On our Windows servers we have Posh-ACME and use DNS validation for our domains via plugin against our Windows DNS servers. https://poshac.me/docs/latest/

We use scripts for provisioning, including IIS bindings, and a scheduled task for renew --

We've also used Posh-ACME with Cloudflare hosted DNS and it worked well. The module has multiple DNS plugins for handling semi-automated validation and renewals as needed.

Settled with the Certify the Web. Works great.

I use simple-acme (formally win-acme) on all my servers and it works great.

I'm using win-acme, it's more cli oriented but works like a charm.
