HKEY_LOCAL_MACHINE\SOFTWARE\Classes and HKEY_CLASSES_ROOT
Even there is registry hive HKEY_CLASSES_ROOT then what is the need of HKEY_LOCAL_MACHINE\SOFTWARE\Classes registry hive? What is the need of having duplicate entry?

HKEY_CLASSES_ROOT combines both HKLM\Software\Classes and HKCU\Software\Classes
So on one hand it combines per-machine and per-user registrations, and also it's there to provide a merged view for older applications (16 bit)

If HKEY_CLASSES_ROOT is having both HKCU and HKLM entries then what is the need of having the HKLM\Software\Classes and HKCU\Software\Classes hives? we can use only HKEY_CLASSES_ROOT rt? - Mallikarjun 10 years ago

yes, you can use HKCR
But HKCR is in fact an ad-hoc combination of HKCU\SOFTWARE\Classes and HKLM\SOFTWARE\Classes. It does not exist without the 2 others. It gets populated when a user logs in but is not really something that exists in and of itself.
