Windows 11 Professional 5PC: How One Key Activates 5 PCs

How does a Windows 11 Pro 5 PC license work? At Licendeals, Windows 11 Professional 5PC is a RETAIL License with one product key that activates Windows 11 Pro on 5 different computers. Below we explain what you receive, how to enter the same key on each PC, the rules for each activation and when a 5PC license is the right choice, with screenshots from our own store and from our Windows 11 guide.

IMPORTANT: this license does not work for upgrading from Windows 11 Home Single Language. If your computers have Windows 11 Home or Windows 11 Pro, it works as described below.

1. The short answer

One key activates 5 PCs. You buy one Windows 11 Professional 5PC license, you receive one product key, and you enter that same key on each of your 5 computers. Every computer gets its own activation.

This is the product page. Point at the small "i" next to License Type and a short explanation opens:

2. What you receive

The description of the product page sums it up in three lines:

• One license, 5 activations: "You receive 1 license to activate Windows 11 Professional 5 times."
• One key: the same 25-character product key for all 5 computers.
• One activation per computer: the License details tab says "Digital license, one activation per computer" and "5 PCs per license".

We email you a secure link to your license as soon as your payment is confirmed. It also appears in your account.

3. How to activate the same key on each PC

You repeat the same steps on each computer. These are Microsoft's steps for entering a product key in Windows 11:

3.1 On the first computer, select Start, then Settings, System, Activation.

3.2 Next to Change product key, select Change. If the User Account Control window appears, confirm with an account that has administrator rights on that computer.

3.3 Type your 25-character product key and select Next.

The red message in this screenshot means that computer couldn't reach Microsoft's activation servers at that moment: make sure each computer is connected to the Internet when you activate it.

3.4 Check that the Activation page shows Windows 11 Pro as active.

3.5 Repeat steps 3.1 to 3.4 on each of the other 4 computers, with the same key.

If a computer has Windows 11 Home, entering the Pro key upgrades it first. In Microsoft's words: "Select Next to start the upgrade to Windows 11 Pro." The computer restarts and then activates. Our guide How to Upgrade Windows 11 Home to Pro shows that upgrade screen by screen, and How to Activate Windows 11 covers a computer that already has Windows 11 Pro.

4. The rules for each of the 5 activations

Windows 11 Professional 5PC is a RETAIL License, so each of the 5 activations follows the rules on our license types page:

• Devices: "With 5PC products, one key activates up to 5 computers."
• Reinstalling or moving it: each activation can be used only once. If you uninstall or reinstall the software or the operating system (including a reset or a format), or change hardware such as the hard drive, the processor or the motherboard, that activation can't be used again, and our warranty doesn't cover it.

In practice: plan which 5 computers you will activate before you start, and use a computer that will keep its current hardware and installation. An activation used on a computer that you format later doesn't come back.

5. 5PC, single licenses or MAK?

• One computer: Windows 11 Professional, the RETAIL License for 1 PC.
• Up to 5 computers, managed together: Windows 11 Professional 5PC. One key to keep, one purchase and one invoice.
• Many computers in a company: a volume license such as Windows 11 Professional MAK. Read What Is a MAK Volume License? and MAK vs KMS vs RETAIL Licenses to compare.

6. Office 2021 Professional Plus 5PC works the same way

We sell one more 5PC product: Office 2021 Professional Plus 5PC, also a RETAIL License, for Windows only. One key activates 5 PCs, and each activation is entered inside Office. The difference: it can also be activated with a Confirmation ID through Microsoft's activation portal, and we guide you step by step.

Before you buy it, keep in mind that Office 2021 is no longer updated by Microsoft: support ended on October 13, 2026. The product page shows that date in its License details tab.

7. Warranty, the 24 hours and refunds

These rules are ours, not Microsoft's, and they are the same on our license types page:

• 24 hours to activate: from the moment you reveal a license, you have 24 hours to activate it or, if it doesn't work, to tell us. If a license doesn't work, tell us within 24 hours of revealing it and we will replace it right away.
• Warranty: lifetime, when you activate it within 24 hours of revealing it: for as long as you use it on the device where you activated it.
• Refunds: within 30 days of your purchase, as long as you haven't revealed it.

So reveal your key when your computers are ready to be activated. Our checklist before you reveal helps you get ready. Full details: Warranty.

What this post doesn't cover: activating Windows 11 Home Single Language, and moving an activation to a different computer, which a RETAIL activation doesn't allow.
