How do you find the current user in a Windows environment?

Question

You can use the username variable: %USERNAME%

Username:

echo %USERNAME%

Domainname:

echo %USERDOMAIN%

You can get a complete list of environment variables by running the command set from the command prompt.

Just use this command in command prompt

C:\> whoami

It should be in %USERNAME%. Obviously this can be easily spoofed, so don't rely on it for security.

Useful tip: type set in a command prompt will list all environment variables.

%USERNAME% is the correct answer in batch and other in Windows environments.

Another option is to use %USERPROFILE% to get the user's path, like C:\Users\username.
