Buy Windows Operating Systems – Windows 11, 10, 8 & 7 Licences

Microsoft Windows is the most widely used desktop operating system in the world. This category belongs to the Operating systems section. At Lizenzindustrie you get all current and older Windows operating systems as verified licences – affordable and with the licence key sent by email.

Whether for your home computer, a professional workstation or business use – we stock all Windows editions as single and volume licences.

Windows 11 – the latest Windows operating system

Windows 11 is the current generation of the Microsoft operating system. Modern design, Snap Layouts, DirectStorage and Auto HDR for games, plus mandatory TPM 2.0 security, make Windows 11 the future-proof choice.

• Windows 11 Home – For home users: the full Windows 11 feature set, Microsoft Store, DirectX 12 Ultimate and automatic security updates.
• Windows 11 Pro – For businesses and advanced users: BitLocker encryption, Azure AD join, Hyper-V and Windows Update for Business.
• Windows 11 Pro volume licence – For businesses with multiple workstations: centrally manageable, flexibly scalable, cost-efficient.
• Windows 11 Enterprise – Maximum security for large enterprises: Microsoft Defender for Endpoint, Windows Hello for Business and AppLocker.
• Windows 11 Education – For schools and educational institutions: favourable licensing terms, extended management options and education apps.

Windows 10 – for existing systems

Windows 10 still runs on many computers, and IT departments value its broad software compatibility. For new devices and long-term use, however, we recommend Windows 11.

• Windows 10 Home – For home users: reliable, secure and with all the important Windows features for everyday use at home.
• Windows 10 Pro – The best-selling business edition: BitLocker, Remote Desktop, Group Policy management and domain join.
• Windows 10 Pro volume licence – For businesses needing multiple licences: flexible activation, central management and attractive volume pricing.
• Windows 10 Enterprise – For large enterprises: AppLocker, Windows Defender Application Guard and LTSC for maximum system stability.
• Windows 10 Pro for Workstations – For high-end hardware: up to 6 TB of RAM, NVMe RAID and the ReFS file system. Ideal for CAD, video editing and science.
• Windows 10 Education – For pupils, students and teachers: the full feature set on favourable education terms.

Windows 8 & Windows 8.1 – for special applications

Today, Windows 8 and Windows 8.1 are used mainly in environments where legacy software or special compatibility requirements call for exactly these versions. For businesses with such needs, we offer selected licences.

Our recommendation: Windows 8 and 8.1 are the right choice if existing systems or specialist software are tailored to them. New computers are better equipped with Windows 11.

• Windows 8.1 Pro – With domain join, BitLocker encryption and Hyper-V support for professional environments.
• Windows 8.1 Home – The basic version for home users with core features for everyday use.

Windows 7 – the classic for legacy systems

Many industrial companies, production facilities and medical institutions still rely on Windows 7 because specialised software does not allow a switch to a newer Windows version.

Note: We recommend Windows 7 mainly for equipment and programs that are firmly tied to this version. For all new installations, Windows 11 is the better choice.

• Windows 7 Professional – Domain join, Remote Desktop and professional networking features for business environments.
• Windows 7 Ultimate – The most comprehensive Windows 7 edition with all available features.
• Windows 7 Home Premium – The proven home version for everyday tasks and multimedia use.

Frequently asked questions about Windows licences

Which Windows version is right for me?

For home users we recommend Windows 11 Home. For businesses and professional users, Windows 11 Pro is the best choice. Windows 10 Pro is mainly an option if a particular piece of software strictly requires Windows 10. If you want to buy several computers' worth of Windows and Office together, the Windows 11 & Office bundle offers a suitable combination.

Where do the Windows licences at Lizenzindustrie come from?

We source our licences from distributors and wholesalers in Europe. We explain exactly how this works on our Buying legal software page.

Can I upgrade from Windows 10 to Windows 11?

Yes – provided your hardware has TPM 2.0, UEFI and a compatible 64-bit CPU. Microsoft's “PC Health Check” app shows whether your PC is suitable.

What is the difference between OEM and retail?

An OEM licence remains tied to the first computer on which it was activated. You may take a retail licence with you when you change devices, provided it is no longer used on the old device.

How quickly will I receive my licence key?

Usually within a few minutes of your payment being received – the key is sent by email. You then activate Windows via the official Microsoft servers; instructions are included.
