Is your organization ready for the end of Windows 10 support?

The end-of-support deadline for Windows 10, set for October 14, 2025, is inexorably approaching. For IT decision-makers - and project managers, this is a signal for immediate action. Leaving systems without vendor support is not only a technology risk, but a strategic threat to the business continuity and security of the entire organization. Ignoring this date can lead to serious consequences, including vulnerability to advanced zero-day attacks, the growing threat of malware and ransomware that can exploit gaps that have already gone unpatched.

Keep in mind that a lack of security updates also means potential compliance issues with regulations such as RODO, FSA guidelines and the NIS2 directive, which can result in severe financial and reputational penalties. Moreover, outdated operating systems may soon become incompatible with new versions of key business applications, negatively affecting productivity and operational efficiency. Therefore, migrating to Windows 11 should not just be seen as a necessary upgrade, but as a strategic investment in maintaining a “digital edge” and ensuring a stable, secure IT environment.

A proactive approach and careful planning of the transition process are key. This includes not only technical aspects, but also communication within the organization and preparing users for the coming changes. Working with an experienced digital transformation partner can significantly ease the process, minimizing risk and maximizing the benefits of the new platform. Now is the time to verify readiness, assess resources and take decisive steps toward modernization.

How to check if your hardware is compatible with Windows 11?

The first, fundamental step in the Windows 11 migration planning process is a detailed inventory and assessment of existing computer hardware. Organizations must accurately identify which current workstations and laptops meet the minimum system requirements of Windows 11. The key components to verify are first and foremost a processor (the appropriate generation is required, typically 8th generation Intel Core or AMD Ryzen 2000 and later), at least 4 GB of RAM (although 8 GB or more is recommended for comfortable operation), 64 GB of free disk space, and a graphics card compatible with DirectX 12 or later with the WDDM 2.0 driver. Support for UEFI with Secure Boot is also essential.

To make the process easier, you can use Microsoft’s “PC Health Check” tool, which automatically analyzes the configuration of a given device. For larger organizations, IT professionals can use scripts or infrastructure management tools (UEM/RMM) for mass compatibility verification. The results of this analysis will have a direct impact on budgeting and planning for potential new equipment purchases. CTOs and CIOs need to factor these costs into their modernization strategies by analyzing the total cost of ownership (TCO) of new equipment versus the risks and constraints of maintaining older, incompatible equipment.

For devices that do not meet Windows 11 requirements, strategic decisions need to be made. The main option is to replace the hardware with a new one, which guarantees full compatibility and access to all the features of the new system. Alternatively, for less critical applications or to optimize costs, you can consider installing Linux-based operating systems on older computers. Such a solution can extend the life of the hardware and provide security for specific tasks, but comes with the potential need to train users and ensure compatibility with the required software. A professional assessment of your IT infrastructure, conducted by experienced consultants, can help you choose the optimal path.

Why is the TPM 2.0 module crucial for Windows 11?

The Trusted Platform Module (TPM) version 2.0 is one of the key hardware requirements for Windows 11 and plays a crucial role in enhancing the platform’s security. It is a specialized microchip (or firmware implemented in the processor) that provides advanced hardware-based security features. Its main task is to protect cryptographic data, such as encryption keys, digital certificates and passwords, from malware and unauthorized access. With TPM 2.0, Windows 11 can perform functions such as Secure Boot, which prevents unauthorized operating systems and bootkits from loading.

In addition, TPM 2.0 is essential to take full advantage of disk encryption technologies such as BitLocker. By storing encryption keys in a secure, isolated hardware environment, TPM makes it significantly more difficult for them to be taken over, even if the hard drive is physically stolen. The module also supports identity authentication features, including Windows Hello, which allows users to log in using biometrics (e.g., facial recognition, fingerprint) more securely than traditional passwords. From a CSO’s perspective, the implementation of TPM 2.0 is an important part of building a multi-layered cybersecurity strategy.

Although unofficial methods of installing Windows 11 on computers not equipped with an active TPM 2.0 module can be found online, this approach is strongly discouraged in corporate environments. Skipping this requirement not only exposes the system to greater security risks, but can also lead to compatibility issues, lack of access to future feature updates and even denial of technical support from Microsoft. For organizations that value professionalism and strive for operational excellence, ensuring compliance with official vendor requirements, including having TPM 2.0, is fundamental to the stable and secure operation of Windows 11.

How to secure data before migrating to Windows 11?

Data protection is an absolute priority before proceeding with any operating system migration activities. No matter how carefully the transition to Windows 11 is planned, there is always the risk of unforeseen problems that could lead to the loss of valuable company information. That’s why the first and most important step is to take complete, verified backups of all critical data residing on the migrated workstations. This includes user documents, project files, application configurations and any other data necessary for business continuity.

Proven backup strategies such as the 3-2-1 rule (three copies of data, on two different media, with one copy stored in a different location) are recommended. Both full backups and incremental or differential backups should be considered, depending on the specifics of the data and available resources. It is crucial not only to perform the backup itself, but also to verify it through a trial restore. Only a tested backup will give you the confidence to quickly and effectively restore lost information in the event of a disaster. It’s also worth implementing a data classification process to identify and prioritize those most important to your business.

In preparation for the migration, it is also worth considering tools and techniques to ensure data integrity during the transfer process itself, such as using checksums to verify the accuracy of copied files. For organizations that manage large amounts of sensitive data, working with IT security experts can help develop and implement a robust data protection strategy to minimize risk throughout the migration project. Remember that proactive data security is the foundation for the success of any technology transition.

Why run targeted Windows 11 tests?

Before deciding on a mass deployment of Windows 11 across an organization, it is crucial to conduct carefully planned testing on a limited, representative group of users and devices. This approach, often referred to as pilot deployment or User Acceptance Testing (UAT), allows for early identification and resolution of potential problems before they affect the company wide. These tests should include not only verification of basic system functionality, but also verification of compatibility with key business applications, specific hardware configurations and integration with existing network infrastructure and security systems.

The pilot group should consist of users representing various departments and roles in the organization, including IT specialists, technical team leaders and representatives of key business departments. Their task will be to work on the new system on a daily basis and to actively report any difficulties, errors or performance problems encountered. The feedback gathered in this way is an invaluable source of knowledge that allows refining the system configuration, preparing appropriate training materials and improving the implementation process itself. For project managers, such tests significantly reduce the risk of project failure and increase acceptance of the new system among employees.

It’s also worth considering testing in a dedicated virtual environment, which allows you to quickly test different scenarios and configurations without affecting production user systems. For example, during testing you may find that a specific legacy application used by the finance department does not work properly under Windows 11. Detecting this problem at the pilot stage gives you time to find a solution - such as updating the application, looking for an alternative or using virtualization - before the problem affects all users of that application. Meticulous testing is an investment that pays off with a smoother and more efficient implementation.

What to do with third-party software before migration?

A key part of preparing for a Windows 11 migration is to carefully analyze and manage the portfolio of applications used in the organization, especially those provided by third parties. Many of these applications, especially older versions, may not be fully compatible with the new operating system, which can lead to errors, instability or a complete inability to run them. Therefore, it is essential to conduct a detailed inventory of all software and verify its compatibility with Windows 11.

This process should start with a complete list of all applications used in the company, including their versions and the departments that use them. Then, for each application, check its manufacturer’s official position on Windows 11 support. This information can usually be found on vendor websites or in technical documentation. Particular attention should be paid to business-critical applications - their incompatibility could mean serious disruptions to operations.

If incompatible applications are identified, it is necessary to take appropriate action. The best solution is to update the software to the latest version that is officially supported on Windows 11. If an update is not possible or does not solve the problem, consider looking for alternatives that offer similar functionality and are compatible with the new system. In some cases, you can use compatibility mode in Windows 11, but this is a temporary solution and may not provide full stability or security. As a last resort, for absolutely essential legacy applications that don’t have a replacement, you can consider virtualizing them or keeping them on dedicated, properly secured workstations running the previous system, but keeping in mind the risks associated with lack of support.

How to automate Windows 11 deployment?

For organizations with dozens, hundreds or even thousands of computers, manually installing Windows 11 on each device is inefficient, time-consuming and prone to human error. Therefore, a key element of a smooth migration is the use of tools and techniques to automate the deployment process. Modern unified endpoint management (UEM) platforms or dedicated operating system distribution solutions offer extensive capabilities in this regard, allowing to significantly streamline and accelerate migration.

Automated deployment brings numerous benefits. First, it ensures configuration consistency across all devices, minimizing the risk of problems arising from individual settings. Second, it significantly reduces the time required to install the system and core applications, resulting in less disruption to users. Third, it enables the deployment of the system in controlled waves (called deployment rings), allowing you to monitor progress, respond quickly to any problems and gradually get your organization accustomed to the new environment. This process can include automatic backup of user data, installation of drivers, corporate applications and configuration of security policies.

When planning an automated deployment, effective communication with users is also extremely important. They should be informed early on about the migration schedule for each group, the expected time of computer unavailability and the steps they may need to take after the installation is complete. Clear instructions and proactive technical support will help minimize the stress of the change and ensure a positive first impression of Windows 11. Harnessing the potential of automation, coupled with professional planning, demonstrates a commitment to operational excellence and effective management of digital transformation in the organization.

How to prepare users for the new Windows 11?

The introduction of a new operating system, such as Windows 11, is not only a technological change, but also a change for the users who will use it on a daily basis. A new interface, modified functionalities or a different layout of some options can initially be challenging and cause resistance. Therefore, a key element in the success of the migration is proper preparation of employees through effective training, clear communication and the provision of readily available support. Investment in this area translates into faster adaptation, higher productivity and greater user satisfaction.

The preparation program should be multifaceted. It is worthwhile to develop differentiated training materials to suit different learning styles and needs. These can include short video guides showcasing key new features (e.g., refreshed Start menu, Snap Layouts and Snap Groups features, Microsoft Teams integration), interactive tutorials, clear step-by-step instructions (quick reference guides) and question-and-answer sessions. Dedicated workshops can be arranged for more advanced users or those with specific roles in the company. It is important that these materials are easily accessible, for example on the company intranet.

Equally important is continuous and transparent communication at every stage of the migration project. Users should be informed of the timeline, the potential benefits of the new system, and where they can seek help if they run into problems. Appointing internal “ambassadors” of the change or “power users” who master the new system early and can support their colleagues can also significantly facilitate the adaptation process. Treating users as partners in the change process (in line with the value of partnership) and proactively addressing their concerns will help build a positive attitude and ensure a smooth transition to Windows 11.

Key lessons for safe migration to Windows 11:

  • Don’t delay action: The deadline of October 14, 2025 is final. Proactive planning and starting the migration process now is key to avoiding security risks, compatibility issues and business disruptions.
