Now my PC has a clean install and its still unusable because of this problem.

One thing i will add is that when i pull the Network cable the issue goes away, so its defiantly updating something but i cant see it being windows updates as it keeps failing from which i assume is because of this Services usage.ĭoes anyone know what this could be as its driving me nuts, I did a clean install as my PC was becoming unusable. as to the other possible problems i doubt they would affect a high end machine. Yes my machine has updates to run but its having a hard time installing them because of this SVCHOST usage. I running I7 5960x so its not anything to do with the machine spec, i have done the normal googling for the issue and found various articles ranging from Windows Updates, Spotlight, P2P delivery.

But I just clean installed W10 1607 on my Home machine and ive got it on this too. First time i saw this happen i assumed it was because the machines i was installing on were low end. If there is not very many documents and/or the folder size is not that large it does not do it. Ive installed Win 10 both builds 1511 & now 1607, after the clean install i always see Service Host: Local System use almost 100% CPU usage. I have a laptop (Windows 10 Home) that when I open a folder or network drive the explorer.exe CPU usage stays around 60 and the overall CPU stays around 70, fans start spinning faster and desktop icons blink.
