How to Speed Up a Slow Windows Computer

Published on June 23, 2026

A slow computer is incredibly frustrating. Over time, Windows operating systems build up temporary caches, duplicate files, startup items, and background logs that hog CPU and RAM resources. Here are standard steps to optimize speed:

1. Disable Startup Programs

Many programs configure themselves to start when Windows boots, running constantly in the background. Press Ctrl + Shift + Esc to launch Task Manager, head to the Startup tab, and disable applications you do not need immediately.

2. Run Disk Cleanup

Windows has a built-in clean utility. Search "Disk Cleanup" in the Start Menu, choose your system drive, and clear temporary files, update backups, and Recycle Bin items.

3. Check for Malware

Viruses often run background processes that consume major processor capacities. Run a deep security scan to ensure your machine is free of adware, spyware, and trojans.
