Windows Explorer using 50% CPU in Win XP

I'm doing some file management and file editing using win XP and I noticed in Task Manager that explorer.exe is using approximately 50% CPU resources, even after I close the explorer window on hte desktop.

This is causing my Dell m1710 to run hot, and causes using a second cpu intensive program (video editing) to use the other 49 or 50% cpu resources to max out my cpu at 100%.

The only way to reduce the 50% cpu load on explorer.exe in task manager AFTER the window is closed on the desktop is to click on "end now" (in task manager) which then makes all my desktop icons disappear.

I can log off from task manager and then log back on and my desktop reappears. However, as soon as I reopen windows explorer, it starts using 50% of my cpu resources.

memory usage is like 34,000k, vm is like 39,000 k and base priority is "normal"

Any suggestions on what to do?

Thanks in advance!

XP is up to date with latest service packs, etc
HDD is defragged
???memtest???
anivirus was set to autoprotect, I turned off autoprotect and disabled wifi radio

Also, HDD indexing service is disabled

Thanks for the response ghn

I'm not sure if there is some "setting" somewhere that I need to enable (or disable)?

I just ran a memory test on he machine using Performance Test v4.0 andmemory allocation, cache, write, mark all passed with good numbers.

cCleaner was a HUGE help. It cleaned up more than 3.5 gb of crap on my HDD and also cleaned the registry.

I am curious about the explorer extensions. When I look in the registry, what should I be looking for???

Once again, thanks in advance!

Again, thank you for your posts!

I have also been getting an occasional error prompt as follows:

Error Deleting File or Folder
Cannot delete "file_name": It is being used by another person or program.
Close any programs that might be using the file and try again.

The "glitch" is that there are no other programs open or running besides windows explorer.exe. Explorer.exe is also showing approximately 50% cpu usage at this time as well.

I am going to download the autoruns program and see if I can benefit from that as well.

I checked my shell extensions approved folder in my registry and there are 216 values. I saved the folder info as a text file.

Here it is:

Thus far, I have been unable to correct the issue.

I did a google search and it looks like exploerer.exe using too much cpu has been a common issue with XP, Vista, and Win 7.

However, I as of yet, have still been unable to pinpoint the cause. Possibly a corrupted dll?

I am specifically working with video files between 4 gb's and 30 mb's in file size. My machine is a core 2 duo 2.16 with win xp 4 gb ram. I have run adaware, norton internet sucurity, cCleaner, defragged, but nothing has fixed this issue.

I am still getting error messageinformign me I am unable to delete certain files because they ar ein use by another person or program????

Thanks. I have tried detailed vs thumbnails but that made no difference.

I am really confused why I get the same error message (cannot delete or rename file as another person or program ia using this file) for the same file, even after rebooting windows several times in a row.

It appears there was a known issue with avi files prior to service pack 2, but I am specifically using h.264 mp4 files.

Not only is this slowing down my video rendering by decreasing the cpu resources available for that program, but it is also increasing heat build up by maxing out the cpu to 100% when I am doing something cpu intensive (rendering a video file).

I've got to figure this out as it has basically decreased the computers processing power by 50%.

Well, here's an update...

It appears I had some dll conflicts. The computer came loaded with Roxio LE and I installed Roxio creator 2009 on it. Also, my Blackberry Manager installed a Roxio "media manager" on the computer as well.

Starnge, but even after uninstalling Roxio update manager, it would "reinstall" itself after rebooting. Bizarre...

Anyway... I ended up going into regedit and deleting every entry that referred to "Roxio" AFTER I had uninstalled all of the programs associated with "Roxio."

I also uninstalled Quicktime and Realplayer and reinstalled them, then reinstalled
"just" Roxio creator 2009.

Thus far, it "seems" that the problems I was having with explorer.exe have mostly dissipated.

Thanks for the pointers, suggestions, and links for the freeware programs. They all helped "tune up" my operating system.
