I just started having this problem with the CPU going to 100% usage about a month ago and poked around the internet for solutions. I was as happy as anyone when Microsoft announced the recent security update that touted a fix for the Windows XP resource-hog problem associated with the system's SVCHOST.EXE processes. Only... applying the fix didn't work for me.
Here's the hardware: Dell Vostro 1510 Intel Core2 Duo CPU with 3GB RAM
Here's the operating system: Microsoft Windows XP Professional Version 2002 SP3
Here's what I've done to solve the problem thus far:
- Turned off Automatic Updates
- Scanned for viruses with McAfee Total Protection Service version 5.0.0 Patch 5
- Ran Full Scan with Malwarebytes Anti-Malware 18.104.22.1680
- Ran Piriform CCleaner v4.09.4471
- Reinstalled Internet Explorer 8
- Based on the bulletin MS13-097/KB 2898785 Windows XP SP3 Internet Explorer 8 I downloaded and manually applied the Cumulative Security Update for Internet Explorer Windows (dated Jan. 14, 2014 - XP-KB2914368-x86-ENU.exe)
- Physically disconnected from the network (and thus the internet) by disabling the Wireless Network Connection
My biggest surprise was that last one -- I thought surely it will stop seeking updates and pegging my CPU at 100% usage when it realizes there is no internet connection. Nope.
I'm really at a loss for what to do next. After reading so many success stories after this latest update from Microsoft was released, I thought my problem would finally be solved.
Is there any other trick I should be trying to fix this issue once and for all?
