Disable Quicktime plugin for Internet Explorer

Question

There has been discussion on a number of forums regarding the Quicktime plugin for Windows Internet Explorer and how it will hijack file associations, preventing them from being opened up with your default application. This only occurs when clicking on a link on a website. This even occurs when the file assocations in Windows are set to open a particular media file with your desired player. Disabling the Quicking plugin in the Internet Explorer settings may only makes things worse because instead of the file playing with the Quicktime plugin, Internet Explorer displays a red "X", and doesn't play the media. Uninstalling Quicktime is a solution, but if you, like me, own a Apple device and use iTunes, Quicktime must be installed. There are a number of postings on the web with potential solutions, but none of them worked for me.
After troubleshooting for some time, I have finally figured out how to disable the plugin once and for all. I have narrowed it down to the registry entry that apparently loads the plugin into Internet Explorer. By simply deleting this entry, the Quicktime plugin will no longer load with IE and media will be launched with your favorite player. You can easily revert back to the Quicktime plugin by restoring the registry entry from a backup. Below, I have provided the reg.exe command line commands to backup and delete the registry entry.
1) Close out of Internet Explorer.
2)Backup with this command:
reg export "HKLM\SOFTWARE\Classes\Wow6432Node\CLSID\{4063BE15-3B08-470D-A0D5-B37161CFFD69} " C:\qt_plugin1.reg
NOTE: This registry path is for Windows x64 (64-bit). I am not certain of the path for Windows x86 (32-bit), but I assume you may just need to remove Wow6432Node from the path. If it is not there, open regedit.exe and search for 4063BE15-3B08-470D-A0D5-B37161CFFD69.
3) Delete with this command:
reg delete "HKLM\SOFTWARE\Classes\Wow6432Node\CLSID\{4063BE15-3B08-470D-A0D5-B37161CFFD69} " /f
4) Open Internet Explorer and test. When you click on a music or video link, your default media player should now launch.
I have tested this myself several times, including a reinstallation of Quicktime, and it worked. If it doesn't work for some reason, you can try performing the same steps with the following registry entries. Do one at a time and test so that you don't delete anything unnecessary.
HKLM\SOFTWARE\Classes\Wow6432Node\CLSID\{CB927D12-4FF7-4A9E-A169-56E4B8A75598}
HKLM\SOFTWARE\Classes\Wow6432Node\CLSID\{02BF25D5-8C17-4B23-BC80-D3488ABDDC6B}
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Compo nents\3F9E7EA97A1AEE54490637032025DEF9
If you wish to restore the Quicktime plugin, simply double-click the registry file that you backed up in step 2. Click yes when it asks you to confirm. Now when you open Internet Explorer and click on a link, the Quicktime plugin will load and play the media.
