QuickTime for Windows has a couple glaring security holes that won’t be patched. If you’re using the program, uninstall it as soon as you can.
Trend Micro found two critical vulnerabilities in the video player and released a call to action Thursday saying users should get rid of it. Normally when a program has these kinds of security issues, the company that developed it ships out a fix (or a patch) in the form of an update (note: this is why keeping your tech updated is so important). But in this case, Apple has said it won’t be supporting QuickTime for Windows any longer. So, these security issues aren’t going to be patched.
If you’re on a Mac computer, you’re OK to keep using QuickTime.
Here’s how to uninstall the Windows program:
Go to your PC’s control panel. You can usually get there via the start menu. 
Inside your control panel, click programs and then programs and features. Some machines may reveal shortcuts within the control panel to uninstall or change a program — clicking that will work, too.
Once you’re in the right place, all you have to do is select the program you want to remove and click uninstall.
