5 Best Free System Optimizers for Windows 10 in 2019

Computer Cleaning and Optimization

During installation, programs create some temporary data on the computer drive, which is not deleted by default. As we keep on using these programs, more temporary files are created. Sometimes this temporary data is helpful for the user, like browser cache, but most of the times it’s just junk. You’d think that uninstalling these programs would also delete all of the files that they created, right? Well, that’s what the logic says, but in reality it doesn’t work this way. When we uninstall a program, its associated files and folders, settings, and shortcuts are not always deleted.
