How to scan for hardware changes on Windows

Sometimes, you may need to scan for hardware changes manually when Windows does not immediately recognize (detect) connected devices. In this case, the peripheral device will not display in Device Manager. Running a scan to detect hardware changes can also resolve issues related to drivers and hardware conflicts.

Here's how you can scan for hardware changes on your Windows PC.

2. Click Device Manager to open that utility's window.

3. Select the device category in the window.

4. Next, click the Action menu .

5. Select the Scan for hardware devices changes option .

Alternatively, right-click the device and select Scan for hardware changes on that device's context menu. You should do that for devices that display exclamation marks. The exclamation mark emphasizes that there is a problem with the device, which selecting Scan for hardware changes can fix.

You can also select the Scan for hardware devices option to reinstall the device driver. To uninstall a device, right-click on it to select the Uninstall Device option ; Select the Attempt to remove driver for this device or Delete driver check box on the prompt that appears and click Uninstall . Then select Scan for hardware devices as stated above.
