How do I get a windows 11 activation key free or at cheap price?

Windows 11 product key is not cheap if you purchased is from Microsoft. In fact, you can activate Windows 11 free using a Windows 10 product key.

Method 1: Free Upgrade from Windows 10 to Windows 11

If your PC meets the Windows 11 system requirements, you can upgrade directly from Windows 10 to Windows 11 for free while keeping your existing license.

Your Windows 10 digital license will automatically convert to a Windows 11 license after upgrading.

Method 2. Clean Install of Windows 11 Using a Windows 10 Key

If you perform a clean installation (via USB or ISO), you can enter your Windows 10 product key during setup (or after installation in Settings > Activation).

Microsoft still accepts Windows 7, 8, and 10 keys for Windows 11 activation, as long as they’re genuine and unused on another device. So you don't need to get a Windows 11 activation key if the current OS is activated.

Exceptions Where It May Not Work

OEM Keys (Pre-installed on a PC): If your Windows 10 license was tied to a specific motherboard (common with laptops), you may need to reinstall Windows 10 first, then upgrade.

Volume License/Enterprise Keys: These require a business agreement and won’t work for Home/Pro retail activations.

Blocked/Banned Keys: If the key was previously used illegally, Microsoft may reject it.
