Hello CharlieRJ,
Thank you for your post.
From the post, I understand that the problem to be: There is a high CPU
utilization of Explorer.exe in the System process. If I have misunderstood
your concern, please let me know.
As for this high CPU utilization issue, we generally need to analyze the
performance monitor logs and memory dump files to locate the root cause.
Unfortunately, debugging is beyond what we can do in the newsgroups because
of the nature of newsgroup support. A support call to our product service
team is needed for the debugging service. I'd like to recommend that you
contact Microsoft Customer Support Service (CSS) for assistance so that
this problem can be resolved efficiently. To obtain the phone numbers for
specific technology request please take a look at the web site listed below:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;PHONENUMBERS
If you are outside the US please see:
http://support.microsoft.com for regional support phone numbers.
Having said that, I'd still like to provide the following general
troubleshooting steps to see if we can eliminate this problem:
Note: Please perform a complete system backup first. If any unexpected
issue occurs, we can quickly restore the system to the current status.
A. Scan your system to make sure that the system is virus free. Temporarily
disable your anti-virus software to see if this problem is gone.
You may need to upgrade your anti-virus software as Forty-nine mentioned
and some other worm or Trojan horse specific anti-virus tools to scan your
system.
B. If you have recently installed any software, hardware or drivers, please
remove them.
C. Disable all the third party startup programs and services by using the
MSConfig.exe utility shipped with Windows Vista. To use this tool, you can
refer to the following Microsoft Knowledge Base article:
How to perform a clean boot procedure to prevent background programs from
interfering with a game or a program that you currently use:
http://support.microsoft.com/kb/331796/en-us
1) Run MSCONFIG.EXE.
2) In the Services tab, click "Hide All Microsoft Services" and click
"Disable All".
3) In the Startup tab, click "Disable All". Click OK. (This will
temporarily prevent third-party programs from running automatically during
start-up.)
4) Restart the computer and keep monitoring it. Does the problem still
persist?
If the problem does not occur, it indicates that the problem is related to
one application or service we have disabled. You may use the MSCONFIG tool
again to re-enable the disabled item one by one to find out the culprit.
However, if the issue still persists, please contact Microsoft Customer
Support Service (CSS) for further troubleshooting. I hope the problem will
be resolved soon. Thanks!
Sincerely,
George Yin
