You can choose to download the binary file of the latest version of golang. For ease of installation, I chose to download the Windows 64-bit version, just click on the corresponding version to download.

After downloading, you will get an msi file named "go1.16.5.windows-amd64.msi". Next run it and follow the prompts to install. Note, before starting the installation, please make sure to close any running VSCode, PowerShell or other golang-related applications.

Step 2: Configure environment variables

When you complete the installation of golang, you need to add the path to golang in the Windows environment variables. This way you can use golang in any directory.

First, press the Win R key to open the "Run" window. Here, enter the "control" command to open the "Control Panel". In the Control Panel, select "System and Security", "System", find the environment variables in the right panel and click on it.

In the pop-up window, find the "Path" variable under "System Variables" and double-click it to open it.

Click New, reopen a blank row, and copy the golang installation path to the new row. In my example, the path where golang is installed is "C:Go in".

After completion, you should see the environment variables window like this:

This completes the configuration of the environment variables.

Step 3: Verify whether golang is configured correctly

Now, you need to verify whether golang is configured correctly. For this, you can use Windows command prompt, or PowerShell, or any golang editor. In this article, we will use Windows command prompt to verify the installation and configuration of golang.

Press the Win R key to open the "Run" window. Enter the command "cmd" to open the Windows command prompt.

At the prompt, enter "go version". If you see output like the following, it means that golang has been successfully installed and configured.

If you see output similar to "'go' is not recognized as an internal or external command, operable program or batch file.", it probably doesn't exist. Configure the environment variables correctly. Please go back to step 2 to check whether the environment variables are configured correctly.
