Windows 10 Pro Key (5 PCs)

What you get

After payment you receive one 25-character Windows 10 Pro product key by email, and that key activates Windows 10 Pro on five PCs. Delivery is instant in most cases (a system delay can occasionally add 5–10 minutes). The email includes the link to Microsoft’s official download and our step-by-step activation guide, and the key is also saved under My Account → Keys.

Windows 10 support: what you should know

Microsoft ended support for Windows 10 on 14 October 2025. Windows 10 Pro still installs, activates and runs, but it no longer gets free security updates. Businesses can pay Microsoft for up to three years of Extended Security Updates (ESU).

This key suits offices with older PCs that can’t run Windows 11, or with software that only runs on Windows 10. For PCs that meet the Windows 11 requirements, choose Windows 11 Pro (5 PCs).

What Windows 10 Pro adds over Home

• BitLocker drive encryption
• Remote Desktop, to connect to office PCs from home or another device
• Hyper-V virtual machines and Windows Sandbox
• Group Policy and joining a company domain, for managing several PCs
• Windows Update for Business, to control when updates install

License and activation

This is a retail Windows 10 Pro key with five activations. Each activation is online and one-time, and it stays with the PC it was used on: you can reinstall Windows 10 on that PC as long as its hardware doesn’t change, but you can’t move an activation to a different computer.

The key activates Windows 10 Pro in 32-bit or 64-bit. It doesn’t activate Windows 11.

Is it genuine? Why is it cheaper than Microsoft’s price?

Yes. It’s a genuine Microsoft key that activates on Microsoft’s own servers. We buy unused licenses from companies that purchase Microsoft products in large batches, at a fraction of the retail price, and pass the saving on.

The key you receive is exactly the one described here: one retail Windows 10 Pro key for five PCs, activated online.

How to activate on each PC

1. On each computer, open Settings > Update & Security > Activation.
2. Select Change product key and enter the same 25-character key.
3. Windows activates online. A PC running Windows 10 Home upgrades to Pro and restarts; its files and apps stay.

For a clean installation, create a USB stick with Microsoft’s Media Creation Tool, install Windows 10 Pro on each PC and enter the key during setup or afterwards in Settings.

Tip: keep a list of the PCs you’ve activated, so you always know how many activations you have left.

If activation fails

• “This product key didn’t work”: check that the PC runs Windows 10 (not Windows 11) and that you typed the key exactly as in the email.
• A sixth PC: the key covers five PCs. For more computers, order another key.
• Anything else: contact us within 15 days of your order, on live chat or at support@cheapkeys.io. We’ll fix it or replace the key, and if no working solution is possible, you get a refund under our refund policy.
