Wise Memory Optimizer is a Windows utility from WiseCleaner, the company behind Wise Disk Cleaner and Wise Registry Cleaner. It shows how your RAM is being used and lets you free some of it quickly. It is free and runs on everything from Windows XP to Windows 11, 32-bit and 64-bit.

What Wise Memory Optimizer is for

When you open it, the program shows used, available and total memory with a pie chart. The Optimize button releases memory held by idle applications and empties the standby list, which is the cache Windows keeps so recently used programs reopen faster. An automatic mode kicks in when available memory drops below a level you set, and can be limited to times when the CPU is idle. There is also a portable version you can run from a USB stick.

Who is it for?

Wise Memory Optimizer can help on an older PC with little RAM that bogs down after hours of use. On a recent computer the effect is usually small: Windows handles memory on its own, and clearing the cache can make some apps a little slower to reopen. Think of it as a troubleshooting tool rather than a speed fix.

Download Wise Memory Optimizer safely

Download it from wisecleaner.com, the publisher’s official site, as an installer or a portable version. Copies on hosts such as Mediafire or in software bundles are out of date and may have been tampered with.

Our opinion
