How to modify the Windows 7 environment variable

When using the computer
to run certain applications, you need to modify the system environment variables. For example, when installing JAVA, we need to configure the system environment variables. So what is an environmental variable? Environment variables generally refer to some parameters used in the operating system to specify the operating system operating environment, such as temporary folder location and system folder location. This is similar to the default path of the DOS period. When you run some programs, in addition to looking in the current folder, you will find it in the default path set. Simply put, "Path" is a variable that stores the directory path where some common commands are stored. Here we will tell you about how to modify environment variables under Windows 7.
Click “My Computer”, select properties. Find and open “Advanced System Configuration”. In the next page, click “Advanced System Configuration” to open the “System Properties” window. Find the <quo;Environment Variable" button and click. Environment variable window. There are generally two variables in the environment variable window, one is the user-specific environment variable that you are currently using, and the other is a system variable that all users can access. In fact, if you only use one user on your computer, the effect will be the same regardless of the user's environment variable or system variable. In order to prevent other users from being created in the future, I suggest you modify the system variables instead of a user-specific environment variable. Find the variable path in the system variable display box, select it and click Edit to modify it. The path variable tells the system that when the system is required to run a program without telling the full path of the program, the system should look for the program in the current directory instead of the directory specified by the path variable. Generally, when we modify the environment variable, if we do not specify a specific variable, such as JAVA_HOME, the environment variable we refer to is path. Note that after the modification is completed, you must remember to click “Delete” to save the modified content. Remember to separate each path between another path and another path. In addition, if you feel in the window editing system variables not make changes, you can put the contents into the path of copy text documents to find and modify, and then paste back
