How to Install Windows 11 Without Product Key?

The Windows 11 installation process without a product key would be divided into three major steps. The first step is creating a bootable installation USB. After that, we will set the boot order in BIOS settings to make sure the PC boots from the USB drive. Lastly, we will continue with Windows 11 installation.

Stage 1. Create the Installation USB Drive

Before we begin, arrange a USB drive with at least 8GB of free space. Download the Windows 11 ISO file from the official Microsoft website and then burn Windows 11 ISO to USB using a professional tool EaseUS Partition Master.

We recommend using EaseUS Partition Master Professional for a smooth and efficient burning process. It is easy to use for beginners due to its clear interface. With simple clicks, you can burn ISO to a USB. Here is how:

Stage 2. Change Boot Order in BIOS

Once you burn Windows 11 ISO to USB and get the bootable USB drive ready, it's time to configure your computer's BIOS settings to prioritize booting from the USB drive.

Follow the steps:

Step 1. Restart your computer and immediately press the designated key to access your BIOS settings. This key may be Delete, F2, F10, Esc, or another key specific to your computer's manufacturer.

Step 2. Use the keyboard's arrow keys to navigate to the "Boot Options" or "Boot Order" section in the BIOS setup utility.

Step 3. In the "Boot Options" section, you'll see a list of drives and devices indicating the current boot order. The topmost drive is your current boot drive.

Step 4. Select the installation USB drive you created earlier and use the arrow keys to move it to the top of the boot order list, which will change your boot drive.

Step 5. Save your changes and exit the BIOS setup utility. Your computer will automatically restart and boot from the selected drive.


Now, please proceed to Stage 3 to install Windows 11 without a product key.

Activation ensures that you are using a genuine version of the operating system, complying with Microsoft's licensing terms.

🛞Avoid Annoying Notifications

Unactivated Windows 11 will constantly remind you to activate your copy, displaying an "Activate Windows" watermark on your screen.

💡Access to Microsoft Support

Only activated copies of Windows 11 are eligible for official Microsoft support.

There are three common ways to activate Windows 11:

  1. Way 1. via Activation Setup
  2. Way 2. via KMSpico
  3. Way 3. via Command Prompt

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
