    cpu usage at 100%

    CPU usage at 100% from start up for no apparently good reason. Service Host appears to be the problem but I cant narrow it down more than that at present.

    Any suggestions?

    I am using Windows 10 full release version 64 bit.

    Anniversary Update: Windows 10 CPU usage 100% All the time


    So I disabled Defender and search indexing completely.

    I did a clean boot minus TeamViewer because I have to use it to access my PC for now.
