How to Speed Up a Slow Windows 7 PC
Practical steps to bring a sluggish Windows 7 machine back to life without a full reinstall.
A Windows 7 PC that's slowed to a crawl is usually suffering from one of a handful of common causes: too many programs launching at startup, a fragmented hard drive, or simply running low on free disk space. Before assuming you need new hardware, it's worth working through a few basic checks.
Start by reviewing your startup programs through the System Configuration tool (msconfig) and disabling anything you don't recognize or don't need running in the background. Antivirus and cloud sync tools are legitimate, but toolbars and "helper" apps that came bundled with other software rarely are.
If your PC uses a traditional spinning hard drive (not a solid-state drive), running Disk Defragmenter periodically helps keep file access fast. Also check Disk Cleanup to clear out temporary files, and make sure you have at least 15-20% free space on your main drive — a nearly full drive slows down almost everything.
