Removing qttask.exe and preventing it loading in Windows XP

Quicktime installs a very annoying process when you install it on Windows XP called qttask.exe that you may often see running in your taskbar and processlist. There is no way to stop it running from within quicktime’s preferences. Instead, you must:

  • Go to ‘Start’ -> ‘Run’
  • Type ‘regedit’ and click ‘OK’
  • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Apple Computer, Inc.\QuickTime\ActiveX
  • Find the value QTTaskRunFlags, right click on it and change the value to 0
  • Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
    Windows\CurrentVersion\Run
  • Delete the value pointing to qttask.exe

That should stop it running automatically when you start windows or when you open Quicktime.

If you are also stuck with iTunes then see this post about removing it after you’ve installed Quicktime
