How to speed up computer performance

After prolonged use of a computer, the operating system may slow down. This slowdown is caused by a large number of excess files and Windows registry errors that accumulate during operation.

The operating system may also be slowed down by installed applications that are rarely used. Many of these applications may run as soon as the operating system loads and can significantly slow down the computer. You may even have no idea that a specific application is running in the background using up computer resources.

To speed up computer performance:

  1. Open the main application window.
  2. Click the Speed up PC button.
  3. In the opened Speed up PC window:
    • In the Speed up computer performance block, click the Start button (or View if the search was already performed).

      The application performs a search and generates a report with the following contents:

      • Unused system files. Click the block to view a detailed report on the operating system files that are not being used. Click the Clear button to delete these files.
      • Windows registry errors. Click the block to view a detailed report on the Windows registry errors that you can delete without risking damage to the operating system. Click the Fix button to fix detected errors.
    • Click on the Speed up startup section to view a report that shows which autorun applications are slowing down the computer. Switch the Autorun toggle next to the application to Off and click Done.
    • Click Free up space to free up hard drive space. In the opened window, search for unnecessary files.
      • Duplicate files. Click the Find button to start searching for duplicates of files. You can specify the search range in the drop-down list. In the search results window, select the files and click Delete.
      • Large files. Click the Find button to start searching for large files. You can specify the search range in the drop-down list. In the search results window, select the files and click Delete.

        Large file search does not work for files that have two or more hard link references in the operating system.

      • Unused applications. Click the Find button. The search results report contains a list of applications that have not been used in more than three months. Select an application and click Remove.
