Opening a folder containing a large number of AVI file can open quite slowly because the OS has to open each AVI file and extract info from AVIs. If you have a large collection, you can speedup XP’s folder access to blocking it from automatically extracting this info. Doesn’t hurt anything, the OS will read the info if you open the AVI.
Rename the key by placing a minus in front of the keyname to enhance file system speed when working with AVIs : change HKEY_CLASSES_ROOTCLSID{87D62D94-71B3-4b9a-9489-5FE6850DC73E} to -{87D62D94-71B3-4b9a-9489-5FE6850DC73E}
