PowerShell add Windows PATH variable using setx

PowerShell add Windows PATH variable using setx.

Run Powershell as Administrator

setx /M PATH "$Env:PATH;"

To verify

$Env:PATH

NOTE: Dans les fenêtres 10 unless ‘/m’ is the very first argument rather than the last, the variable is set in the logged-in user’s context not the machine’s.

Remarks

• Le Setx command is similar to the UNIX utility SETENV.
• Setx provides the only command-line or programmatic way to directly and permanently set system environment values. System environment variables are manually configurable through Panneau de contrôle or through a registry editor. Le ensemble commande, which is internal to the command interpreter (Cmd.exe), sets user environment variables for the current console window only.
• Vous pouvez utiliser le setx command to set values for user and system environment variables from one of three sources (modes): Command Line Mode, Registry Mode, or File Mode.
• 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 et 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 you gain access to REG_MULTI_SZ values in the registry, only the first item is extracted and used.
• You cannot use the setx command to remove values that have been added to the local or system environments. You can use ensemble 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 carriage return and line feed (CRLF) text files only.
