Since installing WindowsXP I've experienced intermitant problems where explorer.exe would be stuck consuming 100% CPU time -- the only way to remedy the problem is to reboot (or quit the process). I have no idea what is causing this probme to occur (i.e. there is no discernable pattern I could recognize).

Anyone else experience this problem?

Hmm, I guess I should have looked at the latest messages posted before I posted my own. But yes, I am experiencing the same problems. When I first boot the computer, explorer runs really slow. If I endtask it and restart it, everything is good to go. Explorer wont slow down again unless of course I restart the comp. If i dont end task it, explorer eventually crashes, sends in an error report, and then restarts. Everything is fine after that.

i have seen this also, but i'm really not sure what is causing it. i open up the task manager and added the VM Size column and it looks as if explorer uses up more virtual memory than it does physical memory. does anyone know a reason for this? does this mean that explorer has a memory leak in it, and that causes it to crash or to slow down? right now my VM Size on explorer is about 2000 K larger than the Memory Usage. Thanks to anyone who knows what is going on.

i haven't had that problem yet, but then again, the system w/ xp on it has 512mb of ram. but the computer is a p2-450mhz. i know that isn't the fastest system to put xp on but it works well, it was a bit slow but i took that as a sign of the cpu processing capability. not sure how else to explain it.
does anyone know of a microsoft link that talks about this? or customer complaints on it and how ms is dealing w/ it?

I've had similar troubles. Explorer.exe would start to eat extreme amounts of CPU time, and attempting to close it is hopeless. The only solution that works for me is to close all programs and hit that power button. All my other programs are fairly well behaved. I had similar troubles when I had RC2, and my system is fairly fast (AMD 950, 512MB)

It certainly appears that this is a "real" problem.

I recently observed that this 100% CPU hogging sometimes occurs when I try to quit an application. The application refuses to quit (the process just doesn't want to die) -- and explorer.exe goes nuts and jumps up to 100% CPU usage.

I've observed this several times quiting Word2000 and even cancelling a print process. I can't seem to find any discernable pattern to the phenomina. No idea why it's happening.

As a lab monitor, I'm having this problem daily. All PCs in my lab are new, P4 1.3Ghz, 512MB; but they crash everyday due to IExplorer. Hope that MS will fix this problem soon!

Check out this page from tweakxp.com. It looks like the explorer cpu at 100% could relate to some corrupt temp internet files. I am not sure exactly how this relates and I have not been able to test this since so far my problem has disappeared.

Your link refers to "Internet Explorer". This problem concerns "explorer.exe". Explorer controls the drawing of all windows and folders.

internet explorer and windows explorer very closely relate. Its worth a shot. I may have also failed to mention that I have also noticed this problem when initially running internet explorer. Just a suggestion that could possibly help resolve the issue. Oh yeah, explorer.exe would be at 100%cpu when ie6 was running. I also recently (today) ran a windows update that had a critical fix with ide drives released within the last month. Here's a little more info to add from an event log.

Faulting application explorer.exe, version 6.0.2600.0, faulting module wininet.dll, version 6.0.2712.300, fault address 0x0000648f.

I know that some of the old Windows screensavers take up a massive amount of CPU time.
Also, using some windows 95 programs (some still work) tend to slow the processor down for some strange reason. I know that on my Dell, explorer.exe sometimes gets bogged down.

Have you run Windows Update recently? There have been a nice amount of updates for XP which may help with the problem.

Do you have system restore enabled? It may be trying to create a restore point.

I've had similiar problems in 2k before, but then it was because I had some many windows up doing a project that it ticked off my computer. Maybe you're running so much stuff at once your processor can't handle it? Have you scanned your hard drive(s) for viruses lately? I had one a few days ago that was eating up resources that Norton just finally contained.

Try going through the Windows Explorer settings and make it a SEPARATE PROCESS.

The 100% pegging can occur when the DESKTOP is trying to render a lot of information, but WinExplorer is equally trying to process folder and drive stuff.

Having them being separate processes, more RAM can be allocated to each process, reducing the likelihood of sporatic 100% CPU when you're doing anything requiring intensive rendering (DirectX-specific or otherwise).

I had this same problem until I did the activation after 30 days, since then, I've never had a problem. That, along with several other quirky issues seemed to be resolved after the activation. Not sure if it was the fix, but that was the event sequence...

nasser how would you go about making windows explorer a seperate process? do you use the task manager or what? i tried looking for what you were talking about and can't find anything that you are talking about. please explain this a little better please.

Maybe Nasser is talking about if you go into folder options, under the view tab in the advanced section there is a check box that says launch folder windows in a seperate process.

I have a fairly new pc, it's a month and a half old.

I have the same problem, i have only noticed it recently. It slows my p4 2.66 with 512 DRR ram right down. The tweakXP solution seams viable, unless it's a virus, and i'm gonna install Norton soon because of this problem.

Explorer.exe takes 100% cpu usage while the idle process should be running at max (i'm not doing anything on my pc), the fix for me is to end the process and then run explorer.exe from windows directory, bit of a pain but it works. Maybe it doesn't crash my PC because it's a little faster than the older ones ? just gives it a real hard time ?

well i'm gonna try the tweakXp solution, if it dont work i'll get back to you.

Noel
