Which version of Windows does NOT typically utilize NTFS for file system structure during a clean installation?

Windows XP is the version that does not typically utilize NTFS for file system structure during a clean installation by default. While Windows XP does support NTFS, it originally shipped with the FAT32 file system as the default option for installations. In contrast, Windows 7, Windows 10, and Windows 8 all default to NTFS, which provides better security, reliability, and support for larger files compared to FAT32.

This distinction is important in understanding the evolution of file systems in Windows operating systems, where NTFS became the standard primarily due to its advanced features, including file permissions, encryption, and journaling, which enhance the overall performance and stability in later versions compared to the older FAT32 system often associated with Windows XP installations.
