Windows 10 Update Information – Significant for your Cyber Essentials compliance 

Jul 11, 2023 | Cyber Essentials

Cyber Essentials certification requires organisations to use software that is licensed and supported. As some versions of the Windows 10 Operating System will soon become unsupported by Microsoft, this is significant for those organisations that use Windows 10 and are seeking to certify or re-certify to Cyber Essentials.  


What is meant by updates? 

All software needs regular security updates to patch errors or ‘vulnerabilities’ in the code which criminals can exploit. If software is not receiving these updates, it becomes ‘unsupported’ and is vulnerable to threats. It will also fall out of compliance with Cyber Essentials. 

When software gets to a certain age, the vendor ceases to create and send out patches or security updates. At this point, the software is classed as ‘legacy’ or ‘end of life’ as it is no longer supported and therefore no longer secure to use. 

Not only are software vulnerabilities left un-patched, but they become common knowledge for hackers who create programs and services to make them easy to exploit, even for criminals with low levels of technical expertise. 

Microsoft Windows 10 is the most widely used Windows Operating System (OS). There are four editions of Microsoft 10 – Home, Professional, Enterprise and Education. 

Microsoft has announced that from June 2023, Windows 10 machines running the Home and Professional editions will only receive security updates if they are running the latest version of the OS (known as 22H2), this will potentially leave some machines unsupported and non-compliant for Cyber Essentials. 

Microsoft have also published dates for the Enterprise and Education editions in 2024 from which only the latest version 22H2 will receive security updates. 

We have created the table below to illustrate the dates that affect the different versions. The timetable shows the dates that are relevant for Cyber Essentials.
