Sets environment variables in the local or system environment, without requiring programming or scripting. Setx also retrieves the values of registry keys and writes them to text files.
 
 
Syntax
setx [/s Computer [/u [Domain\]User [/p [Password]]]] VariableValue [/m]

setx [/s Computer [/u [Domain\]User [/p [Password]]]] [Variable] /k Path [/m]

setx [/s Computer [/u [Domain\]User [/p [Password]]]] /f FileName {[Variable] {/a X,y | /r X,y "String"} [/m] | /x} [/d Delimiters]

Parameters
/sComputer
Specifies the name or IP address of a remote computer (do not use backslashes). The default is the local computer. This parameter applies to all files and folders specified in the command.
/u [Domain\]User
Runs the script with the permissions of the specified user account. The default is system permissions.
/p [Password]
Specifies the password of the user account that is specified in the /u parameter.
Variable
Specifies the name of the environment variable that you want to set.
Value
Specifies the value to which you want to set the environment variable.
/kPath
Specifies that the variable is set based on information from a registry key. Specify Path the \HIVE\KEY\...\Value format (for example, HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ TimeZoneInformation\StandardName).
/fFileName
Specifies the file that you want to use.
/aX,y
Specifies absolute coordinates and offset as search parameters.
/rX,y"String"
Specifies relative coordinates and offset from String as search parameters.
/m
Specifies to set the Variable in the system environment. The default is the local environment.
/x
Displays file coordinates. Ignores the /a, /r, and /d command-line options.
/dDelimiters
Specifies additional delimiters such as "," or "\". The four built-in delimiters are SPACE, TAB, ENTER, and LINEFEED. You can use any ASCII character as an additional delimiter. The maximum number of delimiters, including the four built-in delimiters, is 15.
/?
Displays help at the command prompt.
Remarks
  • Using the /s, /u, and /p command-line options The /u and /p command-line options are available only when you use /s. You must use /p with /u to provide the user's password.
  • Setx provides the only command-line or programmatic way to directly and permanently set system environment values. System environment variables are manually configurable through Control Panel or through a registry editor (Regedit.exe). The Set command, which is internal to the command interpreter (that is, Cmd.exe), sets user environment variables for the current console window only.
  • You can use setx to set values for user and system environment variables from one of three sources: Command Line Mode, Registry Mode, or File Mode.
  • Setx is similar to the UNIX utility SETENV.
  • Setx writes variables to the master environment in the registry. Variables set with setx variables are available in future command windows only, not in the current command window.
  • HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE are the only supported hives. REG_DWORD, REG_EXPAND_SZ, REG_SZ AND REG_MULTI_SZ are the valid RegKey data types.
  • When gaining access to REG_MULTI_SZ values in the registry, only the first item is extracted and used.
  • You cannot use setx to remove values added to the local or system environments. You can use set with a variable name and no value to remove a corresponding value from the local environment.
  • REG_DWORD registry values are extracted and used in hexadecimal mode
  • File mode supports the parsing of CR-LF text files only.
