Note that all recent/current versions of the Windows Time Service are
in fact SNTP/NTP implementations, with quality of implementation
improving in newer versions.
Old (now unsupported) versions of the Windows Time Service violated the
SNTP/NTP specification in ways that required special workarounds in
standard NTP servers. Even older implementations that didn't even
include a service named "windows time service" used simplistic time
queries over the SMB protocol.
Besides being included with the OS, the "windows time service"
typically defaults to imposing a much lower load on the selected time
source, by using much longer poll intervals. In "Active Directory"
(Windows 2000 and later) setups, there is also a dead simple automatic
configuration, where each machine simply syncs against it's nearest
"upstream" in the authentication/management hierarchy, limiting
practical management work to machines that have no such "upstream",
such as the 2 to 4 machines at the top of the tree. And of cause
machines needing more precise time than needed by the basic Windows
