Actually with one form of a trojan that causes this that's not true, or atleast wasn't in my case, this trojan known as surfsidekick. Even after being manually removed from the registry etc. it has edited into windows somewhere (where I don't know) to cause LimeWire.exe to re-open itself. After I removed this trojan from my pc all the problems stopped, I could use cmd.exe once again etc. But LimeWire still continually opened. Thus I resorted to this quick fix. As of now there is nothing running in the background that is abnormal and my cpu usage is at a steady 0-3% with no spikes whatsoever. This may not be the case for winupdates, but for surfsidekick it is. But I appreciate the assistance and will look into Norbie just in case, can never be too safe anyhow. Thanks.
