    Windows Explorer takes up 40-50% CPU usage


    Hello,
    I have this problem where after some hours of use (~3, for example) the windows explorer takes up 40-50% of the CPU causing major performance loss. I do not know what is causing this problem, as it does have to do with my activity, since when this happens I am not using the explorer in the means of opening a file or moving data.

    Any help would be appreciated.
    If you need further information, I will be happy to provide it.

    :)

    SkypeHost.exe usage high CPU

    Am using Windows 10 OS. I noticed that SkypeHost.exe is using too much CPU. When I attempt to stop or suspend process it restarts automatically and uses CPU up to 20-30%. How can I stop it?

    Path: "C:\Program Files\WindowsApps\Microsoft.Messaging_2.12.15004.0_x86__8wekyb3d8bbwe\SkypeHost.exe"

    Priority: Below Normal

    Memory usage: up to 60MB

    Threads: 40-50

    Windows Explorer takes up 40-50% CPU usage

    I see this too after deleting a large amount of files. The explorer window hangs open at 99% but 0 bytes left. Very reproducible.

    I'm also having this problem. Mostly happens few hours after the system started and when I have navigating through explorer a lot. Restarting explorer.exe didn't work.

    I would suggest contacting Microsoft about the issue as they may have better knowledge of this bug.
