    Hello KEVIN,

    Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.

    The Windows 10 installation .ISO file is approximately 5GB in size, and the installation requires around 25 to 30 GB of storage.

    Since you have 118GB of available storage, you can install either Windows 10 or Windows 11. However, please note that you have only 10 days to roll back from Windows 11 to Windows 10.

    If you exceed this time limit, you will need to create a Windows 10 USB installation media and use it to reinstall Windows 10, which will completely wipe all the data from your hard drive.

    I hope this information helps. If you have any questions, please let me know and I will be happy to help you further.

    Best regards,

    Gunasekar N
