Solution for setting environment variables in Windows without restarting the system

When operating a Windows server, this problem is often encountered. to deploy the service, you need to add environment variables. However, some variable information related to DLL calls takes effect only after Windows is restarted, if the server cannot be restarted at will, use the following method.

For example, after the environment variable XXX_SERVER_HOME = C:/TEMP is set
Open a CMD window and enter set XXX_SERVER_HOME = any command to close this CMD window.
The previously configured variable values in the environment variables will take effect.
The input variable value in the CMD window is a temporary variable and does not affect the configured variable value.
