You haven't bought this product from Licendeals, so your review won't show the "Verified purchase" label and won't count towards the rating. Review only the software you have used yourself. These reviews don't earn points. Every review and image is checked against our Review Rules before it appears.

The name you enter is shown with your review, so we suggest your first name and the initial of your last name. Your email address is required but never published. We use it only to check your review and, if needed, to contact you about it. See our Privacy Policy.

JPG, PNG or WebP, up to 5 MB each, up to 4 images. We remove location and camera data from your images. Images are checked before they appear, and images with license keys or personal details are not published.

Reviews marked "Verified purchase" are from customers who bought this product from Licendeals. Reviews without that label are from people who say they have used the product but didn't buy it from us. We don't check that they have used it, and their reviews don't count towards the rating. Customers with an account receive Choice Rewards points for each published Verified purchase review with an approved photo showing the product activated, whatever their rating, and these reviews are labelled to show it. We approve photos only on what they show, never on the rating or opinion. Anyone can reply to a review. We check every review, image and reply before it appears, publish every one that follows our Review Rules, positive or negative, and don't change what people say, except to remove personal details, license keys or images that break the rules.

Questions about this license

Can I upgrade from Windows Home?

Yes, from Windows Home (not Home Single Language). Enter the Pro key in Settings, System, Activation, Change product key. Your files and apps stay where they are.

How fast do I get my key?

Right away: we email you a secure link to your license as soon as your payment is confirmed. It also appears in your account.

How long do I have to activate it?

There is no rush: your key waits safely until you reveal it, even months later. Once you reveal it, activate it within 24 hours. Activated in time, it's covered for life, for as long as you use it on the computer where you activated it. CID Licenses activate once per computer: if you later reinstall the software or the operating system, or change the computer's hardware, that activation can't be used again, and our warranty doesn't cover it. Warranty details

What if the key does not activate?

Write to us on chat or WhatsApp within 24 hours of revealing your key, and we'll replace it right away.

Can I get a refund?

Yes, within 30 days, as long as you haven't revealed the license. Once it's revealed, it can't be refunded, unless the law of your country requires it, so only reveal it when you're ready to activate it.

Which payment methods do you accept?

Card and crypto.
