Windows 10: No TLS 1.2 support on fresh Windows 11 24H2

I have used the official mediacreation tool to create an usb stick and installed Windows 11 24H2. I notice TLS 1.2 support is completely lacking. The registry entries are simply not there. This causes SSL handshake failures in outlook with some mailservers. How do I install TLS 1.2 on the operating system level, most guides are aimed towards browsers.

Microsoft Edge TLS Security

After trying everything (not a lot of steps) listed in the Microsoft Edge support site, I did a wider search and found this very simple youtube video that fixed it immediately:

For those who prefer not to click links the steps are simple:

1. Click in the Cortana search bar next to the Win 10 Start button

2. Type internet options

3. Select internet options (control panel) from the list

4. Click on the advanced tab

5. Scroll down to the security section

6. Make sure the following are all clicked:
Use SSL 3.0
Use TLS 1.0
Use TLS 1.1
Use TLS 1.2

7. Click apply

8. Refresh the page that was giving the error and it should now connect.

Hope this helps, it was a 30 second fix after hours of pounding my head against the error with the Support site suggestions.

 

Factory reset Windows 11 24H2 (build 26100.863)

Hi, I am Dave, I will help you with this.

There are no currently listed problems resetting version 24H2 of Windows 11 and no specific steps you need to perform, are you experiencing any problems with that insider build that is causing you to perform a Windows reset?

 

TLS 1.0 and TLS 1.1 support will be discontinued on September 24, 2020
