How to Fix High RAM Usage (STEPS)

Why is my RAM usage too high?

Your RAM usage is too high because there could be too many programs running simultaneously, insufficient disk space ora  registry hack.


  • Too many programs running at the same time sufficient disk space
  • Defective program design
  • Antivirus
  • Registry hack
  • Numerous background programs running from Startup


Some other causes for high RAM usage include antivirus, registry hack, and too many background programs running from Startup.


Too many programs running at the same time

If too many programs are running, you need to close them and work only on the ones you require to lower the RAM usage.


Insufficient disk space

If your system runs out of disk space, it resorts to an activity known as paging to disk. This transfers some of the system’s physical memory (content) to the hard disk. Your system uses the hard drive space for virtual memory. 


Defective program design

A defective software design causes a memory leak. This impacts the system server where programs run consistently. It impacts the RAM until the downtime of the system.



All antivirus and anti-malware software requires a large amount of RAM for your system to run smoothly.


Registry hack

When you make changes to the registry in your computer, it gets saved in a file. In case you need to run a reinstallation on your system or a new machine, you have a backup on the registry. This results in high RAM usage.


Numerous programs running from Startup 

Numerous background programs start running when you switch on your computer resulting in high usage of RAM.


High RAM usage


Why is my RAM usage so high in Windows 10?

Your RAM usage is so high in Windows 10 because of a flawed program design, registry hack, or several background programs running on start-up. Less disk space and multiple programs running simultaneously can cause the problem.

The following steps help to resolve these issues.


Flawed program design

A flawed program design causes a memory leak. Memory leaks in Windows tend to consume a lot of RAM. This can be resolved as follows:

  1. Download a software patch. This works as a quick-fix job for a programming device that is designed to solve all functional issues.
  2. Opt for a change in the version of Windows. 
  3. Uninstall any faulty software.


Set registry hack

This enables deletion of Page File when you switch OFFyour machine and helps release virtual memory. 

  1. Press Windows + keys.
  2. Type Regedit. This opens the Registry editor.
  3. Navigate to HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Control>Session Manager>Memory Management.
  4. Find the Clear Page File At Shut Down option and right-click on it.
  5. Modify its value to 1.
  6. Click on OK to save the change.
  7. Restart your computer to boot with the registry hack setting.


Numerous background programs running from Startup

  1. Press the Ctrl+Alt+Del keys.
  2. Select the Task Manager option.

How do I fix high RAM usage?

You can fix high RAM usage by disabling all the Startup programs and closing other apps and programs that keep running in the background. You can also increase the virtual and the physical memory and defragment the hard drive.


How to fix high RAM usage?

You can fix high RAM usage by tracking your memory and cleaning up the processes, disabling Startup programs that are not required, and stopping background apps from running.

You can resolve these issues in the following way.

Is 85% RAM usage too high?

85% RAM usage is not too high if your workload is demanding. On the other hand, if you are not working with very heavy data files and your RAM usage is 85%, it’s a sign that some rogue application is using up your memory.

You should access the Task Manager on your computer to understand what is causing so much memory usage. If the program is not necessary, you can disable it. 


Is RAM usage supposed to be high?

RAM usage is supposed to be high if you are working consistently on heavy data files. If your computer has a very small amount of RAM installed, then the usage can be 80% even when the machine is idle.


Is 90% RAM usage good?

A 90% usage of RAM is ok if you are involved in working with some heavy data (files and graphics). If your computer has 2GB RAM, then you should upgrade the memory to at least 3GB. If it shows 90% usage all the time even when you are not working with heavy files, you should click the Processes tab in Task Manager and click on Memory.

 If any programs are not required, you can right-click on them and disable them. You can delete suspicious programs immediately.


What happens if RAM usage is 100%?

If RAM usage is 100%, your computer slows down considerably. As the usage is high, the device will resort to using your hard disk as a temporary memory store. This is called swap memory. Hard disks are known for being slower than the system memory. In extreme cases of RAM usage being 100%, the machine can crash.


Can high RAM usage damage your computer?

High RAM usage does not damage your computer. If you do a pagefile operation, it may crash Windows. Your machine may have innumerable internal processes, most of which you may not require. You can disable them to reduce the RAM usage.


Is unused RAM wasted RAM?

The operating system of your computer manages all the applications and programs. When files are not being used, the OS keeps them in the RAM until they are required. So, the more the amount of RAM, even if you don’t require it, the less the hurdle of having to buy new RAM.


Why is my RAM usage so high when nothing is running?

Your RAM usage is high even though nothing is running because of the Superfetch service that loads your frequently used programs and files into the RAM cache. This RAM is set free when required somewhere else on your machine. 


You can remove unwanted programs, check for malware, and cleanup the disks.

You can resolve this issue with the following steps.


Remove unwanted programs

  1. In the search bar, type Control Panel.
  2. Under Programs, click on Uninstall a program.
  3. Select the program you wish to uninstall and right-click on it.
  4. Click Uninstall.


Check for Malware

If you have enabled Windows Defender on your computer, it will quarantine the threat.

  1. Type Virus & threat protection in the search bar.
  2. Click on Taking action on threats.
  3. In Protection history, check the status of the threat.
  4. Open the Task Manager window and check for extra programs which you are not using.
  5. Right-click on each program one by one and click End task.


Clean the disks

  • In the search menu, typeCreate a restore point. This opens a new pop-up window.
  • Name this restore point with a date and some context for easy reference in the future.
  • Once it is created, select the drive and right-click on it.
  • Click Properties.
  • Click the General tab and click on Disk Cleanup. You will be presented with a list of the files which can be removed (temporary internet files etc.)

  • Select the files you want to delete and click on OK.
  • Click the Tools tab.
  • In the Optimize and defragment drive section, click the Optimize button.


What is considered high memory usage?

High memory usage is a state where the RAM, ROM, and even the cache usage in a Windows computer is of a very high level. High memory usage can range between 70% and 99% of your machine’s memory. High memory usage occurs due to many internal processes running at the same time.
