Why buying Windows 10 is still a good choice 

For years, Windows 10 has been one of the most widely used operating systems in both everyday life and business – primarily due to its high level of compatibility with existing hardware, drivers and business software. Especially if you wish to continue using a PC that is not compatible with Windows 11, or if certain programmes or peripherals are known to run stably on Windows 10, Windows 10 can still be a sensible choice. 

It is important, however, to take a realistic view: official support for Windows 10 ended on 14 October 2025. Since then, Microsoft has no longer been providing regular security updates, feature updates or technical support for Windows 10. This does not mean that Windows 10 ‘no longer works’ – but using it securely in the long term requires greater care (e.g. up-to-date third-party security solutions, careful patch and update management for applications and browsers, and, where necessary, using separate systems for specific tasks). For a long-term, future-proof and maximally secure environment, Microsoft recommends upgrading to the latest version, Windows 11. 

In short: Windows 10 remains a viable option where compatibility and manageable deployment scenarios are the priority – though the end of support should be borne in mind. 

Windows 10 Home, Pro or Enterprise – which version is right for you? 

Windows 10 Home 

Windows 10 Home is aimed at home users and is ideal if you need Windows for typical tasks such as web browsing, Office, streaming, multimedia and everyday use. You get the basic Windows features, a familiar user interface and broad hardware support. 

Windows 10 Professional 

Windows 10 Professional (Pro) is the right choice if you need advanced features for work, self-employment or business – particularly in terms of management, security and networking. 

Windows 10 Enterprise 

Windows 10 Enterprise is generally intended for larger organisations and is usually provided via volume licence programmes. In addition to the features of the Pro edition, it includes further enterprise features for centralised management and security (depending on the licence/contract model).

 Windows 10 system requirements 

To ensure Windows 10 runs smoothly, the minimum requirements must be met. Microsoft specifies the following requirements, amongst others: 

  • Processor: 1 GHz or faster processor or SoC 
  • RAM: 1 GB (32-bit) or 2 GB (64-bit) 
  • Storage space: 32 GB or more (for newer versions of Windows 10) 
  • 32/64-bit: depends on the CPU and desired RAM usage (64-bit is generally advisable in most cases these days)

Activating Windows 10 – here’s how it works 

  1. Install Windows 10 (e.g. via USB stick/ISO) – Microsoft provides the official ISO download. 
  2. After installation, open: Settings → Update & Security → Activation 
  3. Click on ‘Change product key’ 
  4. Enter the product key and confirm 
  5. Windows will verify the key and activate the system 

Tip: If you’re unsure whether 32-bit or 64-bit is suitable: For 64-bit, you need a 64-bit-capable CPU; the benefits are particularly noticeable with more RAM (e.g. 4 GB or more). 

Buy a Windows 10 licence now at an affordable price and install it straight away 

If you’re looking for a tried-and-tested version of Windows for existing devices or compatible software environments, Windows 10 remains a practical solution – with fast digital delivery, simple activation and German-language support. Be sure to note the end of support date and plan a modern Windows strategy in the medium term to ensure maximum security.

FAQ: Frequently Asked Questions: Windows 10

Yes, Windows 10 product keys can still be purchased from us. Microsoft continues to provide official download options (ISO/installation media) for the installation itself.

The attractive price is primarily due to the current market situation. Windows 10 has been on the market for several years now, and official support expired in October 2025. As a result, demand is lower compared to newer versions, which has a positive effect on the price.

At Lizenzdeals24, you will, of course, receive a genuine, permanently valid licence key – at a fair price and with transparent invoicing.

In principle, it is possible to upgrade from older versions of Windows. Microsoft points out that certain prerequisites must be met for a direct upgrade – for example, Windows 7 with Service Pack 1 or Windows 8.1 with the latest updates installed.

In practice, however, the recommended approach always depends on your specific circumstances: Whether a direct upgrade is advisable or a clean reinstallation is the better solution depends on the version, the system’s condition and the hardware.

If you are unsure, we will be happy to assist you personally. Our support team at Lizenzdeals24 will help you find the right approach for your system and assist you with any questions regarding installation and activation.

Support expired on 14 October 2025. Windows 10 will continue to run, but Microsoft no longer provides regular security updates, bug fixes or technical support for it. To ensure long-term security, we recommend upgrading to a current version of Windows.
The main difference lies in the RAM and performance. The 32-bit version can use a maximum of 4 GB of RAM, whilst the 64-bit version supports significantly more RAM and is therefore more powerful. Furthermore, the 64-bit version can run both 32-bit and 64-bit programmes. Windows 10 64-bit is therefore generally recommended for modern PCs with 4 GB of RAM or more.
