Windows 10: High CPU usage Windows 10 and Windows 7 possible fix

I found a solution that takes a little while to perform but actually works.


From the start menu type disk clean up and open it from the search results. Select the C: drive and click ok.

It will run for a few minutes and then pop-up the files to delete window. Don't select delete instead click on find System files button, and wait for it to finish. this can take a while depending on your system. When it's done, I usually choose everything but the issue seems to be with the Windows update Cleanup, so make sure it is checked.


While disk clean up is running, I go into the Windows/Temp folder and delete it's contents and if prompted to skip or retry I skip those file that are in use. Also under the C:/ drive in file explorer you might see file folders that are random Numbers and Letters you can delete these files. You can leave them if you don't feel comfortable deleting them, most times these are empty files leftover from updates that were installed and are usually empty. They cause slow log in and reboots.


Then I go into the control panel and open configuration manger select the Cache tab. Choose the configure settings button and select the Delete Files button. Note I usually change the Amount of disk space to use to 12,000. When you select the delete files button another window appears. Check the box to include "Delete persisted cache content" and wait for it to finish deleting after you click on the delete button. Close this window.

Now open a task manager window and chose the process tab. at the bottom choose the button to show processes for all users.

Sort the process by clicking the heading of the memory usage column. By this time your disk clean up should be about done where you can delete the windows update cleanup. Now go back to the task manager and you will see Trusted installer at the top along with cleanmgr.exe Wait for them both to finish or drop down in memory usage.


Note this can take awhile I've had it take an hour for the memory to drop down from the hundred thousands. This is usually when the disk cleanup window goes away.

Now do a restart and watch as windows will run updates and reboot.

Note: This also works in Windows 10 but the process is Tiworker, instead of TrustedInstaller.

Sorry in Windows 10 task manager you want to show more details and click on the Details tab. Select the heading for Memory so higher memory use is at the top and Tiworker will show up .

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.
