How to Buy Windows 11 Product Key from Microsoft
Buying a Windows 11 product key from Microsoft gives you a real license for the operating system.
A Windows 11 product key is a 25-character code. This code proves your copy of Windows 11 is legit and lets you use all its features.
Getting your key straight from Microsoft means you’re getting an official one. This helps prevent problems like Windows not activating or features not working, especially when you first set up Windows 11 or change your computer’s parts.
Buy a Windows 11 product key directly from the Microsoft Store website. Select either Windows 11 Home or Pro, complete the purchase, and Microsoft will provide you with a 25-character alphanumeric code to activate your operating system. This ensures you receive an authentic and legitimate license.
What happens when you are done?
Once you’re done purchasing and entering your Windows 11 product key, your PC will be fully activated, granting you access to all features and updates.
Retail vs. OEM: What is the difference?
When you buy a Windows 11 product key, you’ll encounter two main types: Retail and OEM. (OEM, or Original Equipment Manufacturer, keys are typically tied to the hardware they’re installed on.)
Are cheap keys from third-party sites safe?
Cheap Windows 11 product keys purchased from websites other than Microsoft carry risks. These keys may be unauthorized by Microsoft, meaning they are not legitimate. Such keys could stop working at any time, leaving you without a valid Windows 11 license, which is required for full functionality.
How to check if your Windows is already activated
Before you buy a Windows 11 product key, check if your PC is already activated. You can do this by looking in Settings or using Command Prompt.

Summary
In summary, buying a genuine Windows 11 product key directly from Microsoft offers the most secure way to activate your PC, helping you avoid problems associated with cheaper keys from other vendors.
Can I transfer a 🪟 Windows 11 product key to a new PC?
Yes, if you purchased a Retail license, you can transfer it to a new computer by deactivating it on the old one. However, OEM licenses are permanently tied to the original hardware and cannot be transferred to a different device. Always check your license type before attempting a transfer.
Do I need a product key if I am upgrading from 🪟 Windows 10?
If you are upgrading a genuine, activated copy of Windows 10 to Windows 11, you generally do not need to buy a new product key. The system will automatically use your existing digital license to activate Windows 11 during the upgrade process via the Windows 11 Setup Assistant.
What is the difference between a product key and a digital license?
A product key is a 25-character code used to activate Windows. A digital license is a Windows 11 activation method that bypasses the need for a physical key. Instead, your activation status is tied to your Microsoft account and hardware setup, recorded on Microsoft’s servers.
