Microsoft Office 2021 Professional for Windows – Single PC Licence
This is an online activation licence for Office 2021 Professional on one Windows PC. It installs Word, Excel, PowerPoint, Outlook, Access, Publisher and Teams, activates directly against Microsoft's servers, and never expires. The key arrives by email within minutes of your order clearing.
Who This Licence Suits
Choose this version if you want a permanent Office install on a single machine and you are happy to activate through the desktop application rather than a Microsoft account. It is the simplest route for a personal laptop, a home office desktop or a single workstation that will not be replaced soon.
- One-time payment – no subscription and no renewal
- Full desktop suite, not a web or trial edition
- 32-bit and 64-bit installers, all language packs included
- Key and written activation guide emailed almost instantly
- Replacement key issued if your licence fails to activate
Activation Steps
- Complete checkout and open the email containing your key.
- Download the official Office 2021 Pro Plus installer from Microsoft.
- Install, then launch Word or Excel.
- Enter your key at the activation prompt – activation completes online in seconds.
Licence Limitations
- Cannot be transferred to a second device once activated
- Not a bind key – it will not appear in your Microsoft account
- Windows only; it will not install on macOS
- Activate within 30 days of purchase
