ByIf new hardware installed on your Windows PC is not appearing, a device stops working after a driver update, or the system fails to recognize a USB device, printer, GPU, SSD, keyboard, mouse, or other peripheral, the Scan for Hardware Changes feature serves as the most useful solution. Through this process, the Windows system re-detects the hardware and loads the necessary driver configurations.
In this comprehensive guide, we will outline 5 effective methods to scan for hardware changes in Windows, enabling you to resolve device recognition issues without having to restart your system.
What is “Scan for Hardware Changes”?
When we add new hardware to a computer or remove existing hardware, Windows requires information regarding that change. Often, the system does not recognize the change immediately. In such instances, the Scan for Hardware Changes command instructs Windows to re-examine all connected devices.
This feature is useful in the following situations:
A new USB device is not being recognized.
A connected printer is not appearing.
An SSD or HDD is not visible.
Issues arise after installing a GPU or Sound Card.
A device disappears following a driver update.
An “Unknown Device” appears in the Device Manager.
1. Scan for Hardware Changes via Device Manager
This is the easiest and most popular method.
Steps:
1. Right-click on the Start Menu.
2. Open Device Manager.
3. Navigate to the Menu Bar at the top.
4. Click on Action.
5. Select Scan for hardware changes.
Windows will immediately scan the system and search for new devices.
When to Use:
A USB device is not being detected.
The Bluetooth adapter is missing.
There are issues with the mouse or keyboard.
The printer is not appearing.
Benefits:
Simple method.
No additional commands required.
Useful for all users.
2. Scan for Hardware via Command Prompt
If Device Manager is not working or you need a faster method, use the Command Prompt.
Steps:
1. Open the Start Menu.
2. Search for CMD.
3. Select Run as Administrator.
4. Run the following command:
“`cmd
pnputil /scan-devices
“`
Windows will then scan for all hardware devices.
When to Use:
For Advanced Troubleshooting
For Remote Support
For IT Administration tasks
Benefits:
Faster process

3. Scan for Hardware Changes via PowerShell
PowerShell is Windows’ modern administrative tool.
Steps:
1. Open the Start Menu.
2. Open Windows PowerShell (Admin).
3. Run this command:
“`powershell
pnputil /scan-devices
“`
Or
“`powershell
Get-PnpDevice
“`
Benefits:
Scripting support
Bulk system management
Better suited for Admin Users
4. Remove Hidden Devices and Rescan
Often, old drivers or “Hidden Devices” can block new hardware. In such cases, first remove the hidden devices, and then perform a scan.
Steps:
1. Open Device Manager.
2. Click on View.
3. Select Show hidden devices.
4. Remove any grayed-out devices.
5. Now, click Action > Scan for hardware changes.
When to Use:
If an old printer keeps reappearing
If there is a USB driver conflict
If there is a Bluetooth error
Benefits:
Resolves old conflicts
Detects new hardware more quickly
5. Refresh Hardware Without Restarting
If the scan method isn’t working, refresh the system by disabling and then re-enabling specific devices.
Steps:
1. Open Device Manager
2. Right-click on the problematic device
3. Select Disable device
4. Then, enable the device again
5. Now, select Scan for hardware changes
Useful Scenarios:
Wi-Fi Adapter not working
Sound Device Error
Camera not being detected
What to do if the hardware still doesn’t appear after scanning?
If the device is still not visible after scanning, try the solutions listed below:
1. Change the USB Port
Sometimes, the port itself is faulty.
2. Update Drivers
Device Manager > Update Driver
3. Check in BIOS
The Storage Drive, GPU, or USB Controller may be disabled within the BIOS.
4. Update Windows
Pending updates can sometimes interfere with hardware detection.
5. Check Cables
Loose SATA, power, or USB cables can cause issues.
