Windows uses the term 'domain' to mean something more than just DNS
domain.  All versions of Windows are aware of DNS domains;  it's the
other kind they upsell.

Your router is almost certainly sending .home as the DNS domain in its
DHCP response.  Windows is appending it on bare-hostname lookups because
it was told by its DHCP server that it is part of the .home DNS domain.
