Quick FAQ:

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.

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.
RegSaveKey function

Here is what Microsoft had to say about this topic:

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.

Using the Volume Shadow Copy instead of the RegSaveKey API makes this registry backup program safer.

Special thanks to AHDesign91 for using the registry icon for the program.

Tweaking.com – Registry Backup Change Log


  • Updated controls, bug fixes, and code changes.


  • Updated ManageACL_32 and ManageACL_64 to v1.5.0
  • Fixed and adjusted multiple areas of the user interface to handle better systems with high DPI enabled. Many new laptops are coming with HD screens with a large resolution, so their DPI is set very high to make programs and text readable. When this increase in DPI was set, many parts of the program didn’t draw correctly. A few areas still need adjusting, but all the major ones have been fixed.
