Greetings, All!

Been doing some housekeeping in my Cygwin installation at work, and wanted to
change the owner of the files to something other than myself.
TrustedInstaller seemed like a good neutral target, but it took me a little
while to find out it is

1. …named "NT SERVICE+TrustedInstaller" actually (which is predictable
somewhat);
$ getent passwd | grep -i trust
NT SERVICE+TrustedInstaller:*:328384:328384:U-NT SERVICE\TrustedInstaller,S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464:/:/sbin/nologin

2. …can not be accessed by any other name (unlike "NT AUTHORITY\SYSTEM");
$ getent passwd System
system:*:18:18:U-NT AUTHORITY\system,S-1-5-18:/home/system:/bin/bash
$ getent passwd 18
ñèñòåìà:*:18:18:U-NT AUTHORITY\ñèñòåìà,S-1-5-18:/home/ñèñòåìà:/bin/bash

3. …can not be accessed by ID! Which is rather surprising.
$ getent passwd 328384
[2] <- user not found

Is this some special case of some kind of Windows' kinks?
