For Windows users who want to uninstall QuickTime, Apple has published a support documenthttps://support.apple.com/en-us/HT205771 that outlines all of the necessary steps. QuickTime for Mac is not affected.

The retirement of QuickTime for Windows has been in the planning stages for at least a few months. Apple has not yet supported QuickTime for Windows 8 or 10, although some users found ways to work around the restriction. The January update removed the browser plugin for QuickTime, making it impossible for video on websites to seamlessly play in a user's browser. As a result, there's little chance QuickTime vulnerabilities could be harnessed into a drive-by download exploit. Instead, exploits would have to rely on social engineering that convinces a user to download a video and open it in QuickTime.

For those wondering, iTunes and QuickTime were separated out a couple of years ago and iTunes no longer requires QuickTime to run properly.
