A slow Windows PC? Check these basics first.

A slow computer does not automatically need new hardware. Save your work first, then make one change at a time so you can tell what helped.

1. Restart and simplify

Restart the PC and reopen only what you need. Close unused browser tabs and applications. If the slowdown happens in one application, check whether other applications work normally.

2. Look at Task Manager

Press Ctrl + Shift + Esc to open Task Manager. Look at CPU, Memory, and Disk usage. A brief spike is normal; sustained high usage helps identify what deserves attention. Do not end unfamiliar Windows or security processes.

3. Check storage space

Open Settings and search for Storage. Review large files and storage recommendations. Move files you need to a backed-up location before deleting anything, and review the Recycle Bin before emptying it. Avoid deleting system folders manually.

4. Review startup applications

In Task Manager, review Startup apps. Disable only optional applications you recognize and do not need at sign-in. Keep security, backup, accessibility, and work-management tools enabled unless your administrator advises otherwise.

5. Check for a pattern

Note whether the slowdown began after an update, installation, or hardware change. Use your operating system’s built-in update and security tools. If the PC repeatedly freezes, overheats, or makes unusual mechanical noises, back up important files and get qualified help before attempting repairs.
