Uninstall QuickTime for Windows: Apple will not patch its security bugs (theregister.co.uk)

They should trigger an alert if it's possible within the software. I have something called "Apple Software Update" on my PC, it could be used to display an alert or even ask the user to remove Quicktime automatically...

This is a major issue for media production. Many toolchains depend on Quicktime. Premiere and AfterEffects just got a lot less useful on Windows.
