Are any of your company’s computers running Apple’s QuickTime for Windows? Unless you need it to play content that no other program can handle, you should seriously consider uninstalling it. Apple stopped supporting this media player/multimedia framework on the Windows platform, which means there will be no more security updates for it. (Apple is still supporting QuickTime on its OS X platform, though.) Apple designed QuickTime for Windows to run on Windows Vista and Windows 7, but it also works on later versions of Windows.

You should uninstall QuickTime for Windows sooner rather than later. In April 2016, the Zero Day Initiative released advisories about two new security vulnerabilities (ZDI-16-241 and ZDI-16-242) discovered in the application. Apple will not patch these vulnerabilities (or any others found in the future) because it no longer supports QuickTime for Windows. There are no known attacks exploiting these vulnerabilities yet. However, cybercriminals often devise and launch new attacks that specifically target unsupported software.

To uninstall QuickTime in Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10, follow these steps:

  1. Type “Control Panel” in the Windows search box.
  2. Click the “Control Panel” program listed in the search results.
  3. Make sure the Control Panel window is being displayed in the Category view. If necessary, change to that view by selecting “Category” in the “View by” drop-down list.
  4. Under Programs, click the “Uninstall a program” link.
  5. In the alphabetized list of installed programs, scroll down until you find the entry for QuickTime and then click it.
  6. A dialog box will appear asking whether you are sure that you want to uninstall QuickTime. Select “Yes”.
  7. Another dialog box might appear asking if you want to allow the QuickTime application to remove the software from your PC. If you receive this dialog box, choose “Yes”.
