s a useful Security feature.
Incidentally, mention must also be made of another new technology underlying Vista : The Kernel Transaction Manager, which enables Transactional Registry. This feature enables a sort of a registry rollback. But it’s not implemented in Registry Editor. Instead, this feature is designed for use by developers who need to create robust applications using transactional processing.
How To Edit The Registry.
The primary tool in Windows Vista / 7 for working directly with the registry is Registry Editor. To access it, simply type regedit in Vista's Start Menu Search Bar and hit Enter ! You have to be doubly careful when working with the Registry, as there is no confirmation prompt or a click OK to save prompt. Changes made are directly incorporated.
Mention must specifically be made of
HKEY_LOCAL_MACHINE\System\CurrentControlSet
hive as the keys in this particular are so essential for Vista to start-up, that its backup is maintained, which you can restore when necessary, simply by booting in Safe Mode and selecting Last Known Good Configuration.
