I have a BIOS machine which is dual boot Windows 7/Fedora 22. I just upgraded Windows from 7 to 10, but grub2 still detects it as "Windows 7 (loader)", same as before, even after running "grub2-install /dev/sda" and "grub2-mkconfig -o /boot/grub2/grub.cfg" in F22. Other than the mislabel, everything seems fine. Is it normal for grub2 to not detect the correct Windows version? What about Windows 8, which has been around for a while?

I'm pretty sure this is hard coded in GRUB. There is nothing that GRUB finds that identifies the version. Perhaps the most appropriate thing is to get a patch that just says "Microsoft Windows" to upstream.

I have two other BIOS machines that are also dual-boot Windows and F22 (one is XP and the other is Vista) and grub2 detects them correctly as "Microsoft Windows XP Home Edition" and "Windows Vista (loader)", resp. I don't know if something changed in Windows 8 and later, or if it has to do with my W10 machine being an upgrade from W7, as opposed to the clean install I normally do. (I could clean install it, since W10 should reactivate automatically, but it's not worth the trouble for now.)

This looks like BIOS bootloader recognition with two distinctions: Windows NT/2000/XP (loader) Windows Vista/7 (loader)

This might be the one for EFI, but I can't tell how it distinguishes between them.
Windows\ Vista*|Windows\ 7*|Windows\ Server\ 2008*)
Interesting. After upgrading from W7 to W8.1, I had 'Windows 8 (loader) (on /dev/sda1)'. However, After installing W10 Tech Preview 10130 and upgrading to the actual release, I have 'Windows 7 (loader) (on /dev/sda1)'
