  • Iolo System Mechanic
  • CCleaner
  • Ashampoo Win Optimizer
  • Iobit Advanced SystemCare

Stop! Right there and question yourself is there an actual issue with your device?

Most of the junk on your devices such as temporary files, browser history, cache, or cookies that make your system slow can be easily removed using the in-built Windows tools. If you are looking for the best registry cleaner, you can use the free CCleaner that does its job very perfectly. Other than that, your system only needs smart cleaning and not expensive cleaners.
