The Windows command processor (cmd.exe) with high memory usage may cause system performance to decline and even system crashes. This article will explore the causes of this problem and possible solutions.

High memory usage Windows command processor

Windows command processor (cmd.exe) is mainly used to perform various tasks, and usually does not occupy an exceptional large amount of memory resources during runtime. If you encounter CMD's high memory usage, it usually means that the computer may be infected with malware, there may be problems with the system settings, or an abnormal background process interferes with cmd.exe.

When cmd.exe takes up a lot of memory, the computer may run slowly, and even encounter a blue screen of death or a black screen. Therefore, measures need to be taken to reduce the memory usage of Windows command processors. Here are some useful solutions.

How to fix the problem that Windows command processors occupy a lot of RAM

Method 1: Run a virus scan

Some malware may masquerade as a cmd.exe process to perform malicious activities and lead to high memory usage. In this case, you can use Windows Defender to perform a full virus or malware scan, which will scan system files, programs, temporary files, and more. Once threats are detected, Windows Defender will quarantine or delete them.

Step 1: Press Windows I to open the settings.

Step 2: Navigate to Update and Security > Windows Security > Virus and Threat Protection.

Step 3: Click Scan option .

Step 4: Select Full Scan or other preferred scanning method, and then click Scan Now .

If you uninstall Windows Defender, you can also run a virus scan using other third-party antivirus software installed on your computer.

Method 2: Disable unnecessary startup files

Sometimes, cmd.exe's high memory footprint is caused by certain startup items, especially if you use certain automation scripts or task scheduling tools. In this case, you need to disable all unnecessary startup items and check if the problem is resolved.

First, right-click the Windows logo button and open Task Manager.

Secondly, go to Start tab, select the enabled unnecessary programs, and click Disable . Repeat this process to disable all target items.

Method 3: Perform SFC scan

Corrupt or missing system files can also be the culprit for the high memory usage of Windows command processors. You can use the SFC command to verify that there are corrupt system files and repair or replace them.

1. Enter in the Windows search box. When the command prompt option appears, right-click it and select Run as administrator.
If the User Account Control window appears, select
2. Yes to continue.
Enter
3. sfc /scannow and press Enter.

Method 4: Reinstall Windows

Reinstalling Windows can help completely remove potential malware, replace system files, and delete suspicious programs. However, this requires you to reconfigure the system, install the application, recover files, etc. Therefore, unless all the above methods are invalid, it is not recommended to perform a system reinstallation.

A fresh installation of the system will delete all personal files and applications. Therefore, be sure to back up files and applications before reinstalling Windows.

Download Windows Media Creation Tool and use it to create a Windows installation USB media.
Enter into the BIOS and select the USB drive as the preferred boot option.
Boot from the USB drive and start the installation process. After the installation is complete and the operating system is set up, you can restore the backup files to the new system.

Method 5: End the task at each startup

Each task manually ending a Windows command processor that consumes a lot of memory from the Task Manager is not the most thorough solution. However, if the above method doesn't work for you, or you don't want to spend time and effort reinstalling the system, then this is also a temporary executable solution.

Summary

If the Windows Command Processor's high memory usage is caused by a malware infection, it can be fixed by performing a virus scan. In addition, disabling unnecessary startup items, repairing system files, and reinstalling Windows are all effective ways to solve this problem.
