FAQ: Learn more about PC repair and optimizer software

  • Why do I need a PC optimizer?

  • Are PC repair programs efficient?

Many PC repair tools offer solutions that not even Windows 10 has covered with its built-in tools, such as advanced file recovery, or system defragmenters. The latter are especially useful when Windows 10’s built-in defragmenter stops working.

  • Should I go for free PC repair and optimizer software?
