Getting unique ID of a user's machine

I haven’t really keep up with this thread, but I recall seeing wmic, shell redirection, MAC Address, Drive SerialNumber, etc. Old code, revised a bit for this, only tested on Win7 & SU2017.

Maybe Win32Ole? If that’s okay, try the following:

# load '<path to this>'

require 'win32ole'

locator = WIN32OLE.new("WbemScripting.SWbemLocator")
wmi = locator.ConnectServer(".", "/root/cimv2")

adapters = wmi.ExecQuery("Select * from Win32_NetworkAdapterConfiguration")
drives   = wmi.ExecQuery("Select * from Win32_DiskDrive")

ctr = 0 ; item0 = nil


puts "\n#{'-' * 20} Adapter Info"
adapters.each { |net|
  if net.MACAddress
    item0 = net if ctr == 0 ; ctr += 1
    puts "#{net.MACAddress} #{net.IPEnabled.to_s.ljust(6)} #{(net.IPAddress || []).join('  ')}"
  end
}

if item0
  puts "\n#{'-' * 20} Adapter Properties"
  item0.properties_.each { |prop| puts prop.Name }
end

ctr = 0 ; item0 = nil

puts "\n#{'-' * 20} Drive Info"
drives.each { |drv|
  if drv.SerialNumber
    item0 = drv if ctr == 0 ; ctr += 1
    puts "#{drv.SerialNumber.strip.ljust(20)}  #{drv.Description.ljust(20)} #{drv.InterfaceType}"
  end
}

if item0
  puts "\n#{'-' * 20} Drive Properties"
  item0.properties_.each { |prop| puts prop.Name }
end
