    Shell Infrastructure Host using ~50% of CPU in Windows 10


    For over a day now, the Shell Infrastructure Host service is using around 50% of my CPU - causing the fan on my laptop to run constantly. I am running Windows 10 Professional on a Thinkpad T460P with an Intel i5-6440 CPU, 16 GB of RAM and a Samsung 1 TB SSD. I have confirmed that there are no pending Windows updates for my system KB5008212 was successfully installed on 12/17/21 and I ran a full scan with Norton Antivirus again last night, with no problems identified.

    Windows defender blocking Shell Infrastructure host

    Hi Glenn Taylor (glenn),

    Thank you for posting your question in the Microsoft Community.

    Shell Infrastructure Host is a core Windows component. Sihost.exe runs the Shell Infrastructure Host. This is critical Windows component and should not be removed. The Windows Shell Infrastructure Host is tasked with handling several
    graphical elements of the Operating System interface including taskbar transparency and Start menu.
    It’s safe to allow.

    I suggest you to follow this article to
    Allow a blocked app in Windows Security    , and check if that helps.

    Regards,

    Shell infrastructure host has stopped working

    I have tried all the methods suggested but still it does not work. Every time I start up my laptop. The screen is just black for about 15 minutes then the dialogue box will appear and says " The shell infrastructure host has stopped working." This happen
    since I upgrade my windows from 7 to 10. What will I do to make my computer open fast and to get rid of that shell infrastructure host thing?
