For information about what End Of Support (EOS) means, see our blog what does end of support mean.
For many businesses, Microsoft desktop products such as Microsoft Windows, Microsoft Office applications (Word, Excel, Outlook etc) and browsers such as Internet Explorer or Edge are among the main ways in which staff interact with and process business information.
When these products reach their end of support (EOS) date, they represent an increasing level of risk for your business unless you upgrade to a supported version of the product.
For desktop products, running EOS software makes your business particularly vulnerable to the most common types of cyber attack including:
- Phishing and Ransomware attacks – which are often perpetrated through using specially crafted Word, Excel or PDF attachments which contain malicious macros or code.
- Drive-by malware attacks which rely on out of date or insecure web browsers
You also risk difficulties in accessing modern cloud and server systems which rely on modern security features to keep your data secure. This will cause interruption of IT services for your staff, and possible loss of revenue if they are unable to work.
Microsoft Lifecycle Policy
Microsoft has a highly structured product lifecycle policy which helps customers understand and predict exactly when the products they are using in their business are going to reach their end of support date.
- Microsoft Windows 10 – Modern Policy
- Microsoft Windows (older versions) – Fixed Policy
