What The Windows Vista Registry Is All About!
The Windows registry of any Windows Vista Computer is a directory containing all the options and settings set up on that particular PC.

The HKLM key contains all of the information that has something to do with the hard ware and the soft ware currently installed in your computer, while the information on user accounts implemented on your computer is saved in the HKU key.
The HKCR hive contains information that concerns filetypes, extensions, URL protocol prefixes, and registered classes. All the data in the HKCR key is taken from these 2 keys”HKLMSOFTWAREClasses and HKCUSOFTWAREClasses. If both keys contain duplicate information, it is there in the HKCR. But if there are conflicting data in the two keys, then only the data in the HKCUSOFTWAREClasses is shown in the HKCR.

Details like desktop settings, environment variables, available printers, folders and Control Panel configurations for the user currently logged on is shown in this hive.
