    Alright dudes,

    Just wondering if anyone has come across this old problem before? problem is the apparent "fix" does not work for me?

    The problem arises when I try and access .AVI files from windows explorer, my system pretty much crashes and explorer.exe will run my CPU at 100% until I force it to close or reboot.

    The microsoft fix is allegedly included in XP SP2. I have XP pro and SP2 and still have problem. I have also tried the registry editing which appears to be the correct fix that is widely available on the web. Deleting this pair seems to work for most?

    HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler
    3. Delete "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"

    HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{87D62D94-71B3-4b9a-9489-5FE6850DC73E}\InProcServer32

    Nothing works for me, anyone any ideas?

    I use VLC player normally, but I dont have to open the file, just going to the folder they are stored in is enough, soon as my mouse hovers over a file it happens.

    could be a combination of explorer thumbnail view and missing avi decoders (divx, xvid, etc.). so i guess my question is, do you have thumbnail view enabled in your windows explorer, and are the avi files specifically encoded?

    [edit] it already happens when hovering over the file? hmmm. can you go into folder options > view > advanced settings, and disable the option show pop-up description for folder and desktop items, and tell us if this changes anything?

    I've had this problem before and d-Faktor is right. You may also find that you can't delete the file because explorer is trying to make the thumbnail still.

    If that happens, restart you machine using a win98 startup disk Bootdisk and delete it when in DOS.

    It worked for me anyway :biggrin

    Thanks for all the input,

    I tried everything recommended here but nothing seems to work.
    I can easily delete the files at any time, never had this message saying file is in use, problem is I want to view most of these files, unsure if there is specific encoding on them. They do actually work and I can watch them but after that I need to force explorer.exe to shut down and then restart it to free up my CPU. Of all the stuff I tried the registry editing makes most sense but doesnt work for me, and I dont know why? :x

    Does this happen on all players or just isolated to the one VLC?

    all players, if I use windows media player it hogs about 75% CPU and explorer the other 25%. with others it's just explorer that goes 100%

    a. Try turning off folder synchronisation on C: if configured as it can affect to use of certain media files like .avi files on auto preview in my experience. [this is simple..]
    or
    b. Try using the actual Divx encoder to play .avi files, after first uninstalling you current encoder, and see if that is an improvement.
    or [still probable]
    c. see if it can auto preview the file using an administrative account, ie if it does not reinstalll nad start the app as an administrator - rather like what happens to Outlook when you first set it up on a pc..

    did you just delete the {87D62D94-71B3-4b9a-9489-5FE6850DC73E} part from the data field, or did you delete the default string altogether?

    Hi,
    I first deleted just the data but when that never worked I deleted the entire string.

    if you go to c:\windows\, or c:\winnt\, there should be a clock.avi. do you have the same problem with that file?

    I have this problem always and sometimes reboot helps.
    First time was caused by a virus/trojan, second time
    was cos of a dumb program i installed.
