windows 10 how to force the edge browser to use TLS1.2?

Question

HI All,

How do I force the browser to use TLS 1.2? Currently, Edge and Chrome are both accessed by default 1.0, and the packet capture and analysis is performed through Wireshark.
```Looking forward to hearing from you.

It's normal for me to use fildder to access, the default will use tls1.2, if I exit fildder and only use edge or chrome to access, then the client will use tls1.0 for access.

Disable TLS 1.0 and 1.1. Follow https://support.microsoft.com/en-us/topic/kb5017811-manage-transport-layer-security-tls-1-0-and-1-1-after-default-behavior-change-on-september-20-2022-e95b1b47-9c7c-4d64-9baf-610604a64c3e

Hi,

Thanks for your post. Based on my research, if you would like to force the Edge to use TLS 1.2, you can follow the steps:

1. From Start Menu > Open 'Internet Options' Options > Advanced tab.
2. Scroll down to the Security category, manually check the option box for Use TLS 1.2 and un-check the option box for Use TLS 1.1 and Use TLS 1.0.
3. Click OK.
4. Close your browser and restart MS Edge.

For Chrome force steps, please contact Chrome support.

Best Regards,

Ian Xue
