• Any other interesting things about your environment that might be related
  to the issue you're seeing?

I tried this with a clean install.

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

PowerShell 7.4.6

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

Ran the installer

• What did you expect to occur after running these commands?

Despite this line https://github.com/git-for-windows/build-extra/blob/6735402549b1776f65723e129b9208fa0ee5056b/installer/install.iss#L2331 and the commit that says it should be default, the default when clean installing still seems to be OpenSSL.

• What actually happened instead?

The default on a clean install of Git for Windows is still OpenSSL instead of schannel despite what the code of the installer suggers

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?
