How To Reduce Windows Explorer High CPU Usage
It’ѕ unfortunately common to see Windows Explorer using up your system resources. With the file explorer system hogging up proсessing power, games won’t run as smоothly, video editing will tаke longer, and other basic tasks may run into issues.
In some cases, you may see Windows Explorer using high CPU resources. Sometimes this can be up to 30% or more of your processing power, even if you have a modern processor.
Thankfully, there are fixes to this problem, but you will need to try each step out for yourself. We will list each step from how likely it is to fix your Windows Explorer high CPU problem, based on user reports online.
Remove Intel Optane Memory Pinning
It has been reported online that many people have had Intel Optane memory pinning installed to their computer in error after Windows 10 update 1903. The trouble is, most people do not have the right hardware for Intel Optane Memory Pinning, so it ends up causing Windows Explorer high CPU issues.
To find out if you have Intel Optane Memory Pinning, open the Start menu and search for Add or Remove Programs. After, follow the steps below.
- Click Add or Remove Programs in the search results.
- Search for Intel Optane Memory Pinning.

Once your PC is back on, press Ctrl+shift+esc to open Task Manager. Click on the Processes tab, and click Name to sort the processes alphabetically. If fixed, Windows Explorer should now be using very little CPU.
If Windows Explorer is still using an abnormally high CPU, move to the next step below.
Delete Desktop Icons With No Image
Many users have reported that there is a strange CPU error that occurs when there is an icon or shortcut that has no image on your desktop.
Search your desktop for any icons that aren’t displaying properly, and if so, left-click it and press the delete key on your keyboard. If it’s an important file, you can click and drag it to another folder on your PC, such as My Documents.
Switch Off OneDrive Cloud Storage
Sometimes, cloud storage can cause issues with Windows Explorer high CPU usage. By default, Windows 10 will encourage you to use OneDrive’s cloud storage and it may be turned on without you even realizing it.
Not only can this mean your files will occasionally backup, hogging your upload bandwidth, but it can also cause CPU issues.
- To switch off OneDrive cloud storage, click the taskbar at the bottom left of your screen, then right click the cloud icon.
- Once it opens, click More and then click Settings.
- Click on the Account tab and click Unlink this PC.
- Click Unlink Account.
Turn Off The ‘Show All Folders’ Option In Windows Explorer
This solution will only be for those that spot Windows Explorer high CPU usage when they actually open Windows Explorer. If this is the case, open Windows Explorer and then on the left side panel, right-click.
Next, click show all folders if there is a tick next to the option. If there isn’t a tick next to the option here, the show all folders feature will already be turned off.
If this doesn’t fix your Windows Explorer high CPU usage, try the next steps below.
Clear System Files & Temp Folder
Sometimes, clearing out your temp folder can help to reduce your Windows Explorer CPU usage.
- To get started, open the Start menu and type Disk Clean-Up.
