The definitive end of support for Windows 10 represents a major milestone that has a direct impact on the security, continuity and future development of corporate IT infrastructure. As of 14 October 2025, security updates, bug fixes and technical support for this system are no longer available. Although devices will remain functional, they are no longer protected – so any new vulnerability remains open without the possibility of remediation.
At the same time, any outage, incompatibility or cyber incident can be significantly more costly than upgrading the system itself. Audit checks can highlight the substandard state of the IT environment and increase the pressure for an immediate solution.
Increased risk of cyber attacks and incidents
An un-updated operating system is an ideal target for ransomware, phishing or data leakage attacks. For companies working with sensitive information, subject to GDPR or other regulations, this poses a significant compliance risk. Potential incidents caused by an outdated system can lead to financial losses, reputational damage or insurance claim complications.
What will it look like? Gradually, compatibility problems will start to show up. Software developers will stop testing new versions of their apps on Windows 10, and hardware manufacturers won’t provide up-to-date drivers either. This can cause disruptions in the use of specialist applications, accounting systems or peripherals on which the day-to-day running of the business depends. Microsoft also warns that Microsoft 365 apps on Windows 10 may perform less reliably over time, which can affect the productivity and stability of office processes.
This also entails an increased risk of financial and operational losses. If an incident is caused by a legacy operating system, it can be more costly and time-consuming to resolve. Audit checks can highlight the poor state of the IT infrastructure, increasing the pressure to upgrade. Downtime caused by software incompatibilities or outages can affect customer confidence and the overall reputation of the business. Additionally, in the event of a data leak, there is the threat of penalties and insurance claim complications if it is proven that the company was using an unsupported system.
The best available solution options
Before making a decision, it is recommended to inventory existing equipment, analyze compatibility with Windows 11, and create a realistic infrastructure upgrade plan.
- Switching to Windows 11 – the easiest and safest way.
A free upgrade is available for most compatible devices, bringing a more modern system, long-term support, and a significantly higher level of protection. (Applies to Windows 10 version 22H2 compatible devices.) - Buying new devices with Windows 11
If your hardware doesn’t support the upgrade, the most cost-effective solution is to buy a new device with Windows 11 pre-installed.You’ll not only get a higher level of security, but you’ll also get better performance and stability. - Extended Security Updates (ESU)
For businesses that need to stay on Windows 10 for a variety of reasons, Microsoft has created the Extended Security Updates program. It will allow you to get security patches for three years after support ends – until 2028. We can easily provide you with both ESU and Microsoft 365 licenses.
For businesses that need to stay on Windows 10 in the short term, it’s essential to significantly strengthen security measures, such as limiting device access to the internet, implementing advanced endpoint protection, isolating sensitive parts of the network, and consistently backing up data. Again, these are only temporary solutions that do not reduce the risk to zero.
