Windows 10 Disk at 100% with No Programs Running

If you’re experiencing unusually high disk usage on your Windows 10 PC even when no programs are running, you’re not alone.

Check for malware or viruses using an antivirus program and remove any threats that are detected.

Solutions for High Disk Usage on Windows 10

If you are experiencing high disk usage on your Windows 10 computer with no visible programs running, there are solutions to help alleviate the issue.

First, open the Task Manager by pressing Ctrl + Shift + Esc and check which programs or processes are using the most resources. If there are any non-essential programs running, end their tasks.

If the issue persists, disable SuperFetch by searching for “Services” in the Start menu, finding SuperFetch in the list, and selecting “Stop” from the menu options.

Additionally, check for malware or viruses with an antivirus software.

If the high disk usage continues, it may be due to a lack of hard disk space. Consider removing any unnecessary files or upgrading to a larger hard drive.

Disabling SuperFetch to Reduce Disk Usage

Disabling SuperFetch is a simple solution for reducing disk usage in Windows 10. To do this, press the Windows key and R at the same time to open the Run dialog box. Type “services.msc” and press Enter. Find “SuperFetch” in the list of services and right-click it. Select “Properties” and change the “Startup type” to “Disabled”. Click “Apply” and then “OK”.

This will stop SuperFetch from running in the background and using up valuable resources on your hard drive. You should notice a decrease in CPU and memory usage, as well as a reduction in percent disk utilization. This is particularly helpful if you are experiencing high disk usage with no programs running, which can be a common issue in Windows 10.

By disabling SuperFetch, you can free up more hard disk space and improve the overall performance of your computer. This is especially important if you use resource-intensive programs like Google Chrome or are planning to upgrade to Windows 11.

Updating Device Drivers for Optimal Disk Performance

To update device drivers for optimal disk performance in Windows 10, follow these steps.

1. Open the Device Manager by typing “Device Manager” in the Windows search bar.

2. Expand the “Disk drives” category and right-click on your hard drive.

3. Select “Update driver” and choose “Search automatically for updated driver software”.

4. If a new driver is found, follow the prompts to install it.

5. Repeat this process for any other devices that may impact disk performance, such as your CPU or memory.

6. Consider disabling any unnecessary programs or services that may be causing high CPU or disk utilization, such as Google Chrome or Windows 11 usage.

By updating your device drivers and managing your system resources, you can improve your disk performance and reduce the likelihood of 100% disk usage.

import psutil

def check_disk_usage():
disk_usage = psutil.disk_usage('/')
if disk_usage.percent == 100 and len(psutil.process_iter()) == 0:
print("Disk usage is at 100% with no active programs running.")
print("Disk usage is normal.")


This code uses the `psutil` library to monitor disk usage and active processes. The `disk_usage()` function returns the disk usage as a named tuple, which includes the percentage of disk usage. The `process_iter()` function returns an iterator for all currently running processes.

The `check_disk_usage()` function checks if the disk usage is at 100% and if there are no active processes running. If both conditions are met, it prints a message indicating that the disk usage is at 100% with no active programs running. Otherwise, it prints a message indicating that the disk usage is normal.

Note that this is just a sample code and you may need to modify it to fit your specific needs. Additionally, it is important to exercise caution when monitoring disk usage and avoid running any code that may cause harm to your device.

Checking for Corrupted System Files to Improve Disk Usage

To check for corrupted system files that may be causing high disk utilization on Windows 10, follow these steps:

1. Press the Windows key + X on your keyboard and select “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.
2. Type “sfc /scannow” and press Enter.
3. Wait for the scan to finish. This may take some time.
4. If any corrupted files are found, they will be automatically repaired by the system.
5. Restart your computer and check if the disk usage has improved.

This process checks for any corrupted system files that may be causing high disk utilization. By repairing these files, you may be able to improve the performance of your computer and reduce its resource usage.

Remember to regularly monitor your disk, CPU, and memory usage to ensure your computer is running smoothly.

Resetting Virtual Memory to Fix High Disk Usage

If you’re experiencing high disk usage on Windows 10, resetting virtual memory might help.
To do this, go to the Start menu and type “advanced system settings” in the search bar.
Click on “View advanced system settings” and then select the “Settings” button under the “Performance” section.
Next, go to the “Advanced” tab and click on “Change” under the “Virtual memory” section.
Uncheck the box that says “Automatically manage paging file size for all drives” and select the “Custom size” option.
Enter the recommended initial and maximum sizes, which can be found by multiplying your RAM size by 1.5.
Finally, click “Set” and then “OK” to apply the changes.
This should reset your virtual memory and help reduce high disk usage.
