Which Windows version introduced the Quick Launch toolbar?

Which Windows version introduced the Quick Launch toolbar? The correct answer is Windows 95.

The Quick Launch toolbar was introduced through Microsoft's Windows Desktop Update, which was distributed with Internet Explorer 4. This update modified the Windows shell and added Quick Launch alongside features such as Active Desktop.

The update was available for Windows 95 and Windows NT 4.0. Among the answer choices, Windows 95 is the canonical version associated with the feature's introduction.

Later releases bundled or incorporated the feature more directly. Windows 95 OSR 2.5 included Quick Launch, and Windows 98 also contained it. That later availability does not change which listed Windows version introduced the toolbar.
