(or DMI Tool) allows users to view or modify critical system information stored in the BIOS/UEFI, such as serial numbers, product IDs, and UUIDs. These tools are most commonly used by technicians after replacing a motherboard to "brand" the new board with the original system's identity. Primary DMI Editor Tools by Manufacturer

A DMI Editor allows users to view and edit the data. This data contains unique system identifiers such as: System Serial Numbers Model Names Asset Tags UUIDs (Universally Unique Identifiers)

If you own a pre-built PC (like a Dell or HP) and the motherboard fails, you might replace it with a generic motherboard or a different manufacturer's board.

A DMI editor allows you to flash the correct Service Tag back into the new board.

When you look at "System Information" in Windows or enter the BIOS/UEFI setup screen, you are seeing DMI data. This includes:

HP technicians often use tools like the or HP BIOS Configuration Utility to restore serial numbers after a motherboard replacement.
