5 of the Best Tools to Delete Temporary Files on Windows

Windows creates and stores temporary and other cache files on your computer to allow programs to run faster. These files eventually accumulate and take up your computer’s valuable space, while also slowing it down and causing performance issues. Therefore, it is crucial to regularly remove unnecessary temporary files to optimize your computer’s performance. Take a look at this shortlist of the top tools designed specifically for this purpose.

It is a convenient tool that can quickly clean your computer’s waste and boost its speed. To access the utility, click the Search button in Windows and type “Disk Cleanup.”
