 7 operating system or not. So, if you need any help with running Windows 7 or potentially upgrading to newer machines, then Syn-Star can help.
