How to clear computer memory Windows 10?

Is your Windows 10 computer running slow or showing signs of lagging? It could be due to excessive memory usage. When your system’s memory is overloaded, it can result in decreased performance and an overall frustrating experience. However, fret not! In this article, we will discuss some effective methods to clear computer memory in Windows 10, helping you optimize your system and enhance its overall speed.

What is Computer Memory?

Computer memory, often referred to as RAM (Random Access Memory), is a crucial component in every computer system. It acts as a temporary storage unit that allows your computer to quickly access data, applications, and processes while they are in use. However, when you have too many programs running simultaneously or encounter memory leaks, your system’s memory may become overloaded, resulting in decreased performance.

How to Clear Computer Memory in Windows 10?

To clear computer memory in Windows 10 and improve system performance, follow these steps:

1. Restart your computer: One of the simplest yet effective methods to clear computer memory is to restart your system. This action closes all running processes and helps release trapped memory, giving your computer a fresh start.

2. Close unnecessary programs: Identify and close any unnecessary programs running in the background. These programs consume memory and may not be essential for your immediate use.

3. Use the Task Manager: Press Ctrl+Shift+Esc to open the Task Manager. From the Processes tab, you can identify memory-hogging applications and end them by selecting “End Task.”

4. Adjust startup programs: Open the Task Manager, go to the Startup tab, and disable unnecessary programs from launching at startup, reducing the memory load during boot-up.

5. Clear browser cache: The cache files stored in your browser consume memory over time. Clear the cache in your preferred browser to free up memory.

6. Limit background apps: In the Windows Settings, navigate to Privacy, then Background Apps, and disable unnecessary applications from running in the background.

7. Run the Disk Cleanup tool: Type “Disk Cleanup” in the Windows search bar, select the appropriate drive, and let the tool scan your system for temporary files, system files, and other unnecessary data that can be safely removed to free up memory.

8. Adjust virtual memory: Open the Control Panel, search for “Performance,” and select “Adjust the appearance and performance of Windows.” Under the “Advanced” tab, click on “Change” in the Virtual Memory section, and uncheck “Automatically manage paging file size for all drives.” Then, customize the virtual memory size based on your system’s requirements.

9. Disable visual effects: Under the same Performance options, navigate to the Visual Effects tab, select the “Adjust for best performance” option, or manually disable specific visual effects that consume memory.

10. Update Windows and device drivers: Keeping your Windows 10 up to date with the latest updates and device drivers can optimize memory usage, as they often include performance improvements.

11. Add more RAM: If you frequently experience high memory usage, consider upgrading your RAM to provide your system with more memory capacity.

12. Use third-party optimization tools: Various reliable third-party tools, such as CCleaner, Wise Memory Optimizer, or IObit Advanced SystemCare, can help optimize your computer memory by clearing temporary files, unnecessary data, and identifying memory leaks.
