====HKEY_CURRENT_USER (HKCU)====
:Abbreviated HKCU, HKEY_CURRENT_USER stores settings that are specific to the currently logged-in user.<ref>{{cite web| url = https://technet.microsoft.com/en-us/library/cc976337.aspx | title = HKEY_CURRENT_USER | year = 2009 | publisher = [[Microsoft]] | access-date = 2009-04-08 }}</ref> The HKEY_CURRENT_USER key is a link to the subkey of HKEY_USERS that corresponds to the user; the same information is accessible in both locations. The specific subkey referenced is {{code|(HKU)\(SID)\...}} where (SID) corresponds to the [[Windows SID]]; if the "(HKCU)" key has the following suffix {{code|(HKCU)\Software\Classes\...}} then it corresponds to {{code|(HKU)\(SID)_CLASSES\...}} i.e. the suffix string "_CLASSES" is appended to the (SID).

:On Windows NT systems, each user's settings are stored in their own files called NTUSER.DAT and USRCLASS.DAT inside their own Documents and Settings subfolder (or their own Users sub folder in Windows Vista and above). Settings in this hive follow users with a [[Roaming user profile|roaming profile]] from machine to machine.
