Who this licence is for

Suited to business PCs and to anyone whose hardware or software is not ready for Windows 11 but who still needs the professional features.

Delivery and activation

Your product key and the download link are sent to the email address you use at checkout, straight after your payment is confirmed. A step-by-step activation guide comes with it, and if a key ever fails to activate we replace it free of charge.

Good to know

Windows 10 Pro runs on hardware that does not meet the Windows 11 requirements – there is no TPM 2.0 or Secure Boot condition here. If your PC does meet those requirements, the Windows 11 Pro key is the newer generation with the same professional features.

How activation works

Your product key arrives by email about 60 seconds after payment. Windows itself comes straight from Microsoft.

Full activation guarantee

Whatever the problem, we make sure your licence gets activated. If a key cannot be activated, we replace it free of charge – with no time limit.

How these reviews are collected After every order Trusted Shops sends an invitation to review us. We cannot edit, select or delete what customers write — the reviews are stored and published by Trusted Shops, not by us.
Frequently asked questionsEverything buyers usually want to know before they order.
How quickly will I receive my licence key?
As soon as your payment is confirmed. Your key, the official download link and step-by-step instructions arrive by email. If nothing has arrived after a few minutes, check your spam folder and then get in touch; we will resend it straight away.
Is this a genuine licence?
Yes. Every key is a brand-new, unused manufacturer licence and stays valid permanently.
How long is the licence valid?
Permanently. You pay once and the licence does not expire. There is no subscription and no recurring fee.
On how many devices can I use it?
One device per licence. If you need several, simply order the matching quantity. For larger volumes write to us and we will quote you a price.
How do I activate my licence?
Your email contains the key, the download link and a step-by-step guide. Follow it once and the licence stays on your device permanently. If you would like someone to walk you through it, message us with your order number. Your purchase is also covered by TheUnitySoft buyer protection.
Where do I find my invoice and my keys?
In your account. Sign in and open My account → Orders — your licence keys, download links and the invoice for every order are stored there permanently.
Can I get help with installation?
Yes. Write to us by email or WhatsApp and a real person will help you with the download, the installation and the activation. Support is included, not an extra.
Still unsure about something? Talk to us — we answer every message.
