1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shel lex\PropertyHandler
3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"









Voila! Please not that this will no longer provide you with the windows properties displaying the AVI file information such as width, height, bitrate etc. But its a small price to pay for saving you resources.

NOTE: Please use caution when using regedit. Improper usage may cause windows to behave imcorrectly. Backup your registry first.
