Simple Ways to Speed Up a Slow Windows Computer

A computer that used to feel snappy and now feels sluggish usually isn't failing — it's accumulated clutter, background processes, and neglected maintenance. Work through these steps in order; most people see a noticeable improvement before reaching the end of the list.

1. Restart properly, not just put it to sleep

Sleep mode keeps old processes and memory usage lingering in the background. A full restart clears all of that out. If it's been more than a few days since your last full restart, start there before anything else.

2. Check what's launching at startup

Open Task Manager (Ctrl + Shift + Esc), go to the Startup tab, and look at what's set to launch automatically. Disable anything you don't need running the moment you log in — this alone often fixes a slow startup.

3. Free up disk space

A drive that's nearly full runs noticeably slower than one with breathing room, especially for the drive holding Windows itself. Go to Settings > System > Storage and use Storage Sense to clear temporary files, old downloads, and unused installers.

4. Uninstall programs you no longer use

Old software can run background services even when you never open it. Go to Settings > Apps > Installed apps and remove anything you haven't used in the last six months or don't recognize.

5. Check for malware and unwanted programs

Malware and bundled "bloatware" are common, often overlooked causes of slowdowns. Run a full scan with Windows Security (built in and free) under Settings > Privacy & Security > Windows Security > Virus & threat protection.

6. Manage background apps

Some apps keep running and consuming memory even after you close their window. Check Task Manager's Processes tab, sorted by Memory or CPU usage, to identify anything unexpectedly resource-heavy.

7. Keep Windows and drivers updated

Updates often include performance improvements alongside security fixes. Go to Settings > Windows Update and install anything pending, including optional driver updates, which can resolve specific slowdowns tied to graphics or storage hardware.

8. Reduce visual effects

Animations and visual effects look nice but cost a small amount of performance, especially on older hardware. Search "Adjust the appearance and performance of Windows" in the Start menu and select "Adjust for best performance" to strip these back.

9. Check your browser, not just your computer

Dozens of open browser tabs and heavy extensions are one of the most common — and most overlooked — causes of a computer feeling slow. Close tabs you're not actively using and disable extensions you don't need running at all times.

10. Consider a hardware upgrade — but only after the above

If your computer is several years old and still feels slow after all the steps above, adding more RAM or switching to a solid-state drive (SSD) are the two upgrades that make the most noticeable difference, often more than buying an entirely new computer.
