Calling SetEnvironmentVariable has no effect on the system environment variables. This allows applications, such as the shell, to pick up your updates. The maximum size of a user-defined environment variable is 32, characters.
There is no technical limitation on the size of the environment block. However, there are practical limits depending on the mechanism used to access the block. For example, a batch file cannot set a variable that is longer than the maximum command line length. Windows Server and Windows XP: The maximum size of the environment block for the process is 32, characters. Starting with Windows Vista and Windows Server , there is no technical limitation on the size of the environment block.
The GetEnvironmentVariable function determines whether a specified variable is defined in the environment of the calling process, and, if so, what its value is. To retrieve a copy of the environment block for a given user, use the CreateEnvironmentBlock function. To expand environment-variable strings, use the ExpandEnvironmentStrings function. Resolved my issue. Clear instructions. Easy to follow. No jargon. Pictures helped. Didn't match my screen. Incorrect instructions.
Too technical. Not enough information. Not enough pictures. Any additional feedback?
