Migrating to Windows 11 Pro: A Practical Guide for Slovenian Businesses

October 14, 2025, is marked in red in the IT world. That is when support officially ends for Windows 10, the operating system powering the vast majority of business computers in Slovenia. Although this date seems far away, it is high time for companies to start seriously considering their next step. That step is the migration to Windows 11 Pro. It is not just a cosmetic upgrade; it is a strategic decision affecting the security, productivity, and long-term stability of your entire IT infrastructure. This guide is intended for Slovenian small and medium-sized enterprises wishing to carry out the transition in a planned, efficient manner without unnecessary business interruptions.

Why is now the right time to plan your Windows 11 Pro migration?

Procrastination is not a smart strategy when dealing with a critical business tool like an operating system. The main reason for immediate action is the approaching end of support for Windows 10. Furthermore, Windows 11 Pro brings concrete advantages that can improve your daily operations.

Windows 10 End of Support: What does it mean in practice?

After October 14, 2025, Microsoft will no longer provide security updates or technical support for Windows 10. For your company, this means:

• Increased security risks: Your systems will become easy targets for malware, ransomware, and other cyberattacks, as newly discovered vulnerabilities can no longer be patched.
• Compatibility issues: New software and hardware may no longer be tested or supported on Windows 10, which can lead to instability and loss of functionality.
• Regulatory non-compliance: Using an unsupported operating system may conflict with GDPR requirements and other standards (e.g., ISO 27001) that require proper security risk management.
• Higher long-term costs: Resolving issues arising from using an obsolete system can be significantly more expensive than a timely upgrade.

Business benefits of Windows 11 Pro

Migration is not just a defensive move. Windows 11 Pro is designed for the modern, hybrid way of working and brings several improvements:

• Built-in improved security: With requirements like TPM 2.0 and Secure Boot, plus built-in features like Virtualization-Based Security (VBS), Windows 11 is significantly more resilient to attacks.
• Greater employee productivity: A redesigned, more intuitive user interface, features like Snap Layouts for better window organization, and tighter integration with Microsoft Teams facilitate focused work.
• Simplified management for IT: For IT departments or external partners, Windows 11 Pro allows for easier and more centralized management via tools like Microsoft Endpoint Manager and Intune Autopilot.
• Optimization for hybrid work: Improvements in multi-monitor management, easier desktop switching, and better support for remote access are key for companies with flexible work schedules.

Key steps for a successful migration to Windows 11

1. Phase 1: Inventory and analysis. Inventory of all computers and checking compatibility with TPM 2.0.
2. Phase 2: Application compatibility testing for all key business solutions (ERP, CRM, accounting).
3. Phase 3: Choosing a deployment method – in-place, clean install, or Intune Autopilot.
4. Phase 4: Pilot program with a small group of users.
5. Phase 5: Gradual deployment department by department.
6. Phase 6: Communication and training for employees.

Hardware requirements: The most common obstacle

Automated migration with Intune Autopilot

For companies looking to simplify the process, Intune Autopilot is the best solution. It enables so-called "zero-touch deployment": IT registers the device, the user turns it on, and it automatically configures itself to company standards.

When do we need to perform the migration?

Windows 10 support ends on October 14, 2025. We recommend completing the migration well before then.

Do we need to replace all incompatible computers?

If they do not meet the requirements (TPM 2.0), an official upgrade is not possible – replacement is necessary.

Difference between Windows 11 Home and Pro?

For businesses, Pro is essential: BitLocker, Group Policy, Intune, Windows Update for Business.

What is the ESU program?

Extended Security Updates for Windows 10 for up to 3 years – a more expensive temporary solution.
