The question is about the FIB side of the equation. It’s not an anti-windows remark it’s just a question since I’ve never done full tables on Windows and I don’t know it to be a supported use case. The BGP feature in Server versions is intended for cloud gateway not internet. Even the Linux kernel takes some parameter tuning to gracefully receive a full table without complaints. It’s a million routes in systems which typically have less than 10 after all.
