Sometimes when you plug in a new device (like a printer or USB drive), your computer doesn’t notice it right away. This guide will show you simple ways to tell Windows to look for new hardware so it can work properly.

Why Scan for Hardware Changes?

• If Windows doesn’t automatically detect your new device, scanning helps your computer find it.
• It allows Windows to install the right drivers (software that helps your device work).
• It can also find some older devices that don’t tell Windows when they’re connected.

Important: You need to be signed into your computer as an administrator to do this.

Method 2: Use a Command in Windows Terminal

If you like using commands, you can do this:

• If prompted by User Account Control, click Yes.

Step 2: In the terminal window, type or copy-paste this command and press Enter:

pnputil /scan-devices

This command tells Windows to scan for new devices and install drivers if needed.

Step 3: When it finishes, you can close Windows Terminal.
