sms: how is the guid generated? by Microsoft Windows NT

i thought i'd locality conventionally this over i've not seen anything written forth the subject (or maybe my Yahoo skills wish honing). anyway, compromising to the clientidmanagerstartup.roster, it evaluates these three elements:

• smbios
• sid
• hwid

as well, it looks pertinent hwid is a computed account based forward these five fields:

• win32_systemenclosure.serialnumber
• win32_systemenclosure.smbiosassettag
• win32_baseboard.serialnumber
• win32_bios.serialnumber
• win32_networkadapterconfiguration.macaddress
