If you want to upgrade your desktop computer or laptop to Windows 11, the device has to have at least 4 gigabytes of random access memory (RAM).

While it is the minimum to operate Windows 11, you will need 8GB of RAM for better performance.

Upgrading the amount of memory in your computer, whether a desktop or a laptop, is the most straightforward way to make it run faster. In addition, it will significantly impact the quality of your web browsing and gaming experiences.

Is 80% RAM usage bad?

If you notice that your RAM usage is about 80% or more, you shouldn’t be concerned immediately. All the currently running software will most likely use your RAM.

For example, if you are using Google Chrome and have multiple opened tabs, your RAM usage will naturally skyrocket, and it’s not concerning.

High RAM should never be considered a problem unless no apps are opened, and the computer is experiencing this while idle; in this case, there are many reasons.

Users reported a plethora of similar issues that we will be addressing below. First, however, here are the most common ones:

  • DWM high memory usage in Windows 11 – The issue of excessive memory utilization is brought on by Desktop Window Manager for a variety of reasons; the most common of which are problems with the performance of Windows.
  • Windows Explorer high memory usage in Windows 11 – One of the most common causes is the utilization of obsolete graphics card drivers.
  • High RAM usage in Windows 11 when idle – You are opening an excessive number of applications or services; which is one of the primary causes of Windows 11’s high memory utilization.
  • High memory usage in Windows 11 when nothing is running – Put an end to pointless applications running in the background.
  • Vmmem Windows 11 high memory usage – You can terminate any applications or services that aren’t essential by using Task Manager.
  • OneDrive high memory usage in Windows 11 – To solve this problem, the most effective solution is to modify your virtual machine to prevent it from using a significant amount of the system’s resources.
  • Windows 11 memory leak – Stop using the app that’s causing the problem in order to fix the memory leak in Windows 11.

How do I fix high memory usage in Windows 11?

1. Check the RAM usage in the Task Manager

  1. To check the RAM usage in Windows 11, go to the Windows search box. Type in Task Manager and select it.
  2. Click on More Details to expand the list.processes high ram usage windows 11
  3. In the Processes tab, check the programs using too much memory.

  5. Close the Task Manager.

High RAM usage is usually caused by software acting up or glitching out. The best way to deal with this is to go into the Task Manager and terminate that task.

Keep in mind that terminating the process means turning off the program for goo, ensuringe you save any progress using it.

Additionally, since Windows 11 is still in development, you might notice that certain Windows services are taking up all the RAM space.

In that case, terminating those processes might do more harm than good since they might be crucial for the system to work correctly.

If you’re having trouble successfully terminating the processes, check out how to close Task Manager processes.

2. Disable Startup programs

  1. Click on the Windows Search Bar and select Task Manager.task-manager-w11 high ram usage windows 11
  2. In the Task Manager, go to Startup, right-click on an app, and then select Disable.startup-disable high ram usage windows 11
  3. Close the Task Manager.

Startup programs will cloud your PC and use up lots of resources. Nowadays, most of the software you install will start with your Windows.

These programs will increase your boot time, but they will also use all the processing power and RAM available when they automatically update since they constantly run in the background.

Disabling all unnecessary startup programs and only keeping those crucial to your system will keep things running optimally.

3. Disable the SysMain service

  1. Open the Windows Search Bar and type in Run.run high ram usage windows 11
  2. In the Run box, type services.msc then press Ok.services-run high ram usage windows 11

The SysMain service preloads software that you frequently use to the RAM to access quickly. First, try disabling the feature to see if it fixes the issue.

SysMain has been known to take up too much Disk and RAM usage on Windows 10, so it wouldn’t be a surprise if the same problem can be encountered in its successor.

4. Defragment your hard drive

  1. Open the Windows Search Bar, type in Defragment and Optimize Drives.defrag high ram usage windows 11
  2. Choose the drive you wish to defragment and click Optimize.

Another cause of high RAM usage and many other problems could be malware. Perhaps the issue is not even connected to Windows 11.

In this case, simply running a malware scan through the Windows Firewall is your best bet. However, keep in mind that you should always have Windows Security turned on to prevent malware.

The Windows Firewall malware database gets updated every week, but the idea of a virus breach is not out of the question.

If you tried scanning your computer and nothing bad came out, you need to use something better to eliminate the malware.

Many tools can thoroughly scan your device for the newest malware and take action against any threats, including spyware, adware, and other cyberattacks. ESET HOME Security Essential is an excellent example in that regard.

Memory cleaners are programs that scan your computer and fix any issues that they find. They do this by defragmenting your hard drive, repairing the registry, and freeing up your computer’s memory by removing unnecessary or duplicate items.

However, some memory cleaners go above and beyond this essential function. So are these 7 memory cleaner software that we have hand-picked for you to try out.

Is 40% RAM usage normal?

Any amount close to 40% of your total RAM usage is considered normal because your Windows are actively using it.

Of course, the percentage will be lower if you have a high amount of RAM. So, for example, you won’t get 40% RAM usage while idling with 32GB of total available memory.
