While Windows has become the unchallenged and authoritative entity for the operating system, you perhaps do know that you need to get registered when you do start working on your system. The Windows Hive groups several keys and sub keys and ensures that your registration backs up the data in the Windows Hive. The hive contains a set of supporting file systems so that the data is stored in back up necessarily. The tag to the file name in the hive indicates the type of data the file contains! Quite sophisticated, is it not? No wonder we cannot live without Windows!
