    To resolve the issue with your Windows installation being locked and requiring a product key, you have a few options:

    1. Contact the Seller: Since you purchased the computer second-hand, reach out to the seller and ask if they can provide the original product key for Windows Professional.
    2. Check for a COA: Look for a Certificate of Authenticity (COA) sticker on the computer. This sticker often contains the product key for the Windows version installed.
    3. Use a Key Finder Tool: If you can boot into the existing Windows installation, you might use third-party software to retrieve the product key from the system registry.
    4. Purchase a New License: If you cannot obtain the original key, consider purchasing a new Windows license for either Windows Professional or Windows Home, depending on your preference.
    5. Reinstall Windows: If you decide to switch to Windows Home, you will need to perform a clean installation. You can download the Windows installation media from Microsoft and follow the instructions to install it. Note that this will require a new product key for Windows Home.

    If you need further assistance, feel free to ask!
