Clicking AVI Files on explorer causing 100% CPU Usage

Windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file (this is displayed in the Properties window).Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesn’t contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy
memory usage.
To solve this problem all you have to do is the following:

1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler

3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"


Voila! Please note that this will no longer provide you with the windows properties displaying the AVI file information such as width, height, bitrates etc. But it’s a small price to pay for saving you resources.

NOTE: Please use caution when using regedit. Improper usage may cause windows to behave incorrectly. Also, I cannot be held responsible. Backup your registry first.
