Can anyone tell me why svchost.exe takes up a large
amount of cpu resources at times! What is the fundamental
behind it..... Can it be reduced. Thanx

You have a virus/worm. Search Google for svchost problems to learn about
it. Then get a good antivirus product. Then repair your system. Then
before getting online again install the antivirus.

Hi Nishant,

Svchost.exe is a generic host process name for services that are run from
dynamic-link libraries (DLLs). The Svchost.exe file is located in the
%SystemRoot%\System32 folder. At startup, Svchost.exe checks the services
portion of the registry to construct a list of services that it needs to
load. There can be multiple instances of Svchost.exe running at the same
time. Each Svchost.exe session can contain a grouping of services, so that
separate services can be run depending on how and where Svchost.exe is
started. This allows for better control and debugging.
