Smooth system performance depends heavily on how efficiently your computer manages memory. If your Windows PC starts to feel sluggish, especially after being on for hours, then high memory usage could be the culprit. While Windows manages memory decently on its own, a little help can go a long way in maintaining peak performance. Wise Memory Optimizer is a simple yet powerful tool that helps you monitor memory consumption and automatically optimize it for better performance.

Understand "Free Memory" in Windows

Before we start optimizing, it is crucial to understand that in modern Windows, "free" memory is not always the goal. Windows uses unused RAM as a cache to make your system faster. It pre-loads frequently used data so apps can launch and files can open more quickly.

The real problem is when there is no RAM left for new applications. This forces Windows to use the page file (a file on your hard drive acting as slow RAM), which causes significant slowdowns.

A memory optimizer's job is to intelligently flush unnecessary cached data only when your available RAM is critically low, preventing this slowdown without constantly interfering with Windows's efficient caching system.

Check Memory Usage Easily with Wise Memory Optimizer

Step 1. Download and Install

Download the latest version of Wise Memory Optimizer from the official website. Run the installer and follow the on-screen instructions.

Step 2. View Memory Usage

  • After installation, launch the software. You will then notice there is a system tray of Wise Memory Optimizer on Taskbar.
  • Move your cursor to this system tray and keep hovering over it.
  • Then you can view the current memory usage that pops up without opening the software.

Auto Free Up Memory using Wise Memory Optimizer

Wise Memory Optimizer includes an auto optimization feature, ensuring your PC runs efficiently without manual intervention. Below is how to enable it:

Step 1. Right-click on the tray

Right-click on system tray on Taskbar.

Step 2. Set up Auto Optimize

On the drop-up menu that pops up, click Auto Optimize and select an option you prefer (recommend “If free memory is low”).

Conclusion

Checking and optimizing memory usage is essential to maintain a fast and stable Windows PC. While Task Manager can show memory usage, Wise Memory Optimizer goes a step further by freeing up RAM instantly and automatically.
