If you're interested to try out the latest C++26 options: The Windows port for GCC 15.1 is available for download.
I installed GCC 15.1.0 (with POSIX threads) + MinGW-w64 13.0.0 UCRT - release 2. To install, download the zip file, and extract somewhere as administrator.
If you want, you can add its bin directory to your path. But many IDEs (Eclipse, VSCode, CLion, ...) and build tools don't require that.
