HWID - Unique hardware identifier

Unique identifier - serves for binding the agent to the system and the data that it sends to the server. An agent receives HWID in this order:

  • Serial number of the hard disk.

  • If comes an error, then MAC

  • If comes an error, then the serial number of the volume.


Starting from the agent version 5.8.2478 hwid is generated automatically in the registry.

Starting from the agent version 5.8.2450 there is a possibility to set HWID in the Windows registry, for this you need to create a value of the “REG_SZ” type.


It also makes sense to correct the HWID if the Wrong CN! error occurs in the agent’s log.

Edit the value of the hwid registry, excluding whitespace.

Or create a file with content (set your own HWID value according to the template XXXX-YYYY)

Windows Registry Editor Version 5.00


Automatic HWID generation

The text below should be copied and pasted into a file, for example hwid.bat.

@echo off
reg query "HKLM\SYSTEM\SCHWID" /v "hwid" >nul
if  %errorlevel% equ 0 goto end
set I=26
set N=16
set CHAR=0 1 2 3 4 5 6 7 8 9 A B C D E F
set Hex=0
set /a R=1+%N%*%random%/32768
for /f "tokens=%R%" %%q in ("%CHAR%") do (set Hex=%%q%Hex%)
Set /a I-=1
If %I% GTR 0 goto LOOP
echo %Hex%

reg add HKLM\SYSTEM\SCHWID /v hwid /t REG_SZ /d %Hex%

You can run this script with the command:

cmd.exe /c hwid.cmd

After that, the unique identifier will be written into the system registry and will never be able to change.
