Can we write a C# code to automatic tick "Use TLS 1.2"?

This is manual step:- Go into Internet Options > Advanced then down to the Security section, and tick the box for "Use TLS 1.2".

Is there any way to tick it programmatically in C#.

  • Most of those are Reg key. you can simply modify them with win32 or executing them in a command shell. – xdtTransform May 23 '19 at 11:49

  • Btw some of the reg key name may depends on the Windows version or patch. and may differ from the one in the MSDN. – xdtTransform May 23 '19 at 11:57

Use UI Automation Test Library from microsoft. It's used for testing purpose but it can work here. https://learn.microsoft.com/en-us/windows/desktop/winauto/ui-automation-test-library

Most of Internet option are Reg key. You can simply modify them with win32 or executing them in a command shell.

The key is specified in this MSDN article 1. and 2

Now either "How to modify registery key in C#" or "How to execute cmd command in c#".
