Hi all. I've had a problem for a while of explorer.exe using 50% cpu, which causes my system to run slow and sluggish, even locking up some apps. I've run my spybot, and antivir, i've even formatted and the problem still occurs. I never knew what was causing it or how to stop it. Well, after a bit of research, I have narrowed it down to video files, namely, avi files. Even right clicking causes explorer.exe to shoot up to about 50% usage. Does anyone know why this is happening and how I can stop it? Thanks a bunch people!

I'm just curious. If you leave the system alone, will it eventually drop down?

I've had a problem that when you right click an AVI file, it takes minutes to display.


Sorry, I do not check for private messages

“Windows XP Explorer has a 'feature' to provide a preview in the Details box on the left of the file you have selected, if it’s supported. Image files, HTML pages, video clips, MP3s, etc are all previewed (even with the folder view open).
If you have a large movie clip and it either is corrupt (ie. no index from a partial download) or it uses an unsupported codec, then Explorer tries to load the whole file. This can slow your computer a lot and prevent deleting/renaming/moving/etc the file until it’s finished.
Simply do the following steps:
1) Open a command window (Start->Run, type in 'cmd' hit enter)
2) To remove image preview, type and hit enter regsvr32 /u shimgvw.dll
3) To readd image preview, type and hit enter regsvr32 shimgvw.dll
4) To remove media preview, type and hit enter regsvr32 /u shmedia.dll
5) To readd media preview, type and hit enter regsvr32 shmedia.dll


Thank & Regards

hi guys's. In reply to your question ham30. If I just select the file(right click), explorer.exe goes up, if I come out of the file, it will go back to normal. It's when I view or preview a file that it starts to crash. If I view or preview, explorer.exe goes up and stays there, I have to open task manager, shut it down and re-start it. Could it just be dodgy files? They are afterall from "less than attractive" p2p network. The only thing is, i never seem to have had this problem with my other computers.

It seems to have been caused by a windows media player plugin. My media player stopped responding so I closed it from task manger, as a result, media player closed down all plugins, the initial problem seems to have stopped now.
