Before changing anything, document your current serial numbers so you can revert them if something goes wrong. Run these commands: amidewin.exe /SU amidewin.exe /BS Use code with caution. Step 5: Modify the Identifiers
What is your in using Amidewin (e.g., restoring a serial number, fixing an error, or something else)? Share public link
Amidewin is an official utility developed by . Its primary purpose is to allow administrators to edit strings within the BIOS without having to flash a entirely new firmware file. This includes: System Serial Numbers UUIDs (Universally Unique Identifiers) Baseboard Asset Tags Chassis Serial Numbers
Because Amidewin.exe modifies sensitive BIOS/NVRAM data, Windows Security often flags it as a "Trojan" or potentially unwanted program (PUP) and deletes the file immediately after download.

Visit the American Megatrends (AMI) website or the website of your motherboard manufacturer (e.g., ASUS, MSI, Gigabyte) to download the latest firmware update tools.
To run Amidewin.exe , you must execute it through an administrative Command Prompt or PowerShell window. Running the executable by double-clicking it will simply open and instantly close a black window. Step-by-Step Execution
If your antivirus suddenly flagged the file, it is likely safe.
For model-specific serial writing instructions, see community guides on the Lenovo Forums Are you attempting to fix a specific hardware mismatch error or are you trying to recover a lost serial number after a repair?
At its core, the primary function of Amidewin.exe is to allow users and technicians to modify BIOS strings, such as serial numbers, UUIDs, and system model information, without having to enter the BIOS interface directly. This is often necessary for system administrators who need to relabel hardware in a corporate fleet or for technicians repairing a motherboard where the original serial number must be restored to maintain warranty or licensing status. In these professional contexts, the tool is a vital part of the hardware lifecycle, ensuring that software licenses tied to specific hardware IDs remain valid after component replacements.
