FAQ: How to Set Up KUBECONFIG on Windows [WISE-PaaS/EnSaaS K8s Service]
1. Download config file from the Management Portal
Save the config file to the .kube folder under the user's home directory %HOME%.kube.
For example: C:\Users{YourAccount}.kube.

2. Set up the system environment variable KUBECONFIG
Open System Properties. Click Environment Variables.

3. Under System Variables
If you don't see any variable called KUBECONFIG, click New to create one. If you do have the variable, select the variable and click Edit.

4. Add or append the file path of the new config file.
Note that you need to enter the exact full path for the config. %HOME% will not work for this setting.

5. Verify the new config.
Type kubectl config view. You should see the new cluster name in the output.

Unfortunately your tips didn't help me. So I provide PS command for merging configs in Win10.
PS ~\.kube> $Env:KUBECONFIG=("%Path to first config%\config1;%Path to second config%\config2") PS ~\.kube> kubectl config view --merge --flatten | Out-File "%Path where your merged config will be placed%\new_config"
