Overview

Auslogics BoostSpeed is a PC maintenance and optimization utility for Windows. It checks the system for junk files, registry errors, fragmented drives, unneeded startup programs and other causes of slowdowns. The user can then fix these problems from one program. BoostSpeed comes in a free edition that covers diagnostics and essential optimization. A paid Pro edition, sold as a yearly subscription, unlocks the advanced tools and automation.

System checkup

The starting point in BoostSpeed is a full system scan. It looks across the PC for junk files, issues that reduce speed and possible causes of crashes or glitches. It groups its findings so the user can see where problems are before making changes. The repair methods are designed to work without damaging the operating system.

Junk and duplicate cleanup

The junk cleaner goes through the usual places where Windows and applications leave temporary data: temp folders, caches, old log files and similar leftovers. After the scan, the cleaner removes the found items in one step to free disk space. The free edition handles basic junk cleanup, while Pro adds more cleanup options for recovering extra space.

A separate duplicate finder looks for repeated copies of images, documents and other files. It presents the results as lists the user can review, so the copies worth keeping stay on the drive. It then deletes the selected duplicates together.

BoostSpeed can also slim down Windows itself. This tool reduces the disk space that system files and data occupy. It also adjusts Windows privacy settings in the same place.

Registry repair

The registry cleaner searches the Windows registry for invalid, empty or corrupt keys and removes them. These keys can cause errors and odd program behavior. The free edition performs a basic registry cleanup; the Pro edition runs the full cleanup.

Drive optimization for HDD and SSD

BoostSpeed treats the two drive types differently. On traditional hard drives, defragmentation puts the scattered pieces of files back together so data can be read faster. On SSDs it uses special algorithms to arrange data placement in a way meant to help extend the drive’s life.

Standard defragmentation is part of the free edition. Pro adds Intelligent Defrag, which also optimizes where files sit on the drive for a further speed gain. It also adds full SSD optimization and scheduled defragmentation, so drives receive maintenance without the user starting the job by hand.

Startup and installed programs

The startup tool lists the applications that launch together with Windows. The user can disable the ones that are not needed at boot, which shortens the time Windows takes to start.

For programs that are no longer wanted, BoostSpeed includes an uninstaller. Besides removing the application, it tries to clear the traces that a normal uninstall often leaves behind.

Privacy and browsing

The privacy tools in Auslogics BoostSpeed remove traces of the user’s activity. They also help protect sensitive information stored on the drive, such as saved passwords and card details. The free edition offers basic privacy protection. Pro extends it to all data stored on the PC and adds a Browser Anti-Tracker aimed at online tracking.

Internet optimization is also split by edition. In the free version, the user applies connection settings manually, while Pro can apply the optimization automatically.

Scheduled maintenance

Instead of running each tool by hand, BoostSpeed Pro can follow a schedule. The scheduler runs regular scans and maintenance automatically, detecting and fixing issues. This cleans and tunes the PC without the user stepping in each time.
