My laptop is running at 100% cpu even before I load any applications. I have done the basics and done full spyware and malware scans... and disabled anything I wasnt sure of for startup in mscofig... done reboots etc and still it persists... i have downloaded sysinternals 'process explorer' and it does show a svchost.exe process 'tree' fluctuating betweem 90 and 96%. When u click the plus sign it shows wuauclt.exe and also taskeng.exe... but neither are using even 1 % of cpu according to process explorer... i tried to kill the process tree in process explorer and it gives 'error opening taskeng.exe...access is denied'... user account is a local admin<br />
&nbsp;Any views on what could be going on and how to resolve? It is windows 7 64 bit. It has a 'PID' of 824.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
