Emacs doesn't up-case the system-name, it uses the exact string we get
from the system API we use to get the machine name (GetComputerName).

Patches to use other APIs that perhaps don't have this issue, without
incurring disadvantages (like the possible hangs if DNS is not
available etc.) are welcome.
