Q: Does Tweaking.com - Registry Backup support Windows 2000 or older?
A: The program only supports Windows XP and newer because older versions don't have the volume shadow copy service. For older operating systems I recommend my old favorite Erunt. Download - http://majorgeeks.com/Erunt_d1267.html
Q: Why does the program use the Volume Shadow Copy Service instead of the RegSaveKey API like Erunt and others?
A: Microsoft recommends using the Volume Shadow Copy to backup up the registry. This grabs a complete backup of the registry hives as they are.
Quote From Microsoft:
"Applications that back up or restore system state including system files and registry hives should use the Volume Shadow Copy Service instead of the registry functions."
"Using RegSaveKey together with RegRestoreKey to copy subtrees in the registry is not recommended. This method does not trigger notifications and can invalidate handles used by other applications."
By using the Volume Shadow Copy instead of the RegSaveKey API this registry backup program is safer to use.
