Setting value of "" empty quotes will appear to delete the variable - it's not shown by SET but the variable name will remain in the registry. The CMD shell will fail to read an environment variable if it contains more than 8, characters. The Command Prompt will also ignore any environment variables that are inherited from a parent process if they are longer than characters. Setting environment variables equal to a simple string is the most basic and common usage of SetX.
