Windows 10: 100% CPU Usage

I just had a strange event. My laptop's CPU usage hit 100% and stayed there, and the fan came on even though the CPU and HD temps were normal (CPU 44-47C, HD: 39-42C). Any thoughts on what happened? Restarting seems to have fixed it, at least temporarily. I'm doing a virus scan, and I'm going to start going through the logs, but I could use some advice about which of the vast number of logs I should start with.

Edit: NOD32 and MalwareBytes both say no threats, malware, etc.

Windows 10 extreme CPU usage

Thanks, but yes I was definitely seeing this issue while that trace was recorded.

Task manager was constantly showing 100% CPU usage and Resource monitor shows silly numbers for the CPU usage (40441489%).

If I sum the numbers under CPU in the Processes tab in Resource monitor, it matches the values shown in the trace (i.e., CPU usage is not 100%, but the charts and summary total at the top of the processes tab are maxed out.

In task manager the CPU usage numbers seem to be normalised to 100%.

i.e. they are constantly changing but seem to always add up to 100%.

I think that the CPU usage reported in the trace is correct, but Task Manager and Resource monitor are doing something wrong?

 

Windows 10 FPS Low FPS in War Thunder game

Under Windows 10 I have FPS drops to around 20FPS

CPU usage First core 100% all others 18-28% * overall cpu usage 50-55%

In windows 7 all 4 cores 100-95% * overall cpu usage 95-98% 60FPS wits small dips to 59 * Preset High

MY PC spec:

X4 860k @ 4.4Ghz

8GB(2x4GB) 1866 CL9 Ram

Club 3d 7790 @ 1285/1700

Any idea how to convince Win 10 to better utilize CPU in this game ?

In other games I not have this issue example in Witcher 3 I have near to 100% overall CPU usage and decent FPS.

This issue do not exist in Windows 10 beta period.

Cheers

 

Same as what I had and this seems to fix it. I will get you the link just trying to dig it out.

 

Take an image of the machine and then try this as in an administrator cmd prompt...reboot once done.

Run the following commands, and press Enter after each command:

Net stop wuauserv

cd %systemroot%

Ren SoftwareDistribution SoftwareDistribution.old

Net start wuauserv

 

Can I store the image on the same partition as the OS? That's the only place with enough room.

 

No that is not a good idea.....external drive or a 2nd internal drive, or, a USB memory stick.

 

keep task manager running so you can see whats maxing out your cpu if it happens again , it was most likely your AV or security app going mental , they have a habit of doing that
