Assalamualaikum, Hi @Balamir can it detect win 11?

Assalamualaikum, Hi @Balamir can it detect win 11?

Windows 11 falls under Windows 10 at this moment since both share the same NT version.
So I would just change "Windows 10" to "Windows 10/11"

When Windows 10 was released, the NT version was 10.0 to have the same NT version as the Windows version. Now we are with Windows 11 and the NT version is still 10.0
