windows username , UID , user profile , SID

UID
user's profile id
user identifier
I donno how to call it under windows, it is the folder name for each user's own settings

*, key name, under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

quite useful if you want to edit specific user's registry settings, you don't need to logon that user's desktop / session and edit the HKCU\
now get the user name and UID and edit it under the HKEY_USERS\UID

SID, binary value, under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
