Over time, your computer’s RAM (Random Access Memory) accumulates cached data from various processes and applications, which can lead to sluggish performance and decreased responsiveness. Clearing the RAM cache in Windows 11 is a simple yet effective way to refresh your system’s memory, improve performance, and reclaim valuable resources. In this guide, we’ll walk you through the steps to clear the RAM cache on your Windows 11 PC.

Utilize the Task Manager:

Windows 11’s Task Manager provides a straightforward method to clear the RAM cache. Here’s how:

  • Right-click on the Taskbar and select “Task Manager,” or press “Ctrl + Shift + Esc” to open it directly.
  • If Task Manager opens in its simplified view, click on “More details” to expand it.
  • Navigate to the “Processes” tab.
  • Locate the “Memory” column and click on it to sort processes by memory usage, with the highest consumers listed first.
  • Select any unnecessary processes that are consuming a significant amount of memory and click “End task” to terminate them. This action clears the associated memory cache, freeing up RAM for other applications. By terminating memory-intensive processes, you can effectively clear the RAM cache and alleviate memory pressure on your system.

Use Command Prompt (CMD):

Windows Command Prompt, or CMD, offers another method to clear the RAM cache. Follow these steps:

  • Press the “Windows + X” keys on your keyboard to open the Power User menu.
  • Select “Windows Terminal (Admin)” to open Command Prompt with administrative privileges.
  • In the Command Prompt window, type the following command: echo 1 > /proc/sys/vm/drop_caches
  • Press Enter to execute the command. This action instructs Windows to drop the cache, effectively clearing the RAM cache. It’s important to note that this method may require additional steps or modifications for certain system configurations, and it’s recommended to proceed with caution when using Command Prompt.

Restart Your PC:

Sometimes, the simplest solution is the most effective. Restarting your computer can clear the RAM cache and refresh system resources, resolving performance issues caused by excessive caching. To restart your PC in Windows 11:

  • Click on the Start menu and select the Power icon.
  • Choose “Restart” from the power options menu.
  • Wait for your computer to restart and observe any improvements in performance after the reboot.


Clearing the RAM cache in Windows 11 is a quick and effective way to optimize system performance, alleviate memory pressure, and improve responsiveness. Whether you prefer using the Task Manager, Command Prompt, or simply restarting your PC, regular maintenance of the RAM cache can help ensure smooth operation and efficient resource utilization. By following the steps outlined in this guide, you can keep your Windows 11 system running smoothly and enjoy a more responsive computing experience.
