What companies need to consider in the IT sector in 2025

Future-proof IT: what companies need to be aware of in 2025

The year 2025 will bring significant changes to the IT landscape that will play a key role for companies. In addition to the discontinuation of popular operating systems such as Windows 10, important server operating systems and Office apps will also no longer be supported. Companies that ignore these issues expose themselves to a high level of risk – from security gaps to increased IT costs due to short-term emergency solutions. However, with timely planning, you can not only minimize risks, but also make your IT future-proof and efficient.

In this article, we highlight the most important topics and give you specific recommendations on how you can adapt your IT strategy for 2025.

End of support for Windows 10 in October 2025

Microsoft is ending support for Windows 10 – a milestone that affects many companies. Without security updates, there are massive risks for your IT infrastructure, including attacks by cyber criminals and compliance issues.

What to do?

• Upgrade planning: Switch to Windows 11 to continue benefiting from new features and security updates.

• Check hardware compatibility: Make sure that your devices are suitable for Windows 11. For older PCs, it is worth considering a replacement.

• Carry out test runs: First install Windows 11 on a few test devices before rolling it out across the board.

Terminal server and Office 365: a crucial combination

From October 2025, support for Office apps on Windows Server 2016 and 2019 will end. This will particularly affect companies that use terminal servers, as this environment will no longer be compatible with the latest Office applications. This change requires a migration to more modern operating systems such as Windows Server 2025 to ensure functionality and avoid security risks.

Recommended steps:

1. Check licensing model: Make sure that your current Office licenses can also be used in virtual environments.

2. Performance optimization: Check whether your terminal servers meet the requirements of modern office apps.

3. Migration to Windows Server 2025: Plan the changeover early to minimize interruptions to operations.

Operating systems 2016 and 2019: Support expiring

Support for Windows Server 2016 has already expired – it’s high time to replace this operating system. Windows Server 2019 will also cease regular support in October 2025. The longer you wait to make the change, the more intensive the transition will be – not only for your budget, but also for your staff.

Options for action:

• Upgrade to Windows Server 2025: Switch to the latest version to ensure full compatibility with Office apps and up-to-date security standards.

• Cloud-first strategy: Check whether switching to a cloud solution such as Azure can relieve and modernize your IT.

• Consider Extended Support: For companies that need more time, Microsoft offers Extended Support for a fee.

Practical implementation: What companies should do now

The biggest danger is putting the issue off. Here are some tips on how you can be proactive:

1. IT inventory: Which systems and applications are affected? Create a list.

2. Define your strategy: Do you want to stay on-premise, move to the cloud or use a hybrid solution?

3. Create a schedule: Set milestones for the changeover to avoid getting caught up in time pressure.

4. Involve experts: IT service providers such as Leftclick AG help you to find and implement customized solutions.

Why act now?

Many companies tend to delay IT changes for as long as possible. But this can be costly – whether due to security gaps, inefficient systems or unexpected downtime. The good news is that with the right planning and a competent partner at your side, you can not only master the changeover with ease, but also use it as an opportunity to future-proof your IT.
