    CPU goes up to 40-50% until I open up task manager.


    I recently reinstalled windows to have a fresh start, and up until today everything has been going smoothly. Today when I when I opened up task manager I noticed my cpu utilization was at 30-50% and immediately jumped down to 1-5%. This has happened to me before after installing a cryptominer unknowingly, but I haven't installed anything from a sketchy website sense I reinstalled windows. This has only started happening today, and the only differences between today and a few days ago is:

    I updated my computer to 1909.

    I installed LiveSplit, OBS Studio, and SLOBS Streamlabs OBS.


    Because I am almost certain I didn't install a virus, and because OBS and LiveSplit haven't cause issues in the past, I am assuming that it's because I updated windows.


    I know people have had this issue before, and I've tried the solutions that I could find, but none of them worked. Most people ended up having a virus, and unless steam games and a bunch of widely used software have viruses in them, I don't think I have a virus. If it is because I updated windows, is there a fix for it, or am I just going to have to live with it until a patch comes out.


    Thanks,

    William

    Groove Music taking 50-60% of CPU in task manager


    As the title says, while playing music the Groove Music in task manager is taking up 50-60% of my CPU. I doubt it is supposed to be this much does anyone have any suggestions?

    CPU at 100% that goes away when opening Task Manager

    Thanks for your answer @Jay#222. I understand that a computer is doing a lot in the background. In that case above, I was using Adobe Lightroom which is heavy on the CPU but I might get this when I'm just using Google Chrome googling things. Its weird to
    me because upon opening the Task Manager, my CPU calms down when it might have been working hard for quite some time. My CPU might be working hard for 10 minutes and then upon opening Task Manager, it calms down. I'm sure if it listed the CPU usage prior to
    opening the Task Manager, it would be 90%-100% usage all prior. Is it something like the Task Manager flushes processes and that's why it drop significantly? And I mean it drops to the point where the fan will calm down and my laptop will not lag much.

    CPU goes up to 40-50% until I open up task manager.

    High CPU Usage from Task Manager, Then CPU Usage Goes Down Very Fast

    I am noticing that whenever I open task manager the Task Manager process is using 15 - 20% of CPU, but then it quickly goes down to less then 1% CPU Usage.

    Also my fans randomly speed up, and whenever I open task manager the CPU Usage of task manager goes down and the fans start to slow down, but when I close task manager the fans start back up again.
