Looks like we have a workaround which works in some scenarios, but we also have a few new scenarios.

Thanks to allan.vanleeuwenORANGEMAIL for submitting the following;

There is a better workaround for this :

Go to : Control Panel/Display/Appearance Tab/Effects Button

And *disable* (uncheck) the transition effects....

Credits to my collegue Lex Croes who found this workaround!

[Editors Note]I have tested this on my systems and it worked fine. I also got Mark Luczkowski to test it, which he did on one of his systems set to use single-clicks, and it worked fine for him too. I got a couple of other notes in on this issue as well;

We have had this problem since the install of XPSP1. Our video editing suite had 90% of the XP pc's use 100% CPU - explorer.exe. The way XP handles movie files and music files seems to be the main issue.

There is a workaround.

1. Change Explorer to "use windows classic folders"

2. Go to Start/Run/Regedit and navigate to the key below and delete the default data (right pane).

For AVI's

HKEY CLASSES ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler

For MP3's

HKEY CLASSES ROOT\SystemFileAssociations\.mp3\shellex\PropertyHandler

Note: Make a backup (export) the key before editing just for precautionary measures.

That should fix it until MS release a Fix to the public. A fix is available but you have to call them.

I can get this effect if I open a directory with multimedia files and if there is one or more video that Exporer can't play because it hasn't the right codec. At this point CPU goes to 100% and the only thing to do is call the task manager and kill the Explorer.
