Frequently asked questions
What do I get after the purchase?
You receive by e-mail the Windows 11 Pro product key, a download link to the 64-Bit ISO as well as an installation guide in English and an invoice showing the VAT.
What is a volume licence?
Volume licences are licences from Microsoft volume licensing agreements such as Open License, Open Value or MPSA. Functionally they are identical to retail licences – they simply use a different activation method (MAK instead of a retail key).
How do I activate Windows 11 Pro with the volume licence?
Activation works just like any other Windows licence: Settings → System → Activation → Change product key. Enter the 25-digit key, and activation then runs automatically via the Microsoft servers.
What are the differences from the retail version?
Functionally none. Both versions provide the same features, the same Windows 11 Pro and the same updates. The difference lies in the activation method: volume licences use MAK keys, retail licences use classic product keys.
Does my PC meet the requirements (TPM 2.0, Secure Boot)?
Microsoft provides a free tool called the PC Health Check that checks your device's compatibility with Windows 11. Most PCs from 2018 onwards meet the requirements.
On how many PCs can I install it?
This licence is intended for activation on a single PC. Parallel use on multiple computers is not permitted.
Is the resale legally permitted?
Yes. The EuGH ruling C-128/11 "UsedSoft/Oracle" of 03.07.2012 as well as the BGH ruling I ZR 129/08 "UsedSoft II" of 17.07.2013 confirm the resale of used software licences – including volume licences – within the EU.
What about the right of withdrawal?
With the activation of the key, the right of withdrawal expires in accordance with § 356 (5) BGB. For unactivated keys, the 100-day money-back guarantee from Karinex applies.
