Why do you need defrag registry?

During the normal operation of a Windows system, registry data is constantly being written to and removed from the registry. Over time this data becomes scattered within the registry file and when information is deleted from the registry holes are left which fragment the data within the registry. Registry compacting optimizes your registry by removing gaps and wasted space, thus improves the whole system performance.

Registry compacting/defragging optimizes your registry by removing gaps and wasted space in Windows registry files.
