Proposal: Default to Windows Automatic Root Certificates Update for Improved User Experience

[solarispika]

Hi @yhirose,

Following up on the discussion in https://github.com/yhirose/cpp-httplib/issues/1431#issuecomment-2476060561, I wanted to propose enabling Windows Automatic Root Certificates Update as the default behavior for cpp-httplib on Windows. This feature would enhance user experience by leveraging the latest system root certificates automatically, reducing the need for users to manually manage certificates.

Currently, users can achieve this functionality by setting a custom verification callback, but making it the default on Windows would streamline the setup and make cpp-httplib more convenient out of the box. Additionally, this default change could allow us to skip preloading system root certificates during client construction, minimizing initialization overhead and potentially improving performance.

Would love to hear your thoughts on this proposal, and whether you see it aligning with the project’s direction.

Thank you!
