Windows 10: sudden High CPU usage

I've recently started experiencing extreme cpu usage numbers when doing basic tasks. It idles at around 150-20% yet ramps up to 60-100% when I so much as do anything in a program (e.g. switch browser tabs, open new browser tab, click on a task manager process) or start one. Especially in my games, I've had massive performance drops (much lower frame rates, much higher cpu usage) and the general pc feels very slow and unresponsive (takes a second to open start menu, takes 5 seconds to open task manager).

I've run a windows memory diagnostics tool which hasn't been able to detect any issues and I've run an Intel diagnostics software which also hasn't found anything. This leaves me with either broken hardware (motherboard) or a software problem.

The only thing I've seen out of the norm (except of course the slowness, high cpu usage) was this error message in the windows logs:


(The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID

{2593F8B9-4EAF-457C-B68A-50F6B8EA6B54}

and APPID

{15C20B67-12E7-4BB6-92BB-7AFF07997402}

to the user -----\------- ------ SID (S-1-5-21-3745887014-3654249968-306677812-1001) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.


Is there anything else I can do/try or that could be an issue? Cpu is intel core i7 8700.

high cpu usage

After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
programs and find no viruses. Any suggestions? Thanks.

 

Windows 10 High CPU usage Fix

Hi i'm writing here to post an answer to the Windows 10 High CPU issue that i found and also ask the Microsoft Team why does this occur so i can understand it.

So to the answer; my CPU usage all of the sudden became high over the last few weeks, i'd tried to trouble shoot as others and Microsoft had suggested, though nothing worked. Microsoft has suggested to create a new account and transfer files which also proved
fruitless after transferring files as explorer.exe again consumed high CPU usage. It was just luck that i stumbled across the solution in one of these threads that linked to an answer from 2011.

Firstly i just want to state that i did download process explorer and it had revealed it was explorer.exe causing high CPU usage and not a .dll file.

The solution:

Broken icons on desktop. That's it. After reading The Solution i found i had 3 desktop files with no
icons at all. I deleted these three files (two shortcuts, one PDF) and instantly the CPU usage by explorer.exe dropped from a constant 38-40% down to 0.2%

I was wondering if someone or Microsoft might be able to clarify what causes this to actually happen?

Thank you

 

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.
