Problem: svchost.exe file take up 100% of cpu resources (when Internet is turned on)

One possible cause of high loads from svchost is the DNS Client service. On some cases, it can cause high CPU loads. So, if you are facing this problem and dont need Windows DNS Client service you can disable it.

How to stop/disable the DNS Client
Type "services.msc" on the run box, find "DNS Client" and on the proprieties, chance it to "Disabled". If you are running a firewall, you can also disable Windows Firewall to, if you are using other there is no reason to keep both because can provoke conflicts.

After it, everything should back normal.
