Windows 10: High CPU Usage from Explorer.exe
High CPU Usage from Explorer.exe
My explorer.exe consistently uses 25%~ of my CPU, it persists through restarts and restarting the process itself. I believe a reinstall would fix it but i'd much rather fix it manually first if I can.
Please ask for any more information you may need.
Welcome to the forums, find out the page file size, if it's system managed, try increasing the size, follow the steps from 3 to 9 in this tutorial:Virtual Memory Paging File - Change
Hi, thanks for your reply brummyfan, sorry I'm taking so long to get back, I had completely forgotten I made the thread. I believe I have done what you asked, but I haven't seen any noticeable difference, even after rebooting.
Have you tried running an sfc/scannow to see if you have corrupt files? You need to run it from the command prompt as administrator.Let it run and let us know what the results say. It will take about 10 min.
If there is corruption its any easy fix if the sfc doesn't fix it,
I believe I ran that a few weeks ago when I first noticed the problem, but I just ran it again to make sure. It said no integrity violations.
Hmmm... And you tried restarting it from within the task manager?
Have you tried running a scan with Malwarebytes and your AV, possible you may be infected. Try the scans, and later try booting into safe mode and see if it persists...another possibility is that a rouge program is causing it. Let us know
Just found this
1) Open C:Windows/Temp
2) Delete all the data
3) Open task manager
4) Terminate explorer.exe
5) Start a new explorer.exe
6) Problem solved.
Alright, so I also found your Solved section before, I tried that then, and now.
I then did a scan with MWB, which picked up a few files but nothing it deemed dangerous. I ran a full scan on my AV instead of a quick scan, and it picked up 3 Severe, which it hadn't before. I removed those and then booted into safe mode.
The High CPU usage was there, but was remedied when I did the solved steps again safe mode. Explorer.exe then remain low CPU usage (<1%) until I rebooted normally. The problem was still there out of safe mode and was not fixed by repeated the steps again.
Seems like you have a deep root virus, you may have to do a clean reinstall , unless we find a way to totally flush out the infection...some are bitch to get rid of, and it would be less time consuming to just clean reinstall. I assume you have a clean backup of your files lying around? Maybe a system image prior to the problem?
Check online for other virus removals, others pick up some that are left behind from your AV or MWB. I'll sleep on it.
Also try running MWB in safe mode and AV also.
I probably sound like an idiot, but is it easy to get a fresh install of win10, it was the free upgrade and i'm not sure what the process would be.
Get a free copy of Macrium Reflect, create a recovery CD, backup the whole hard drive to an external HDD, clean install.
I recently upgraded both my PC to Windows 10, and whenever I copy large amount of files (or analyzing large amount of files before copying), with explorer.exe uses a massive amount of CPU (~50%) and memory (~up to 3 GB). System process also uses a...

Hello everyone. I used win 7 before win 10 and now I have an issue with memory. For instance, playing games like nba2k15 my computer used about 2.6-2.8 GB of 4 GB but not more than 3 GB in win 7. Now it uses almost all 4 GB and of course it lags....
