You are probably wondering what memory cleaner options to try, here is all you should know.

When you buy a new computer, it comes loaded with stuff that you don’t need that can take up memory and make it slower, and this isn’t how a brand-new machine should ordinarily behave.

Everybody wants a PC that delivers fast startup and runs operations at peak capacity, regardless of the brand or price of the machine.

However, you cannot escape the slow computer issue because it will happen over time or even soon as you upload your files from a hard drive or other storage devices.

What is the best way to clear memory?

You can either choose to do it manually, by closing background processes, or you can use one of the best-specialized memory cleaners:

  • Fortect – Universal repair tool
  • IObit Advanced System Care – Excellent speed-up feature
  • System Mechanic Ultimate Defense – Great for bloatware removal
  • Ashampoo WinOptimizer – Powerful one-click PC optimizer
  • Advanced System Optimizer – Secure deletion and optimization
  • CCleaner – Great for add and driver update
  • Tweaking Windows Repair – Lightweight option

What is a memory cleaner?

Memory cleaners are apps that check your computer and fix the troublesome spots by defragmenting your hard drive, repairing the registry, and freeing up memory by getting rid of unnecessary and duplicate items on your computer – but some go the extra mile.

Cached RAM (also known as SRAM) is closely linked to your CPU and stores data frequently executed by it. The purpose is to provide accelerated and smooth access to commonly used programs by memory caching the recurrent instructions.

But sometimes, RAM cache can end up working against you rather than for you as these temporary files pile up and eventually slow down your PC or send CPU values through the roof when browsing the Internet.

Does Windows have a memory cleaner?

Yes, ti does. You could use Microsoft’s Windows Refresh tool that purges all apps and leaves your computer in a pristine state.

But there are other stronger tools that exist solely to help your computer get its groove back and work as if it has just undergone a factory reset.

Another tool is CRUDD (Commonly Redundant or Unnecessary Decelerators and Destabilizers). This removes unnecessary files that jam your computer and eliminate any extra programs that are installed together with programs you add to your computer.

Other tools include LiveBoost to boost your CPU and RAM, plus ActiveCare, which performs analysis and repair on your system. You can also get an anti-malware tool if you upgrade to the Iolo System Mechanic Pro.

When you finish running any program on your system, the Memory Optimizer ensures that memory is correctly allocated. There is even a Game Optimizer, which provides a unique environment in which games may run efficiently.

Secure Remove is a function that allows you to delete files and folders safely and permanently. It really implements a mechanism developed by the United States Department of Defense. Secure Delete deletes any private or sensitive information permanently, and no program can restore any files or folders erased with Secure Delete.

There are certain drawbacks to the software, such as the lack of a progress meter and the invasive reboot request for your PC. To minimize conflicts or unexpected PC reboots, we recommend using each feature independently. This way, you may utilize it without the risk of crashes or freezing.
