If you are reading this article, then you are wondering why your computer is gradually becoming slower and slower and you’re looking for a RAM cleaner for Windows to fix that.

Computers tend to build up data on your HDD and RAM which can cause your PC to run slower.

If you are in this situation, then you may want to try one of the RAM optimizers for Windows 10 and 11 in the list below.

It is important to note that these RAM manager apps will not magically add more memory to your RAM or make it more powerful.

Rather, optimizing your RAM can be seen as a sort of clean-up, maintenance job to free and optimize its usage.

These programs will help improve your computer by deleting unnecessary tasks from the memory, among other things.

The truth is, these programs are not essential, because Windows 10 and 11 already have integrated functions and tools that are designed for this sort of thing.

How do I manually clean my RAM on Windows 10 & 11?

1. Clean your RAM using Command Prompt

  1. Click the Start button, type cmd, and select Run as administrator from the results (If it does not work at first, don’t worry, we have the right tips for when you can’t run CMD as admin).
  2. Now, enter the following command: ipconfig /FlushDNS
  3. Finally, close the window and your PC should have a clean memory available!

2. Clean your RAM using Task Manager

  1. Right-click the Start button and select Task Manager from the list.
  2. Go to the Startup tab.
  3. Once you’re there, locate the programs you don’t really need to be loaded at startup.
  4. Select them once by one and press Disable.

Now, these are not at all complicated maneuvers. But they do take time and isn’t that the most precious resource we all lack these days?

Even though they are not extremely demanding, the integrated tools can be confusing to individuals who aren’t computer savvy.

On the other hand, specialized RAM cleaner tools and RAM optimizers tend to be easy to use and convenient, and most of them are completely free.
