Question about windows 11 product key for activating Windows 11 os

Built a new PC and already installed Windows 11 Home on this computer. However, advanced settings are not available as this copy is not activated. It is also very annoying to see the activation watermark on the desktop. 

The problem is that the price is so high for buying a Windows 11 product key from Microsoft website. I can't afford it currently. Is there any other way to get a Windows 11 product key so I can activate Windows 11 to make changes to the system settings.

Thank you

    As far as I know, there are a few apps available that let you activate Windows 11 without a product key.

    The primary concern is the expense if you want to get a Windows 11 product key, as official Windows licenses can be costly, especially for some users. Some licenses are tied to the original hardware or user account, limiting transferability. Purchasing keys from unofficial or third-party sellers can be risky; counterfeit or invalid keys may not activate or could cause system issues. While not directly related to the key, ensure your hardware meets Windows 11 requirements for optimal performance.

    While buying a genuine Windows 11 product key ensures full functionality and support, it involves an expense. If budget is a concern, the methods you mentioned for upgrading from Windows 10 or continuing with unactivated Windows remain options, but they come with limitations like the activation watermark and restricted personalization.

    You can activate Windows 11 free using a valid Windows 10 product key because Microsoft allows free upgrades for compatible systems. Here's how to do it without buying Windows 11 product key:

    Method 1: During Windows 11 Installation

    1. Install Windows 11 (via USB or ISO).
    2. When prompted for a product key, click "I don’t have a product key" (you can skip this step).
    3. After installation, go to Settings > System > Activation.
    4. Click "Change product key" and enter your Windows 10 key.
    5. If it’s a digital license (previously linked to your Microsoft account), it should activate automatically.

    Method 2: After Installation (If Not Activated)

    Open Settings (Win + I) → System → Activation.

    Click "Change product key" and enter your Windows 10 key to activate Windows 11 for free.

    If it doesn’t work, try:

    Troubleshooting: Click "Troubleshoot" and sign in to your Microsoft account (if your license is linked).

    Phone Activation: If online activation fails, call Microsoft support for manual activation.

    Important Notes:

    ✅ Works if:

    Your Windows 10 key is retail (not OEM, unless reinstalling on the same PC).

    Your hardware hasn’t changed significantly.

    ❌ Won’t work if:

    The key is from an Enterprise/Volume License.

    It’s an OEM key from a different PC.

    The key has been blocked or used too many times.

    2. Security Risks: Unofficial keys often come from sources that may distribute malware, viruses, or other malicious software that can compromise your system's security and personal data.

    3. System Stability: Activated with unofficial or invalid keys, Windows may not function correctly, leading to instability, bugs, or limited functionality.
