Many of us think that when a computer starts performing poorly then it's time to buy a new computer. Does your desktop or laptop often hang on the hourglass for several minutes at a time? Is it slow to load files or applications, and does it take a long time to boot? Even if you're extremely careful about how you use your computer and never download questionable material, over time it is inevitable that your system will accumulate unwanted registry entries, errors, clutter and debris. It's important to clean your computer up and get it running faster again.
