How to clean up your PC for maximum performance

Organise your desktop and remove junk files

It’s time to make resolutions to detox and declutter. We show you how to apply the same resolve to your PC life, speeding up your machine in the process.

Clean out junk files to restore PC performance

Step 1. As your PC ages, a range of data will fill up the hard drive and slow performance. Remove the junk to restore the zip it once had. Begin by deleting duplicate files (commonly found in music and image libraries). The free Easy Duplicate File Finder can speed up this process.

Step 2. Use Windows 7’s Disk Cleanup Wizard to empty the Recycle Bin, and remove temporary and other files you no longer need. Go to Start, All Programs, Accessories, then choose System Tools, Disk Cleanup. Alternatively, use the Start menu Search bar to quickly locate the Disk Cleanup Wizard.

Step 3. The wizard will identify the files it thinks you can delete, also telling you how much hard-drive space it will free up. Click ‘View files’ if you aren’t sure which files it’s pointing to. If it offers to delete a file you want to keep, simply remove the tick in the box beside it before clicking ‘Clean up system files’.

Step 4. Next, remove any programs you don’t use – Windows has its own tool for this. Head to Start, Control Panel, Programs and choose ‘Uninstall a program’. Scroll down the list and select the program you want to remove, then click the Uninstall button at the top of the window.
