Tietoja tästä lisenssistä
Microsoft Windows 8.1 Pro — The Bridge Between Classic and Modern Windows
Windows 8.1 Pro refined the Windows 8 experience with the Start button return, improved multitasking, and better desktop integration. A solid choice for systems that need modern security with touch-friendly capabilities.
What You Get
Restored Start Button — familiar navigation with modern live tile integration
Enhanced Multitasking — snap up to 4 apps on screen simultaneously
Domain Join & Group Policy — enterprise management for business network environments
BitLocker Encryption — full-disk encryption to protect business and personal data
Windows To Go — boot your entire Windows environment from a USB drive
Hyper-V Virtualization — run virtual machines natively without third-party software
Why Choose Windows 8.1 Pro?
Windows 8.1 Pro occupies a unique sweet spot — modern enough for current security standards, lightweight enough for older hardware, and compatible with software that doesn't support Windows 10/11. Its touch-optimized interface makes it ideal for tablets and 2-in-1 devices from the Windows 8 era.
Perfect For
Older Hardware that runs best on a lighter, optimized operating system
Touch Devices from the Windows 8 era (Surface Pro 1/2/3, Dell Venue, etc.)
Business Environments requiring specific Windows 8.1 software compatibility
Development & Testing where Windows 8.1 compatibility verification is needed

What are the system requirements for Microsoft Windows 8.1 Pro?
Microsoft Windows 8.1 Pro requires Windows 10/11, at least 4 GB of RAM (though 8 GB is recommended), and 2 GB of free storage space. An internet connection is needed for download and activation.
What kind of license do I get with Microsoft Windows 8.1 Pro from Lizensa?
Your Microsoft Windows 8.1 Pro license is a perpetual (lifetime) license — buy once and use forever on one device. This means no recurring fees or subscriptions. You'll also receive free updates and security patches from Lizensa.
What's included with my Microsoft Windows 8.1 Pro purchase from Lizensa?
Your purchase includes a genuine Microsoft Windows 8.1 Pro license key, a download link from the official Microsoft website, step-by-step activation instructions, a VAT invoice (EU), and lifetime access to the key in your Lizensa account. All keys are authentic and backed by our 14-day money-back guarantee.
Why is Microsoft Windows 8.1 Pro so much cheaper on Lizensa?
At just €12.99, our Microsoft Windows 8.1 Pro license is up to 86% cheaper than retail because we buy in wholesale volume from European distribution channels and pass the savings directly to you. You get the exact same genuine product — just without the retail markup.
How do I install and activate Microsoft Windows 8.1 Pro from Lizensa?
After purchase, you'll receive a download link and license key by email. Download the software from the official Microsoft website, enter your key during installation or in the activation menu, and follow the guided setup. Full instructions are included with your purchase.
Is Microsoft Windows 8.1 Pro compatible with my operating system?
Microsoft Windows 8.1 Pro is compatible with current versions of Windows and macOS. Please check the system requirements section on this page before purchasing. Most modern PCs and Macs meet or exceed the minimum requirements.
How quickly will I receive my license key from Lizensa?
Your license key is delivered instantly via email after payment is confirmed — typically within 30 seconds. You'll also find it in your Lizensa account dashboard under My Library.
Are Lizensa license keys genuine and legal in the EU?
Yes. Our licenses are sourced through European distribution channels and come with a VAT invoice. The EU Court of Justice (UsedSoft v Oracle, C-128/11) has confirmed that software license resale is legal within the European Economic Area.
What is Lizensa's refund policy?
We offer a 14-day money-back guarantee on all licenses. If you encounter any issues with activation or the product doesn't meet your needs, contact our support team for a full refund — no questions asked.
productDetail.faq.activation.question

Do I get support with my Lizensa purchase?
Absolutely. Our multilingual support team responds within one hour during business hours. We can assist with installation, activation troubleshooting, and license questions via email in English, German, French, Spanish, Italian, Dutch, and Polish.
Onko tämä aito, valtuutettu lisenssi?
Kyllä. Hankittu valtuutettujen eurooppalaisten jakelukanavien kautta. Jokainen avain on aito ja jälleenmyytävissä EU:n ”oikeuksien tyhjentymisen” periaatteen mukaisesti (CJEU C-128/11).
Kuinka nopeasti avain saapuu?
Keskimääräinen toimitusaika on 43 sekuntia. Sitoudumme alle 60 sekuntiin. Jos tämä ei toteudu, saat ilmaisen korvaavan avaimen.
Voinko saada hyvityksen, jos se ei sovi minulle?
Kyllä. EU:n kuluttajalaki antaa sinulle 14 päivää aikaa palauttaa käyttämätön avain — ilman kuluja tai kysymyksiä. Kunnioitamme tätä kitkattomasti.
Tarjoatteko ALV-laskun B2B-asiakkaille?
Kyllä. EU-vaatimusten mukainen lasku jokaisen tilauksen mukana, ladattavissa hallintapaneelistasi. Voimassa oleva ALV-numero laukaisee automaattisen käänteisen verovelvollisuuden.
Millä kielillä aktivointiopas on?
EN, DE, FR, ES, NL, PL, IT, PT — valitaan automaattisesti tilisi kielen mukaan.
Mitä jos aktivointi tuottaa ongelmia?
Sähköposti- tai chattituki vastaa omalla kielelläsi tunnin kuluessa EU:n työaikana. Autamme sinua läpi prosessin tai vaihdamme avaimen.
