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.

Features 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.
