set environment variable from batch
DDK
When I set a environment variable envir using setx command, It seems to not actually 'set' in environment.
setx envir "windows"
if 1==1 (
setx envir "unix"
)
echo %envir%
set
The set command displays a list of environment variable but it doesn't display the variable which was currently set by the previous line.

In your example, the environment variable %ENVIR% is set to "windows". This is stored in the user-specific environment variables in the Windows registry. The change is not directly reflected in the environments of currently active processes.
To actually see this new setting via set command, you have to open a new command box using cmd.exe. The current command box does not automatically re-read changed settings from the registry. You could also use the system control SYSTEM and look under Extended Properties / Environment:
