I am using windows xp machine for application development. I use TLS 1.0 but I have to enable TLS 1.2. I have added it in registry and set tls 1.2 enable = 1. When I run the application it throws SSL security error. I have also downloaded the KB4019276 file. What else can I do?

    Windows XP is extremely outdated and there never was support for TLS 1.2. Referenced KB doesn't apply to Windows XP and will not work. The only way to get TLS 1.2 support is to upgrade to OS version where it is supported. The lowest client operating system is Windows 7, which is out of support too.

    I shared a solution step, May it help you.

    1. open the command prompt.
    2. write down: hostname
    3. Again write down: whoami [ note: please open command prompt by administrator credentials)
    4. regiedit

    1. User's image
    2. if hex value 1, that means TLS version 1.2 is enabled.
    3. If the hex value is 0, that means TLS version 1.2 is disabled.
