Buy a Windows 7 Professional License – Perpetual License with Instant Email Delivery
Windows 7 Professional as a perpetual license with unlimited duration for one PC. The proven Pro edition with domain join, Remote Desktop, Encrypting File System (EFS), Group Policies and Windows XP Mode – designed for older hardware, industrial and control PCs, isolated offline workstations and the reactivation of existing Windows 7 installations. Buy once instead of subscribing monthly.
Instant delivery of the Windows 7 Professional product key by email after receipt of payment. Includes a download link to the installation file (original image, 32/64-bit), a step-by-step guide in German and a proper invoice with 19% VAT shown separately.
At Karinex you receive a particularly affordable original license, German-language support, a 100-day money-back guarantee on unactivated product keys and a perpetual license with no subscription commitment.
Important note on support status
Microsoft ended extended support for Windows 7 on 14 January 2020; the paid ESU programme for business customers ended on 10 January 2023. Windows 7 therefore no longer receives official security updates. Windows 7 Professional is specifically suited to older hardware, industrial and offline systems as well as the reactivation of existing installations. For security-critical, internet-facing workstations we recommend Windows 10 Pro or Windows 11 Pro.

License type and legal framework
You are purchasing a pre-owned original license (OEM) for Microsoft Windows 7 Professional for permanent use on one device. The license was first placed on the market within the EU with the consent of the rights holder (Microsoft) and is therefore exhausted.
The conditions for exhaustion under § 69c No. 3 S. 2 UrhG in conjunction with Art. 4(2) of Directive 2009/24/EC are met:
- The initial sale took place within the EU with the consent of the rights holder.
- The previous owner rendered the program copy unusable on their systems (uninstallation and deactivation).
- The license chain is documented and can be disclosed on request.
The independent resale of OEM software is permitted under case law (BGH, judgment of 06/07/2000, I ZR 244/97 "OEM-Version"; EuGH, judgment of 03/07/2012, C-128/11 "UsedSoft/Oracle"; BGH, judgment of 17/07/2013, I ZR 129/08 "UsedSoft II"). The product key can be activated once on one device. Simultaneous use on multiple devices is excluded.

Frequently asked questions
Why is Windows 7 Professional so affordable at Karinex?
We trade pre-owned original licenses under the principle of exhaustion (EuGH C-128/11; BGH I ZR 244/97). This way you receive an original Microsoft license at a particularly low price – with no compromises on originality or activatability.
What do I get after purchase?
You receive by email the Windows 7 Professional product key, a download link to the installation file as well as an installation guide in German and an invoice with VAT.
Does Windows 7 still receive security updates?
No. Extended support ended on 14 January 2020, and the paid ESU programme for business customers on 10 January 2023. For security-critical, internet-facing workstations we recommend Windows 10 Pro or Windows 11 Pro. Windows 7 Professional is the right choice for legacy, offline and industrial scenarios.
Is this a perpetual license?
Yes. Windows 7 Professional is a purchase version with a perpetual license – without a subscription and without recurring costs.
How quickly is delivery made?
After receipt of payment within a few minutes by email. With bank transfer, 1–2 business days.
What distinguishes Professional from Home Premium?
Only Professional offers domain join, Remote Desktop as a host, the Encrypting File System (EFS), Group Policies and Windows XP Mode.
What distinguishes Professional from Ultimate?
Ultimate adds BitLocker drive encryption, AppLocker and multilingual packages (MUI) to Professional. If you do not need these features, Professional is the right and more affordable choice.
32-bit or 64-bit?
Both variants are included. 64-bit is recommended if your system is to use more than 4 GB of memory.
On how many PCs can I install it?
This license is intended for activation on one PC. Simultaneous use on multiple devices is excluded.
Is resale legally permitted?
Yes. EuGH C-128/11 "UsedSoft/Oracle" (03/07/2012), BGH I ZR 129/08 "UsedSoft II" (17/07/2013) and, for OEM software, BGH I ZR 244/97 "OEM-Version" (06/07/2000) confirm the resale of exhausted licenses within the EU.
What about the right of withdrawal?
Upon activation of the key, the right of withdrawal expires (§ 356(5) BGB). For unactivated keys, the 100-day money-back guarantee applies.
