Ainvo Registry Defrag v4.2.7.2105

Ainvo Registry Defrag is a tool that claims to defragment the Windows registry.

While there can be a performance gain from defragmenting registry hive files themselves (which must be done before Windows boots up properly), there is really no evidence that other registry clean-up tools really lead to much of a performance increase in Windows, if any.

Still, the tool is free to use if you want to try it.
