Can You Install and Use Windows 11 Without a Product Key? Here’s You Need to Know in 2025
In 2025, the question of whether you can install and use Windows 11 without a product key remains as relevant as ever. The short answer? Yes, you can! However, there are some important caveats to consider. While you can use Windows 11 indefinitely without activation, you’ll encounter limitations like the persistent “Activate Windows” watermark and restricted personalization options. That said, core functionalities such as updates, app installations, and gaming remain unaffected.
If you’re planning to install Windows 11 without a product key, this guide will walk you through the entire process step-by-step. Plus, we’ll explore why activation might still be worth considering. Let’s dive in!
How to Install Windows 11 Without a Product Key
The installation process can be broken down into three key stages: creating a bootable USB drive, configuring BIOS settings, and completing the installation. Here’s how to do it:
Stage 1: Create a Bootable USB Drive
Before you begin, ensure you have a USB drive with at least 8GB of free space. You’ll also need to download the official Windows 11 ISO file from Microsoft’s website. To burn the ISO to your USB drive, we recommend using Eases Partition Master, a user-friendly tool that simplifies the process.
Step-by-Step Guide:
- Launch Eases Partition Master and navigate to the Bootable Media section. Click on “Burn ISO” and then “Next.”
- Select the Windows 11 ISO file you downloaded and click “Open.”
- Choose your USB drive as the destination and click “Burn” to start the process.
Pro Tip: If you don’t have the ISO file, Eases Partition Master allows you to download a suitable Windows version directly during the process.
Stage 2: Change Boot Order in BIOS
Once your bootable USB drive is ready, you’ll need to configure your computer’s BIOS settings to prioritize booting from the USB.
Here’s How:
- Restart your computer and press the designated key (e.g., Delete, F2, F10, or Esc) to access the BIOS settings.
- Navigate to the “Boot Options” or “Boot Order” section using the arrow keys.
- Move the USB drive to the top of the boot order list.
- Save your changes and exit the BIOS. Your computer will now boot from the USB drive.
Stage 3: Install Windows 11 Without a Product Key
With your bootable USB drive and BIOS settings ready, you’re all set to install Windows 11.
Follow These Steps:
- Boot your PC from the USB drive.
- Select your preferred language, keyboard layout, and time format, then click “Next.”
- Click “Install Now” to begin the installation.
- When prompted for a product key, select “I don’t have a product key.”
- Choose the Windows 11 version you want to install and click “Next.”
- Accept the license terms and select “Custom: Install Windows Only (Advanced).”
- Choose the installation location (e.g., unallocated space or a partitioned drive) and click “Next.”
That’s it! Windows 11 will now install on your system without requiring a product key.
