Tip: Uninstall QuickTime for Windows

It would seem that QuickTime for Windows is no longer being supported by Apple and presents a potential security risk. iTunes hasn't relied on QuickTime for several versions and in most cases you are unlikely to have content or visit websites where it is needed. Ideally you should uninstall QuickTime without delay. See Uninstall QuickTime 7 for Windows - Apple Support for removal advice.

See Troubleshooting issues with iTunes for Windows updates if you have any problems uninstalling QuickTime or updating iTunes. Note that in some cases Apple Software Update may have stopped providing you the latest builds. At the time of posting the current builds of iTunes are 12.3.3.17 for Windows 7 or later and 12.1.3.6 for Windows XP & Vista.
