How to fix "running scripts is disabled on this system"?

When I try to run ionic commands like ```ionic serve``` on the VS Code terminal, it gives the following error.

How can I fix this?

```none
ionic : File C:\Users\Lakshan\AppData\Roaming\npm\ionic.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see

This is because of Execution Policy. This defines how powershell scripts will run.

In Default windows desktops, it is Restricted, not allowing any scripts (signed or unsigned) only interactive sessions.

So best is you set using `RemoteSigned` (Default on Windows Server) letting only signed scripts from remote and unsigned in local to run, but `Unrestriced` is insecure lettting all scripts to run.

To set run `Set-ExecutionPolicy -ExecutionPolicy RemoteSigned` as administrator.

To Bypass this you need to change the Execution policy.
Type this into your terminal.
```
Set-ExecutionPolicy -Scope CurrentUser
```
then it will prompt you to supply a value at which point you can set Bypass / RemoteSigned or Restricted.
```
cmdlet Set-ExecutionPolicy at command pipeline position 1
Supply values for the following parameters:
ExecutionPolicy: "RemoteSigned" or "Bypass" or "Restricted".
```

This code will fix it:
```
Set-ExecutionPolicy RemoteSigned –Scope Process
```

I found a way to fix this error.

It is as follows:

1. First, **Open PowerShell** with **Run as Administrator**.
1. Then, run this command in PowerShell
```none
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
```
1. After that type ```Y``` and press Enter.
