    Does Windows run processes in the background that don't show usage?


    I have to do a lot of tech support for the company I work for and one of the most common problems we have is that computers (mostly Dell OptiPlex machines, all Windows 10, usually 8th Gen Intel with minimum 8GB RAM and platter drives) run slow for no apparent reason. For example, today I was looking at a machine that showed roughly 20% CPU usage yet the CPU was turboing to 3.8GHz, memory utilization of roughly 50%, and disk usage that shot up and down from 100% to almost nothing. This machine was excruciatingly slow. I disabled the SysMain process and that seemed to help a little bit, but at some point the computer just randomly decided it was time to be cooperative, snappy, and responsive. I checked the resource utilization and nothing really significant had changed, obviously there were no more bumps up to 100% disk usage but that metric was entirely random throughout the troubleshooting process.

    Is it possible that Windows or 3rd party applications can hide their resource utilization from task manager and resource monitor? That's the only thing I can think of to explain what's going on.

    Hello @CursedLemon,

    Have a look at these? . . .

    > Process Monitor
    > Process Network Monitor

    I hope this helps.

    This does look to be more in-depth than either Task Manager or Resource Monitor. Next time I'm dealing with an episode of slowness I'll give this a shot.
