Capable of running in both 32-bit and 64-bit processing environments depending on the executable variant chosen (e.g., AMIDDE or DMIEDIT ).
DMIEdit is a powerful utility used to modify Desktop Management Interface (DMI) data, often for tasks like updating serial numbers or UUIDs in a computer's BIOS.
DMI data is organized into "structures" (also called "types"). For example:
The benefits of using DMIE 5.20 are numerous. Some of the most significant advantages include:
: Game developers (like Riot Games with Vanguard) have evolved to detect when DMI tables have been tampered with or when "generic" serial numbers are used, leading to a constant cat-and-mouse game between the software developers and those using DMIEdit. Legal and Safety Warning dmiedit 5.20
Large IT departments assign asset tags to every machine. These tags are physically printed on a sticker, but they are also stored in the DMI. If a sticker falls off, DMIEdit 5.20 allows you to re-write the asset tag field for remote inventory software (like SCCM or LANDesk) to correctly identify the machine.
To change a value, you will target a specific flag. The most common commands include: amidwin.exe /SS "NewSerialNumber123" Use code with caution. To change the System UUID (Universally Unique Identifier): amidwin.exe /SU AUTO Use code with caution.

: Use specific flags to update information. For example: /SS "NewSerialNumber" – Updates the system serial number. /SP "ProductName" – Updates the product name. /ALL – Displays all current SMBIOS data for verification. UEFI Shell (AMIDEEFI)
dmiedit 5.20 -t 1 -i 1 -f uuid "12345678-1234-1234-1234-123456789abc"
Use the following core syntax structure to read and write data: Common Command-Line Arguments: AMIDEWINx64.exe /ALL Use code with caution. Modify System Serial Number: AMIDEWINx64.exe /SS "NewSerialNumber123" Use code with caution. Modify Baseboard (Motherboard) Serial Number: AMIDEWINx64.exe /BS "NewBaseboardSerial" Use code with caution. Modify System Product Name: AMIDEWINx64.exe /SP "ProductModelName" Use code with caution. Modify System UUID: AMIDEWINx64.exe /SU AUTO Use code with caution.
Version 5.20 brings several enhancements over its predecessors: For example: The benefits of using DMIE 5
When a technician replaces a damaged motherboard in a branded PC (like Dell, HP, or Lenovo), the new motherboard often arrives with blank serial number fields. Using DMIEDIT 5.20, the technician can burn the original chassis serial number back into the BIOS, keeping the manufacturer warranty valid and maintaining consistent IT asset logs. 2. Corporate IT Asset Management
Despite being several years old, remains a gold-standard utility. Modern motherboard manufacturers have increased firmware security (PCR0, Secure Boot, Intel Boot Guard), making DMI writes harder. However, for consumer-grade boards (ASUS, Gigabyte, MSI, ASRock) and older enterprise hardware (pre-2020), DMIEdit 5.20 works flawlessly.
: Allows modification of specific SMBIOS "Types," such as Type 1 (System Information) and Type 2 (Baseboard Information). Environment Support : Versions exist for AMIDEWINx64.exe AMIDEEFIx64.efi GUI and CLI
