QuickTime 7.7.9 improves security and is recommended for all QuickTime 7 users on Windows

2009 年之後的新版 Windows 已支援 H.264 和 AAC 等 QuickTime 7 啟用的主要媒體格式。 所有現行 Windows 網頁瀏覽器都可支援影片，而不需要瀏覽器外掛模組。

QuickTime 7 播放程式支援廣泛的產業標準音訊格式，包括 AIFF、WAV、MOV、MP4（僅 AAC）、CAF 與 AAC/ADTS。 蘋果將 QuickTime 架構設計成強大、可延展與彈性的平台以建立數位媒體，在新版本進入市場時仍維持與之前版本的向後相容性。

Apple no longer supports the QuickTime 7 program for Windows. All versions of Windows OS have support for basic media formats, such as H. 264 and AAC, for which QuickTime 7 software was necessary to work with.
