@DubioserKerl @bagder libc versions on Windows are actually a part of the compiler instead of a fundamental system component like on Linux. This means the MSVC version you use determines the libc version you ship (either statically linking it, or relying on those VC++ redistributables).
This is actually a good thing compared to Linux, because it allows cleaner separation between modules. This is a problem for Flatpak etc on Linux wrt graphics drivers.
