Maximizing the RAM and CPU usage on your computer is one very effective way to speed up Windows 10. The more memory space and the remaining processor will make existing programs run smoothly, especially for those of you who are accustomed to working with multitasking, opening many applications at once.

Before we discuss further how to reduce memory usage in Windows 10, we should first understand what RAM and CPU actually are, the two components that determine the performance of a computer.

Understanding RAM and CPU and their functions of a computer

What is RAM?

RAM stands for Random Access Memory, its function as a short-term storage medium for running programs.

The more RAM available, the more programs we can run without lagging the computer.

What is a CPU?

CPU stands for Central Processing Unit. In short, the CPU is the brain of a computer whose job is to perform arithmetic operations, logic, control, and input - output (I / O) processing determined by specific instructions.

If RAM is the memory that stores program files, then the CPU is the execution of the program. These two components really determine the speed of a computer.

If only a few of them are left, the running programs will slow down, and we will no longer be able to run other programs properly. Even if it reaches 90 - 100% it can cause the computer to freeze (the screen stops, it can't be helped anymore).

To prevent this from happening in Windows 10, there are a few tips we can do.

How to reduce RAM, Disk, and CPU usage in Windows 10

1. Turn off unnecessary startup programs

Startup programs are programs that will run automatically after the computer is turned on. The more active, the greater the memory and CPU usage.

Not all programs are really needed to run at startup, we can limit them to the programs that are needed in order to reduce RAM and CPU usage.

How to turn off unnecessary startup programs:

  1. Open the Task Manager, do I right click on the Task Bar then select Task Manager.
  2. Click the Startup tab in the Task Manager.
  3. Select the program you feel is not really needed => then click the Disable button.
  4. Repeat this step until only the essential programs are left.

After turning off unnecessary startup programs, try restarting your computer. After that, check again how much RAM and CPU usage is using the Task Manager, you will definitely see the changes immediately.

2. Setting Windows 10 to "Adjust for best performance"

The second way to reduce RAM and CPU resource usage in Windows 10 is to change its display settings to best performance mode. This mode will make Windows turn off unnecessary animation effects and graphic features and optimize resources for performance.

How to Setting Windows 10 to "Adjust for best performance":

  1. Type " advanced " (without the quotes) in the search bar, then select View advanced system settings.
  2. Click on the Advanced tab.
  3. Click the Settings button in the Performance section.
  4. In the Visual Effects section, select Adjust for best performance.
  5. Click OK.

By using this mode, your Windows 10 display will feel a little changed, so it feels more flat and classic. But the advantage is there is a certain amount of memory that we can save and can be optimized to run other applications. For a PC or laptop with minimum specifications that just about doing these tips, this might be quite helpful.

3. Turn off the transparent effect

Windows 10 also has a transparent effect to make it look more beautiful. But if you pay attention to the transparent effect on Windows 10, it doesn't match the flat design theme.

I prefer to turn off this transparent effect because it is more harmonious and pleasing to the eye. The advantage is we can save a little memory resources so that computer performance is more optimal.

How to turn off transparency effects in Windows 10:

  1. Enter the Personalization menu by right clicking on an empty area on the desktop => select Personalize.
  2. Enter the Colors menu.
  3. Then drag it down to find the Transparency effects option.
  4. Click until it turns Off.

4. Increase Virtual Memory capacity

In the Windows operating system, there is also a Virtual Memory or paging file which functions to help RAM work. Files from programs that are in an idle state will be stored in this Virtual Memory.

For those who like to play games or run heavy applications, the capacity of Virtual Memory should be increased because it will be very helpful to improve performance.

5. Use the default theme

Changing the theme after installing Windows 10 does provide its own fun, you can find tons of free custom themes that can be installed. The appearance is also nice and very attractive.

But please note that installing any theme can actually be detrimental, the risk can cause the computer to be exposed to viruses and malware, problems with updates, crashes, blue screens or at least make the computer even slower.

To change the Windows 10 theme we need the Theme Patcher application which is not an official application from Microsoft, so we must be more careful in using it. Indeed, not all patches, applications and custom themes contain viruses, there are also some themes that are clean and have an attractive appearance.

But considering our goal is to reduce memory and CPU usage, this kind of hobby of changing unofficial themes should be avoided. The lightest and most performance-optimized theme for Windows 10 is the default official theme from Microsoft. With a few modifications to your color, you can still make it easy on the eyes, so there's no need to bother downloading custom themes that aren't guaranteed safety.

If you are really bored with the default theme and want to change the new nuance, then you can look for themes from the Microsoft Store. It will be much safer when compared to downloads from other unofficial sites. But I personally prefer to use the default theme because it's lighter and I don't want to cause new problems by changing themes.

6. Schedule automatic updates outside of active hours

Doing update Windows 10 is an important thing to do to maintain the performance and security of the computer remains optimal. Windows 10 has a regular update schedule that we can set the time ourselves.

The goal is that the update does not run when the computer is working, because this update process will consume a lot of resources, especially after entering the installation stage.

I have experienced several times that my computer suddenly becomes very heavy, after I check the memory and CPU usage is also very high. It turns out that the cause is the Windows update process that is running.

Even at the update installation stage, disk usage can reach 100%. This is very annoying, especially if at that time we were doing heavy work such as rendering videos or playing games because the computer becomes very slow and laggy.

To prevent this from happening, we can set a Windows automatic update schedule for the hours when we are not actively using the computer for work.

How to Schedule Automatic Update Windows 10:

  1. Click the Start button > Settings.
  2. Select the Update & Security menu.
  3. Click on Change active hours.
  4. Turn off the option Automatically adjusts active hours for this device based on activity.
  5. Click the Change menu.
  6. Determine the time span when you use your computer to work. Automatic updates will not take place at this time frame that you specify.
  7. Click on Save.

7. Kill programs manually with the task manager

When the RAM, disk and CPU usage on our computers is very high because there are too many programs running, using the Task Manager to kill unnecessary programs will be very helpful.

Sometimes even though a program has been closed but there are still processes running in the background, we can do it in the Task Manager to turn it off.

How to kill programs manually using the task manager on Windows 10:

  1. Open the Task Manager.
  2. Click on the Processes tab.
  3. Select and click the program that you think you don't need anymore.
  4. Click End task.
  5. Repeat this step until all programs are not turned off.

8. Restart the computer

The most instant way to restore low and stable resource usage is to restart the computer. When using the Task Manager is too complicated, an easier way to make RAM, disk, and CPU usage on the computer return to normal is by restarting it.

9. Uninstall bloatware and unnecessary programs

Bloatware is a term for applications that use more resources (RAM, Disk, CPU) than needed. This kind of application usually has bad management and will eat up more and more storage over time. If not removed, bloatware will also continue to run and consume high resources so that our computers become slow.

Bloatware usually has commercial purposes, which often comes with free, trial, and pirated applications. After the bloatware is installed, this program will continue to run and consume resources which we can actually use in other programs, not infrequently this application will also display notifications in the form of bids and advertisements. Anyway, it sucks, therefore we have to delete it.

How to Uninstall bloatware and unnecessary programs on Windows 10:

  1. Open the Control Panel.
  2. Select Programs and Features.
  3. Find programs that are suspected of being bloatware.
  4. Right click the program.
  5. Select Uninstall.
  6. Also uninstall programs that are no longer needed. 

If there is a program that cannot be installed, then we can use an application such as RevoUninstaller. To make sure the computer is really clean you can also take advantage of a cleaner application.

10. Clean viruses and malware

The last, no less important tip for reducing memory, CPU, and disk usage in Windows 10 is to make sure it is free of viruses and malware.

Viruses and malware are meaner than blather, if bloatware generally carries out its commercial mission in a subtle way, then viruses and malware have a more crude means.

Viruses and malware can cause a lot of problems, let's take the example of a shortcut virus that I find very often on a friend's laptop. This virus will continue to reproduce itself as long as the computer is on, thus making it very slow.

Laptops affected by shortcut viruses usually experience up to 100% disk usage when viewed from the Task Manager, other than that the original files will be hidden by the virus, making us very troublesome.

That's just one example, there are many other forms of viruses and malware that are very harmful.

How to prevent and clean it?

I would recommend you to use the default antivirus application Windows 10, namely Windows Security (formerly Windows Defender).

Over the years using Windows 10 it has proven that Windows Security is good enough to keep the PC I use free of viruses and malware. All we need to do is keep it updated and active.


  1. Click Settings.
  2. Select Update & Security.
  3. Select Windows Security.
  4. Click on the Virus & threat protection option.
  5. Perform a Full Scan.
  6. After the scan is complete, click Manage settings in the Virus & threat protection settings section.
  7. Enable Real-time protection and all the features there.
  8. Make sure all indicators in Windows Security are green. 

Don't forget to always update Windows 10 to get the latest security patches and virus databases, this way we can be more calm because Windows Security can work more optimally to protect computers from virus and malware attacks.

Those are some tips to reduce RAM, CPU, and disk memory usage in Windows 10 that I can give this opportunity.
