How to completely disable PowerShell 2.0 in Windows 10

Microsoft is pushing most people to use PowerShell instead of the old Command Prompt. The main reason is that PowerShell is much more feature-rich and powerful than the regular Command Prompt.

1. How are Command Prompt (cmd) and PowerShell different?

By default, any user can launch and use PowerShell directly from the Command Prompt or from File Explorer. Overall, PowerShell has different versions. As of the time of writing, PowerShell v5 is the latest version.

However, for compatibility reasons, Windows still activates the old PowerShell 2.0. As an older version, PowerShell 2.0 is deprecated and is even considered a security risk.

So, unless you really need PowerShell 2.0, you shouldn't turn it off completely. Follow the steps below to completely disable PowerShell 2.0 in Windows 10.
