Windows 7: SVCHost Consuming 100% CPU

SVCHost Consuming 100% CPU

My PC has started running very slowly and I have narrowed this down to SVCHost running at 100% cpu in the task manager. Using Process Explorer I can see that this process is hosting Power, PlugnPlay and DCOMLaunch services.

I have run several anti-virus applications including malwarebytes and nothing was found.

How do I solve this?

You should probably looking at Plug and Play devices you have plugged into your machine.

Whilst I find that hard to believe, given most hardware nowadays is PnP detected (during boot, so you don't see it), but if you don't have anything attached to a USB or other bus on the machine at the moment then you may still be correct that it's not the issue. However, it is rarely seen that power causes issues, so that's why logic pointed out PnP as the easiest place to start looking.

A few questions to help us help you better - namely, when did this start (if you can remember), and with that question in mind what changed on the system before that time (patches, software updates, hardware changes, etc)? Given the very narrow nature of that svchost, the more you can provide us the more we can help pinpoint the issue.

You can very quickly break it down to which process with this small application (no install necessary)
