Is there any way to change device name in Registry?

Changing the device name in the Registry will update it globally across your system. Be cautious when modifying the Registry, as incorrect changes can cause system instability or corruption. If you're unsure about making changes to the Registry, consider using a registry editor with built-in backup and restore features, such as Cleaner or Regedit.

Still within the same path, you can also change the RegisteredOwner value if you want to change the owner's name as it appears in various system details. Double-click on RegisteredOwner and enter the new name.

1.Open the Registry Editor:
Press Win + R to open the Run dialog.
Type regedit and press Enter. If prompted by User Account Control (UAC), click Yes to open the Registry Editor.
Navigate to the following path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
2.Find and Modify the Hostname:
Look for a value named Hostname in that location. If you don't see it, you might need to create it. To do this:
Right-click in the right pane and select New > String Value.
Name it Hostname.
Double-click on the Hostname value and enter the new device name you want to use.
3.Change the Computer Name:

Additionally, you may want to change the NV Hostname value in the same location (not always present).
Update Network Configuration:
You may also want to update the value in this Registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
Locate your network interface (there may be several) and change the HostName value.
4.Reboot Your Computer:
After making these changes, restart your computer for the changes to take effect.

Before making any changes, it's wise to back up the Registry. You can do this by clicking on File > Export and saving the current state. This way, if something goes wrong, you can restore it.

Before making any changes, it's wise to create a backup of your Registry settings. You can do this by right-clicking on the Registry folder or specific keys and selecting Export. This way, you can restore them if anything goes wrong.

When you’re entering the new device name, make sure it doesn't include special characters or is too long. Stick to alphanumeric characters for best results.

If your goal is simply to change the device name for easier identification (like for a PC), you can do this without touching the Registry:

1. Open Settings: Go to Start > Settings (the gear icon).
2. System: Click on System > About.
3. Rename this PC: Click the Rename this PC button. Enter your desired name and follow the prompts.
