Windows 10: Almost a quarter of memory usage is not used by any users?

I'm not a tech guy, so I don't understand how this works:

Two users' total memory usage is 49.6%, yet it says it uses 74%.

Why would my laptop (Inspiron 5570, if that helps) use 24% of memory? Even more confusing is that the total memory usage never went above 85% before (sometime between September and December my laptop had -- and still has -- another issue, which might be related to this), but now when I open almost any game, it goes to low-to-mid-90% (with the combined user memory usage being around 60-70%). I think that my laptop is slowing down a lot because of this; on one game, I used to get 60-70 fps with certain settings on, but now it is at a steady 9-15 fps.

74% memory being used - not many processes are open, just Google Chrome with 7 tabs

100% disk usage and memory usage

Hi,

100% disk usage and memory usage can be caused by a software corruption, running application running on the background and malware or virus infection.

For us to properly isolate the issue and provide an appropriate resolution, kindly answer the questions below:

• Did the issue happen after installing the Fall Creators?
• Did you receive any error messages?
• Can you send us the screenshot of the Task Manager showing the 100% disk usage and memory usage?
• What troubleshooting steps have you done so far?

For isolation purposes, please perform a clean boot to see if the same issue will occur. Refer to this
article for more information on how to perform a clean boot
in Windows.

Looking forward to your response.

 

100% Memory usage

Hi,

Thank you for posting your query on Microsoft Community.

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:

1. Press Windows key + X, select
task manager.

2. 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.

3. 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 this helps.

You need to increase the virtual memory by making 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 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
