Over time the registry becomes larger and larger, it leads to errors and poorer system performance. This is because the data will be marked as blank but remains in place. In this way the registry becomes more and more fragmented over time. Registry fragmentation causes overall system performance to decrease.
Registry Defrag 2010 is a registry de-fragmentation tool that:
Optimizes registry by removing Fragments, Gaps and wasted space in registry files.
Use registry map to evaluate the condition of the registry.
De-fragmentation level is analyses before you start de-fragmentation process.
