Buying a Microsoft software licence online means trusting your seller. With deals that look too good to be true, invalid keys and scams on some marketplaces, it's natural to ask: where can you buy Microsoft licence keys safely, at a fair price and with professional service?
Yeslicense has been answering that question for several years. Specialising in genuine digital Microsoft licences — Windows, Office, Windows Server, SQL Server, Visio, Project — as well as EaseUS software, Yeslicense has become a go-to store for home users, professionals and businesses who want to equip their computers without overspending.
Here are the main reasons thousands of customers choose Yeslicense over other resellers.
1. 100% Genuine Microsoft Licence Keys That Activate With Microsoft
The first question every buyer asks is a fair one: "will the key I buy actually work?"
At Yeslicense, every licence key is 100% genuine and activates directly with Microsoft's servers, with no third-party software, cracks or patches. When you enter your key in Windows or Office, it's Microsoft's own activation system that validates the licence.
Our licences are sourced through legitimate distribution channels. They don't come from compromised accounts, key generators or workarounds. Every key sold on Yeslicense is genuine, unique and valid.
If there's ever an activation problem — which is extremely rare — our team sends you a replacement key straight away. 100% satisfaction guaranteed.
2. Prices Well Below Retail
Buying a boxed licence in a shop or directly from Microsoft can be expensive. On Yeslicense, the same Windows and Office licences are available for a small fraction of the usual retail price — check each product page for the current price.
These price differences can seem surprising. They come down to the distribution model: Yeslicense operates purely digitally, with no boxes, no physical logistics and no retail middlemen. This lean cost structure lets us pass the savings straight on to the customer.
Our most popular licences include:
- Windows 11 Pro
- Windows 10 Pro (Windows 10 support ended on 14 October 2025; extended security updates for consumers run until 12 October 2027)
- Office 2021 Pro Plus (support ended on 13 October 2026)
- Office 2024 Pro Plus
- Office 2024 + Windows 11 Pro bundle
- Windows Server 2022 Standard
For businesses that need to equip several workstations, the savings add up quickly: a small business equipping every PC with Windows 11 Pro and Office Pro Plus saves a considerable amount compared with full retail pricing.
3. Instant Email Delivery, Day and Night
At Yeslicense, there's no waiting. As soon as your payment is confirmed, your licence key is sent automatically to the email address you gave when ordering.
The process is fully automated and runs 24 hours a day, 365 days a year. Whether you order on a Sunday at 11:45 pm or on a bank holiday, your key arrives in your inbox within minutes — often in under 5 minutes.
That's a major advantage in urgent situations: a broken PC, an emergency Windows reinstall, or an upgrade needed before an important meeting. With Yeslicense, you don't lose a working day waiting for delivery.
4. A Complete Range of Microsoft Licences and Related Software
Yeslicense isn't a single-product reseller. Our range covers the whole Microsoft software ecosystem that home users and businesses need:
Windows operating systems
Windows 11 and Windows 10, Home or Pro editions, as individual or volume (MAK) licences, for one PC or hundreds. Highlights include:
— Windows 11 Pro
— Windows 11 Pro MAK — Volume Licence for Businesses
— Windows 10 Pro
Microsoft Office suites
Perpetual versions of Office for Windows and Mac, as single or multi-PC licences. Office 2024 is the current version; Office 2016 and 2019 no longer receive security updates, and Office 2021 support ended in October 2026:
— Office 2024 Pro Plus
— Office 2021 Pro Plus
— Office 2021 Home & Business for Mac
Windows Server and infrastructure
Licences for every edition of Windows Server, SQL Server and Client Access Licences:
— Windows Server 2016, 2019, 2022 and 2025
— Microsoft SQL Server 2022
— RDS CALs for Remote Desktop deployments
Microsoft productivity tools
— Microsoft Visio 2021 and Project 2021 for system architects and project managers
EaseUS software
Yeslicense also sells the full EaseUS range: data recovery, backup, partition management, corrupted file repair and system deployment.
5. Clear Information and Responsive Customer Support
Yeslicense is built to make buying simple. Product pages, order emails and activation instructions are clear and easy to follow, which helps you understand each offer and avoid the misunderstandings that can happen on some marketplaces.
Our support team is available 7 days a week by email and chat, in English or French. If you have a question before buying, an activation problem, or need help choosing the right licence, our team will answer quickly.
It's an often underestimated advantage, especially for businesses that need proper invoices, quick quotes or business-oriented technical advice.
6. Perpetual Licences — Pay Once, No Subscription
All Microsoft licences sold on Yeslicense are perpetual licences. Once purchased, the software is yours to keep. No monthly or annual subscription, no renewals to plan for, no surprises at the end of the year.
This contrasts with the Microsoft 365 subscription model, which is billed monthly or yearly per user. For a small business, those recurring costs add up year after year just for office software.
With a perpetual Office 2024 Pro Plus licence bought on Yeslicense, you pay once and use the software throughout its life cycle (Microsoft support for Office 2024 runs until October 2029). The return on investment is immediate and measurable.
Of course, perpetual licences don't receive new features continuously like Microsoft 365, and Office 2024 perpetual doesn't include Copilot. But for the vast majority of business tasks — word processing, spreadsheets, presentations, email — Office 2024's features are more than sufficient.
7. Offers Designed for Businesses and IT Professionals
Beyond single licences, Yeslicense offers solutions designed specifically for businesses and IT professionals.
MAK volume licences
Windows 11 Pro MAK and Windows 10 Pro MAK licences let you activate Windows on dozens or hundreds of PCs with a single multiple-activation key. They're designed for volume deployments in businesses, public bodies and schools.
Multi-PC Office licences
Yeslicense offers Office licences for 3, 5 and 50 PCs, as well as MAK licences for very large deployments. Our tiered pricing helps IT departments optimise their software budget while staying fully compliant.
Complete server infrastructure
For IT managers and system administrators, Yeslicense offers every building block of a Microsoft infrastructure: Windows Server 2016 to 2025, SQL Server 2022, user CALs and RDS CALs. All are available digitally with immediate activation.
EaseUS IT software for technicians
The Technician editions of EaseUS software (Data Recovery, Partition Master, Todo Backup) are available on Yeslicense with unlimited commercial usage rights — ideal for MSPs and IT service providers.
8. A Simple, Fast and Secure Checkout
Yeslicense is designed so that buying a licence takes less than 3 minutes, from finding the product to receiving the key in your inbox.
Here's how a typical purchase works:
- Browse the site and find the licence you need using collections organised by category (Windows, Office, Server, EaseUS, Games).
- Add the product to your basket and go to the order summary.
- Pay using one of the many secure payment methods accepted (bank card, PayPal and more).
- Your licence key is sent automatically to your email address within minutes.
- Activate your software by following the instructions included in the email.
Payments are processed by secure, PCI-DSS-compliant providers. Your card details are never stored on our servers.
9. Detailed Product Pages for an Informed Choice
One of the challenges of buying software licences is understanding exactly what you're buying. Microsoft's ranges are complex: Home vs Pro, Standard vs Datacenter, 1 PC vs multi-PC, OEM vs Retail, MAK vs KMS… Without clear information, it's easy to pick the wrong version.
On Yeslicense, every product page sets out:
- The features included in that version
- The differences from other versions in the same range
- The system requirements
- A step-by-step activation guide
- An FAQ answering buyers' common questions
- Links to complementary products to build the right solution for your needs
This transparency helps you make an informed decision and never pay for a licence that doesn't match your needs.
10. Activation Guarantee or Your Money Back
Yeslicense offers a full satisfaction guarantee. If your licence key doesn't activate correctly with Microsoft's servers, you have two immediate options:
- Immediate replacement: our team sends you a new working key without delay.
- Full refund: if a replacement doesn't solve the problem, you get your money back in full.
This guarantee reflects our confidence in the quality of the licences we sell. Activation problems are extremely rare at Yeslicense, but they can happen for technical reasons outside our control (hardware changes, Microsoft system checks). Either way, you're covered.
Conclusion: Yeslicense, the Smart Choice for Microsoft Licence Keys
Choosing Yeslicense means choosing a service that combines the three things every buyer wants: genuine keys, competitive prices and reliable service.
The licences we sell are the same Microsoft software you'd find in a specialist shop, offered at a fraction of the price, with instant delivery and 7-day support by email and chat.
Whether you're setting up a family PC, a freelancer who needs a professional office suite, a small business managing a fleet of computers, or an IT technician looking for data management and recovery tools, Yeslicense has the licence you need at a fair price.
