CPU usage in idle

    It doesn't matter how hefty the multi-core CPU is if the disk is busy. That's the point. The "idle detection" doesn't have a clue how busy the disk is. It's flawed. Therefore it shouldn't be used for anything important. Maybe a screen saver.

    @MilesAhead:

    I totally understood you on that point. That seems to be a poor design for sure.

    What I meant was that when the task was proceeding my thought is that MS probably doesn't account for processors that are older than 5 years. So that would explain why my PC specific reaction to the actual "scan" throttles that old 1.5Ghz P4 and draws excessive amounts of processor effort. It can't keep up.

    I gotcha'. I have to tell you when I got that crash defragging I was pretty surprised. After all, NT based Windows systems were developed by the VMS OS gurus. I woulda' thunk after all these years there'd be a call like CapacityUsed(cpu,systemdisk,time interval) or something easy. I downloaded a little fake LED disk blink thingy for the task tray and you wouldn't believe the code the dude had to use to tell how busy the disk was over the last 2 minutes. Really makes it tough on the programmer.

    hi there :)

    have you had a look at the system with these two programs from Microsoft sysinternals


    Autoruns for Windows v10.07

    introduction

    This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. These programs include ones in your startup folder, Run, RunOnce, and other Registry keys. You can configure Autoruns to show other locations, including Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond the MSConfig utility bundled with Windows Me and XP.

    Autoruns' Hide Signed Microsoft Entries option helps you to zoom in on third-party auto-starting images that have been added to your system and it has support for looking at the auto-starting images configured for other accounts configured on a system. Also included in the download package is a command-line equivalent that can output in CSV format, Autorunsc.

    You'll probably be surprised at how many executables are launched automatically!

    Process Explorer v15.03

    Introduction

    Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.

    The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

    The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
