It was recently announced that Quicktime for Windows has a couple ugly security holes. Apple subsequently announced that Quicktime for Windows is no longer supported so it would not be patched. Since Quicktime is no longer required for iTunes (which is likely where it was installed from on your computer) and modern programs and browsers can handle Quicktime-type files natively, we highly recommend you remove Quicktime for Windows. Here’s how you do it.

Note: If you use any video editing products, particularly some versions of Adobe Premier, make sure that your software doesn’t require Quicktime before removing this software.

1. Open the Start menu in Windows.
2. Using the search field, search for “Add or Remove Programs” to open up the proper control panel.
3. Scroll down and click on “QuickTime.”
4. Click on “Uninstall” and then follow the prompts to remove the software.
5. Reboot your computer, just to make sure everything is gone.

If you don’t see QuickTime listed, you’re good to go and not affected by this issue (assuming you don’t install QuickTime again).

You can do some more advanced clean up should the mood strike, but the above steps should be sufficient.

Do note that QuickTime for Mac is still fully supported by Apple, so you don’t need to remove the software if you’re running a Mac.
