Re: 99-100% Explorer Processor Usage

Thanks.

Looking at screenshots when the reported problem occurs, the
application runs as a single separate process whose CPU usage and
memory consumption is normal. The abnormality lies on the separate
explorer.exe process which consumes 99-100% CPU.

Query: Using this tool, in a Treeview format view and the listing off
explorer.exe, how can one know exactly which application is making
Windows Explorer misbehave?

You need to find the specific process in that custom app that's taking all
the CPU resources.
Try Process Explorer:

Hi,
Have a problem where computers running a custom application are
experiencing machine freezes with Explorer.exe running at 99-100% CPU
usage for extended periods.This renders the custom application
unusable.

The workaround is to kill the explorer.exe process or reboot the
machine. This incidents seem to be of a random nature and occur on
multiple PCs. The OS's on this PCs are Win2K and WinXP SP2.

Following is a list of findings so far as to the possible causes of
this problem. None of them seems to have eliminated the incidents I'm
reporting:-

1. Hardware device or undetected hardware problems e.g. USB devices
2. Presence of a virus which takes on the form of explorer

3. Bugs with anti-virus programme updates like OfficeScan/TrendMicro
e.g. Ref:

4. Presence of a corrupt AVI file on the server or client PC(s)

5. A bug with Microsoft products where Explorer.exe uses 100 Percent of
the CPU When You Right-Click an Item in Windows Explorer.

6. A bug with Microsoft products where Windows Stops Responding When
You Click a Large AVI File in Windows Explorer.
Ref:
http://support.microsoft.com/default.aspx?scid=kb;en-us;822430&Product=winxp

Is there anyone else who has experienced their Windows Explorer running
at 99-100% CPU usage? If so, what measure(s) were successfully
undertaken to address this?

As I look deeper into this issue, I'd appreciate any further
information based on your experiences with this issue.

Thank you.
