To create an environment variable it is necessary to have administrator privileges, so just use the command setx

Example:

setx NOME valor

  • And if I want to delete this variable in the future, which command do I use?

  • Thanks @rray :)

  • @Laércio Lopes REG delete HKCU Environment /F /V NAME removes the variable.. more details on that reply
