Which of the following is unique to Windows XP?

Folder Options with layout controls existed across multiple Windows versions including Windows 98, Me, 2000, and XP, making it not unique to XP.

Hardware profiles were available in Windows 9x, NT, 2000, and XP, so they are not exclusive to Windows XP.

Pen and Input Devices control panel was available in Windows XP Tablet PC Edition but also appeared in later Windows versions, making it not exclusively unique to XP.

Windows XP introduced the Network Setup Wizard as a step-by-step guided tool specifically for configuring home and small office network sharing, Internet Connection Sharing, and firewall settings. This wizard was not carried forward as a standalone named feature in Windows Vista and later, which replaced it with the Network and Sharing Center. Its presence is one of the distinguishing characteristics of the Windows XP interface.
