In previous article, we mentioned Best 8 PC cleaner software for Windows but in this article, I have mentioned some of the best RAM cleaner or applications to free up your RAM so you can boost your Windows PC performance.

A RAM cleaner is a software that frees up your RAM to speed up your computer. As you use your computer, more processes take up space in your RAM, and your computer becomes slower.
