Editing Windows Registry (section)

====HKEY_CLASSES_ROOT (HKCR)====
:Abbreviated HKCR, HKEY_CLASSES_ROOT contains information about registered applications, such as [[file association]]s and [[Object linking and embedding|OLE]] Object Class IDs, tying them to the applications used to handle these items. On [[Windows 2000]] and above, HKCR is a compilation of user-based {{code|HKCU\Software\Classes}} and machine-based {{code|HKLM\Software\Classes}}. If a given value exists in both of the subkeys above, the one in {{code|HKCU\Software\Classes}} takes precedence.<ref>{{cite web| URL = http://support.microsoft.com/kb/256986 | title = Description of the Microsoft Windows registry | access-date = 2008-09-25 }}</ref> The design allows for either machine- or user-specific registration of [[Component Object Model|COM]] objects.<!-- The user-specific classes hive, unlike the HKCU hive, does not form part of a roaming user profile. -->
