100 percent CPU usage caused by SVCHOST process, need help

by Lee Koo (ADMIN) ModeratorCNET staff - 4/17/09 2:24 PM

Question:

Hi, I am most frustrated by a process that takes the CPU to 100 percent use and then lets it drop back to about 50 percent every couple of seconds, which seems to run while my Vista 32BIT computer is idle with no programs actually running other than Windows. The usage report shows the offending "thing" to be "svchost," whatever that is-but it can hog up to 78 percent of the CPU, making everything else run like it was an old 286! Can you please tell me what this process is? Is it something I can disable? How I can fix this very frustrating problem! Thank you.
