Frequently Asked Questions

Everything you should know before buying

Case law on used software

As the highest judicial authority of the European Union, the Court of Justice of the European Union (CJEU) provided final clarity with its ruling and declared the trading of used computer programs fundamentally lawful.

The CJEU also ruled that trading in used software is permissible even when the software is transferred online.

On July 17, 2013, the Federal Court of Justice fully confirmed the CJEU’s landmark decision with regard to the underlying legal questions. 

The CJEU ruling also applies to volume licenses and their splitting. This was confirmed by the Higher Regional Court of Frankfurt am Main in proceedings between Adobe and usedSoft.

In their reasoning, the 13 judges of the Grand Chamber clearly established that the exhaustion principle applies to every first sale of software. The CJEU even ruled that a subsequent purchaser may download the software again from the manufacturer in the case of licenses transferred online: “Furthermore, the exhaustion of the distribution right extends to the program copy in the version improved and updated by the copyright holder,” the CJEU stated. The Court thus went significantly beyond the opinion of the CJEU Advocate General of April 24, 2012.

VOLUME LICENSES AND THEIR SPLITTING ALSO LEGAL

In a later ruling by the Higher Regional Court of Frankfurt am Main in proceedings between Adobe and usedSoft, the further implications of the CJEU ruling were impressively confirmed: The Frankfurt Higher Regional Court held that the CJEU ruling also applies to volume license agreements and their splitting. The Federal Court of Justice dismissed Adobe’s appeal in its entirety on December 11, 2014 (Case No. I ZR 8/13). This conclusively confirmed the Frankfurt Higher Regional Court’s ruling.

Windows 11 Pro

Experience Increased Productivity with Microsoft Windows 11 Pro

With Windows 11, Microsoft has developed a modern operating system that builds on the strengths of Windows 10 and offers numerous visual and functional improvements. Purchasing Microsoft Windows 11 Pro is the ideal solution for professional users, businesses, and organizations. Unlike the Home version, Windows 11 Pro offers additional security features such as BitLocker encryption and Windows Information Protection (WIP). Its extensive features also include mobile device management, Windows Update for Business, support for Azure Active Directory, Hyper-V virtualization technology, Windows Defender Application Guard (WDAG), and advanced Remote Desktop features. With a Windows 11 Pro product key, you benefit from a user-friendly and efficient operating system that significantly boosts your productivity.

Windows 11 Pro Features at a Glance

  • Secure BitLocker encryption
  • Snap layouts for easy window arrangement
  • Auto HDR for enhanced graphics in games
  • A wide range of widgets for individual needs
  • Support for Azure Active Directory
  • Optimized multi-window management
  • Integrated Microsoft Store for businesses
  • Windows Defender Application Guard (WDAG)

Latest Updates for Windows 11 Pro

Windows 11 introduces many innovative features that will fundamentally transform your user experience. The PC remains the leading platform for gaming, and Microsoft is leveraging its experience from the Xbox ecosystem to improve gaming performance on PCs. The introduction of the DirectStorage API makes it possible to load game data directly into GPU memory. In addition, the Auto HDR feature ensures that games developed with DirectX 11 or later are automatically displayed in a vibrant HDR standard. This technology significantly improves contrast and color brilliance. Windows 11 Pro also offers comprehensive support for multiple windows, allowing the operating system to remember the positions of your windows and automatically restore them when you reconnect to a display. This is particularly beneficial for users who frequently switch between different work environments.

Additional Benefits When Purchasing Windows 11 Pro

A license for Windows 11 Pro gives you access to numerous advanced features compared with the Home version, including virtualization support. The Home version includes neither Hyper-V nor Windows Sandbox. Although it can be used as a Remote Desktop client, it cannot function as a host, which limits access to a Windows 11 home computer through Microsoft Remote Desktop. These features are fully implemented in the Pro version. Hyper-V is an integrated tool that allows you to create virtual machines. This enables you to test different operating systems or use older versions of Windows without affecting your host computer.

Virtual machines do not affect the configuration of your primary system, minimizing the risk to your data. Since many business users process sensitive information, Windows 11 Pro offers additional security features, including BitLocker encryption. Windows Information Protection (WIP) prevents employees from sharing sensitive company data with third parties. Because WIP is integrated directly into Windows, it provides a seamless user experience that is easier to manage than third-party solutions. In addition, personal and business data can be stored separately on the same device, and if the computer is lost or stolen, company data can be deleted remotely without affecting personal data.

Windows 11 Pro enables IT administrators to apply group policies to manage multiple devices simultaneously. When you purchase Windows 11 Pro from our store, you are well equipped to meet a range of business requirements.
