You can use RegEdit to export the following two keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

HKEY_CURRENT_USER\Environment

The first set are system/global environment variables; the second set are user-level variables. Edit as needed and then import the .reg files on the new machine.

Here is my PowerShell method  gci env     sort-object name   Where-Object     Name -like  MyApp      Foreach    System Environment   SetEnvironmentVariable       Name          Value     Machine       What it does   Scoops up all environment variables Filters them Emits the formatted PowerShell needed to recreate them on another machine  assumes all are set at machine level    So after running this on the source machine  simply transfer output onto the target machine and execute  elevated prompt if setting at machine level

My favorite method for doing this is to write it out as a batch script to combine both user variables and system variables into a single backup file like so  create an environment-backup bat file and put in it    echo off    RegEdit can only export into a single file at a time  so create two temporary files  regedit  e   CD  environment-backup1 reg   HKEY CURRENT USER Environment  regedit  e   CD  environment-backup2 reg   HKEY LOCAL MACHINE SYSTEM CurrentControlSet Control Session Manager Environment      Concatenate into a single file and remove temporary files  type   CD  environment-backup1 reg    CD  environment-backup2 reg   gt  environment-backup reg del   CD  environment-backup1 reg  del   CD  environment-backup2 reg    This creates environment-backup reg which you can use to re-import existing environment variables  This will add  amp  override new variables  but not delete existing ones

I would use the SET command from the command prompt to export all the variables  rather than just PATH as recommended above  C   gt  SET  gt  gt  allvariables txt  To import the variablies  one can use a simple loop  C   gt  for  F  A in  allvariables txt  do SET  A

You can get access to the environment variables in either the command line or in the registry   Command Line  If you want a specific environment variable  then just type the name of it  e g  PATH   followed by a  gt   and the filename to write to  The following will dump the PATH environment variable to a file named path txt   C   gt  PATH  gt  path txt   Registry Method  The Windows Registry holds all the environment variables  in different places depending on which set you are after  You can use the registry Import Export commands to shift them into the other PC   For System Variables    HKEY LOCAL MACHINE SYSTEM CurrentControlSet Control Session Manager Environment   For User Variables   HKEY CURRENT USER Environment
