A Windows cache cleaner is a software tool designed to remove temporary files, system files, and other data that accumulates on your computer over time. This accumulated data, also known as cache, can take up significant space on your hard drive and slow down your PC. A cache cleaner helps to clear out this junk data, freeing up space and improving your computer's performance.
When RAM is not fully utilized, Windows moves data to the "Standby List." While not a "disk cleaner" function, advanced system cleaners often include RAM optimization features that flush this list, forcing the OS to reload data from the slower disk drive. windows cache cleaner
