Commands in blog entry don't work

The operating system is Windows 7 Version 6.1 Build 7601 SP1.
According to blog post [Removing Support For Old TLS Versions On The Chocolatey Website](https://blog.chocolatey.org/2020/01/remove-support-for-old-tls-versions/), is possible to find out which protocols are being used and add TLS 1.2 explicitly. However it doesn't work:

```
Windows PowerShell
Copyright (C) 2009 Microsoft Corporation. All rights reserved.

PS C:\Windows\system32> [Enum]::GetNames([Net.SecurityProtocolType]) -contains 'Tls12'
False
PS C:\Windows\system32> [Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12
PS C:\Windows\system32> [Enum]::GetNames([Net.SecurityProtocolType]) -contains 'Tls12'
False
PS C:\Windows\system32> [System.Net.ServicePointManager]::SecurityProtocol.HasFlag([Net.SecurityProtocolType]::Tls12)
Method invocation failed because [System.Net.SecurityProtocolType] doesn't contain a method named 'HasFlag'.
At line:1 char:59

```

PowerShell info:
```
PS C:\Windows\system32> $PSVersionTable

Start with the linked “Removing Support For Old TLS Versions On The Chocolatey Website” blog entry and compare its commands with the reported Windows 7 PowerShell 2.0 output. Reproduce the commands in that environment if available; done means the documentation accurately explains whether the commands work and what users should do.
