CPU running at 100% constantly

  ronec1 16:49 08 Jan 2017

My wife's Windows 7 laptop is very slow. Task Manager shows CPU at 100%. There is very little software installed and some Toshiba bloatware has been removed. I have scanned for virus and malware using Malwarebytes and Superantispyware. I have checked the services and svhost is 98%on the CPU column. Attached is a screen print of what is highlighted in Services. Any ideas how to get it back to normal?

......and svhost is 98%on the CPU column.

Before you can think about how to fix the problem you'll need to identify the specific service that's causing your CPU all that bother. Here's how:

In Task Manager's "Performance" section, click on the button to launch the Resource Monitor. When that opens, click the CPU tab, identify the culprit that's using all the CPU cycles (svchost) then tick it. Look in the lower panes of that window for the name of the sub-process that's over-active. You'll probably find what you're looking for in the "Services" pane.

Thanks secret squirreel. When I find it do I just 'end the process' or try and find why it is causing the problem

...do I just 'end the process' .......

Oooh er - don't do that because you could crash Windows :(

When you find the specific culprit let me know its name and I'll advise further. I'm guessing it's the Windows Update service that's causing your problems but I want to be sure first.

Okay, I have just fired the laptop up again. All seemed okay for a few minutes the the svchost.exe(netsvcs) has gone to 98%

Think I might have sorted it, with a download that checks the Microsoft Updates, for faults. I said it found something and fixed it, so we will see what happens in a couple of days.
