Why Buy Your Windows 11 Key at Revolution Soft?
At Revolution Soft we sell genuine Microsoft Windows 11 license keys at a fraction of the official price. This is possible because we sell pre-owned licenses (also known as surplus or second-hand licenses), whose resale within the European Union has been fully legal since 2012, when the Court of Justice of the European Union issued Ruling C-128/11 (UsedSoft vs Oracle). This ruling established that the distribution right of a software program is exhausted after the first sale, legally allowing the resale of legitimate software licenses.
Every Windows 11 license you purchase in our store is a genuine Microsoft product key that activates directly on Microsoft's official servers and receives all security and feature updates just like any other license. We also issue an invoice with VAT, making our licenses valid for individuals, businesses and public bodies alike, including full compliance with software audits.

Windows 11 Pro vs Windows 11 Pro OEM — Which One Should You Choose?
The main difference between a standard Windows 11 Pro (Retail) license and a Windows 11 Pro OEM license is transferability. The Retail license can be moved from one computer to another: if you change your PC or reformat, you can reuse the same key on your new machine. The OEM license, on the other hand, is tied to the hardware where it is first activated and cannot be transferred to another device — but it is identical in functionality and has the same price in our store.
If you plan to change your computer in the future, choose the Retail license. If the license is for a fixed machine that you won't be replacing (for example, an office desktop PC), the OEM is an excellent option at the same price.
Windows 11 Home vs Windows 11 Pro — Key Differences
Windows 11 Pro includes everything in Windows 11 Home plus essential professional tools: BitLocker (full-disk encryption), Remote Desktop (as host), Hyper-V (virtualisation), Group Policy (GPO), Active Directory domain join, and Windows Sandbox. For professional or business use, the Pro edition is the recommended choice.

Frequently Asked Questions About Windows 11 Licenses
|
How much does a Windows 11 license cost?
Microsoft's official price for Windows 11 Pro is €259. However, at Revolution Soft you can buy a genuine Windows 11 Pro license from just €27.75, saving 89%. These are pre-owned licenses whose resale is legal in the EU (CJEU Ruling C-128/11). All our licenses include an invoice with VAT, instant email delivery and lifetime warranty.
|
|
|
Is it legal to buy cheap Windows 11 keys?
Yes, it is completely legal within the European Union. The Court of Justice of the EU established in its Ruling C-128/11 (UsedSoft vs Oracle, July 2012) that the distribution right of software is exhausted after its first sale. This means the resale of legitimate software licenses is legal, provided the original owner has deleted their copy. Revolution Soft is a Spanish-registered company (S.L.) that complies with this regulation and issues invoices with VAT.
|
|
|
Is the Windows 11 license permanent?
Yes. The Windows 11 licenses we sell at Revolution Soft are perpetual (lifetime) licenses. Once activated, your license does not expire, requires no renewal and has no additional cost. You will continue to receive all Microsoft security and feature updates for as long as Windows 11 has official support. We also offer a lifetime warranty on all our licenses: if your key has any issue, we replace it at no cost.
|
|
|
Can I activate Windows 11 on more than one computer?
Each standard Windows 11 Pro (Retail) license allows you to activate one computer at a time. However, you can transfer it to another PC if you deactivate the license on the previous one. OEM licenses, on the other hand, are permanently tied to the hardware where they are first activated. If you need licenses for multiple devices, we have 10-pack and 50-pack bundles with volume discounts.
|
|
|
Can I upgrade from Windows 10 to Windows 11 with these keys?
Yes. If your computer meets the Windows 11 hardware requirements (compatible processor, TPM 2.0, Secure Boot, 4 GB RAM and 64 GB storage), you can use the product key from Revolution Soft to activate Windows 11 after upgrading. You can also do a clean install from scratch by downloading the official ISO from Microsoft using the Media Creation Tool.
|
|
|
Are these licenses valid for businesses and software audits?
Yes. Our Windows 11 licenses are fully valid for businesses, freelancers and public organisations. They activate on Microsoft's official servers, include an invoice with VAT and comply with the CJEU Ruling C-128/11 that authorises legal software resale in the EU. This makes them suitable for passing Microsoft software audits or other compliance reviews.
|
|
|
What is the difference between Windows 11 Home and Pro?
Windows 11 Pro includes everything in Windows 11 Home plus professional features: BitLocker (full-disk encryption), Remote Desktop as host, Hyper-V for virtualisation, Group Policy (GPO), Active Directory domain join and Windows Sandbox. The Pro edition is recommended for professionals, businesses and any user who needs advanced security and management capabilities.
