Windows 10: Windows 11 gives wrong disk usage

My C: drive has a folder called "Users". It occupies a storage of 17.6GB but if I go through each subfolder in that folder, they roughly add up to 2GB. I have tried the hidden files but nothing showed up there. I know that the folder not showing is "Dell" and consists of my downloads.

100% usage on disk

No problem. In the event that Norton's defaults do not resolve the disk usage, follow the guide to Perform a Clean Boot in Windows 10 to Troubleshoot Software Conflicts and see if you can determine whether a service/process is causing issues. After step 7. in Part Two, check whether the clean boot resolved the disk usage before proceeding to step 11.

 

Windows 11 NTFS file system 100% disk usage

Hello,

I recently installed Windows 11 Home alongside an Ubuntu 22.04 operating system. I have 1TB HDD and I allocated 390GiB for Windows 11. I selected NTFS file system. Unfortunately, the PC is incredible slow because of 100 percent disk usage. For example, It took (literally) 5 minutes to open a simple Microsoft Edge application.

I have tried to fix the issue using the following resources: How to Fix 100% Disk Usage in Windows 11 (12 Effective Ways) and Windows 11 100% disk usage. None of them helped: Install all Windows update, Disable SysMain service, Disable Telemetry service, Disable Windows Search, Disable Startup Apps, Disable MSI Mode, Run Disk Check (with all NTFS option), Perform a Clean Install, Defragment the Disk.

Note that: I got an 5% fragmentation on the disk. After I defragmented the disk, the disk usage was magically decreased and everything was fast. However, when I restarted the PC then the disk usage was again 100 percent. I defragmented (the 0% fragmented disk) again but it did not help. One important thing is that the disk read/write operations are couple of KiBs on the Ubuntu 22.04 system. The disk read/write operations are multiple hundreds of KiBs on the Windows 11 system.

System Information:

• Dell Inspiron 3580 x64 based laptop
  
• Processor: Intel Core i5-8265U
  
• Memory: 16GiB RAM and 2.86GiB Page file
  
• Free space: 261.86GiB
  
• Disk: ST1000LM035-1RK172
  

I wrote this question because now I feel hopeless. I am unable to resolve the disk usage problem by myself. Support is highly appreciated!

 

How to solve Windows 10 100% disk usage ???

Hi,

Thank you for posting the query on Microsoft Community.

I am sorry to know that you are facing issues with Disk Usage. Do not worry, will assist you with the issue.

You might be facing this issue due to several reasons like low virtual memory, third party software conflicts, virus threat on the computer etc.

Even though no programs or applications are running, some background services can show memory usage and disk usage. In order to check which particular program is using the memory, I would suggest you to check the Task manager. Refer to these steps:

a) Press Windows key + X, select task manager.

b) Click on the ‘processes’ tab and it will show you show you a list of programs and services running and their corresponding memory usage

and disk usage.

c) Check if any of the item listed is consuming more memory or disk usage than normal.

I suggest you to try the following steps and check if it helps.

You need to increase this virtual memory. Make it equivalent to your RAM size for the initial size and twice of the initial size in maximum size and make sure you have the same amount of free space in your hard drive in each drive.

To do this, follow the below mentioned steps:

1. Go to Control Panel (Press Windows key+ X)> All control panel items > System

2. Click on Advanced system settings

3. Under performance, click on settings

4. Go to Advanced tab

5. Under Virtual memory, click on Change

6. UN-check "Automatically manage paging file size for all drives" check box

7. Select your Windows drive (where OS is installed)

8. Click on Custom size radio button

9. Set Initial size equivalent to your RAM size in MB

10. Set Maximum size to twice of your RAM size in MB

11. Click on Set

12. Click on OK thrice

13. Restart your system.

Keep us posted if you face any issues on Windows in future. We will be glad to help you.
