The easiest and safest way is to buy directly from Microsoft.

Steps:

  1. Press Windows + I to open Settings.

  2. Go to System > Activation.

  3. Under Upgrade your edition of Windows, click Open Store.

  4. The Microsoft Store will open with the Windows 11 Pro upgrade option.

  6. Your PC will automatically upgrade without reinstalling Windows.

✅ This method is perfect if you already have Windows 11 Home and just want to upgrade.

Method 2: Buy a Windows 11 Pro License Key Online

If you want a fresh installation or don’t have Windows 11 Home, you can buy a full license key.

Where to buy safely:

  • Microsoft Store (official)

  • Amazon (ensure seller is Microsoft or “sold by Amazon”)

  • Best Buy, Newegg, or other authorized retailers

💰 Average Price: $199.99 (full license)

⚠️ Avoid shady third-party websites selling keys for $10–$20. These are often:

  • Pirated or volume license keys

  • Region-locked

Method 3: Buy an OEM License with a New PC or Hardware

OEM (Original Equipment Manufacturer) licenses come pre-installed on many brand-new PCs.

  • Cheaper than retail licenses.

  • Tied to the first computer it’s installed on (non-transferable).

  • Perfect if you’re buying a new laptop or desktop.

✅ Example: Many laptops already come with Windows 11 Pro pre-installed at no extra charge.
