Following news from Trend Micro that QuickTime for Windows has two new serious security vulnerabilities, Apple has decided to end support for the plugin and player on Windows entirely. Apple justifies the move by claiming that essentially nothing uses QuickTime anymore—not even the company's own iTunes for Windows—and it also says HTML5 video playback is common and well-supported these days.
While Apple's stance isn't an alarmist one, security researchers are taking a much more urgent tone. Trend Micro and the United States Computer Emergency Readiness Team advise all users to uninstall QuickTime immediately, since the vulnerabilities will not be patched. If you're left without a video player after this tragic loss, might we suggest mpv?
