The Windows Registry grows as data is added to it, but it never shrinks when data is removed. A bloated registry with a lot of empty space can slow down the boot time as well as performance. Registry Defragmenter and Compactor will rebuild and re-index your registry to eliminate structural mistakes and corruption.

• Repairs defects by rebuilding your registry.
• Remove fragmentation with a linear and sequential registry.
• Compact registry by removing gaps and unused space.
• Improve system performance due to faster registry load/read.
• Protect privacy by erasing previously deleted registry cells.
