Create a lean, mean speed machine

Keeping a PC in shape is as important as tuning your car’s engine. To rev up performance, regularly clear system clutter and delete all junk. Here are some top tips:

Perform a disk cleanup

Did you know that installations are messy? They leave behind temporary files that hog your system. Clear these and other junk files.

Clear out your hard drive

This leaves more space for the important files, like your holiday photos.

Perform a registry repair

Get rid of the errors that cause freezes and slow down your startups.

Empty your recycle bin

You don’t need this trash! Plus, trash files may contain viruses that can infect your computer if you don’t  remove them quickly.
