98-349 · Question #350
Your friend asks for your help with upgrading his computer to Windows 10. You plan to perform a clean install of Windows 10 on his computer, which has Windows 8.1 installed. What should you tell…
The correct answer is D. Windows 10 installation files. A clean installation of Windows 10 overwrites the previous operating system and user data, leaving only the newly installed Windows 10 files and, if not manually removed, installation remnants like a "Windows.old" folder which contains the previous OS files.

Why each option
A clean installation of Windows 10 overwrites the previous operating system and user data, leaving only the newly installed Windows 10 files and, if not manually removed, installation remnants like a "Windows.old" folder which contains the previous OS files.
A clean installation typically formats the drive or overwrites the previous OS, effectively removing the functional Windows 8.1 installation. While a "Windows.old" folder might be created containing some old OS files, the *installation* itself is not retained as a functional entity.
A clean installation does not automatically create a backup copy of all personal files; users must manually back up their data *before* performing a clean install.
User profiles are not automatically migrated during a clean installation; they are part of the data that needs to be backed up and restored manually.
After a clean install, the computer's hard drive will contain the files related to the new Windows 10 installation. If the installation process was performed by booting from installation media and selecting a drive to install Windows 10, the previous OS might be moved to a "Windows.old" folder, but the primary content will be the Windows 10 files.
