What Makes a PC Run Quicker?

Several things make a computer run faster. The good news is you can do most of them yourself without spending money.

Keep Windows Updated

Windows updates aren’t just about security. They also fix slowness problems. Go to Settings, then “Update & Security,” and check for updates at least once a month.

Restart Weekly

Make it a habit to restart your computer at least once a week. This simple step prevents memory problems from building up. Many people who complain about slow computers haven’t restarted in weeks.

Use One Browser at a Time

Every browser window uses memory. If you have Chrome, Edge, and Firefox all open at once, your computer struggles. Pick one browser and close the others.

Scan for Viruses

Viruses and malware make computers run slowly on purpose. Windows Defender scans automatically, but you can run a manual scan too. Open Windows Security from your Start menu and click “Virus & threat protection,” then “Quick scan.”

According to AARP’s tech guidance for seniors, keeping your antivirus software active and updated protects both your speed and your personal information.
