Registry fragmentation is a similar phenomenon as fragmented hard drives, Your Windows registry can become fragmented over time, occupying more space on your hard disk than necessary and decreasing overall performance. Especially when many programs are installed and uninstalled. When programs and other components are removed from the system they can leave behind data inside the registry. After data is deleted from the registry, the space in the file used by that data is kept until it can be re-used by newly added data. If lots of very small bits of data are deleted the registry can become very bloated with ‘holes’ where no data will fit. This causes the registry to be larger than necessary which in turn means it is spread over more hard drive space and hence slower to access.
Registry Defrag analyzes the structure of your registry and rebuilds it completely from scratch. thus removes any slack space that may be left from previously modified or deleted keys. The registry is defragmented, and any structural errors are corrected. By defragging your registry, it will create a more linear structure maximizing application response times and registry access times, saving memory, and enhanced boot-up times. This can greatly improve system performance and to avoid system crashes and the loss of data.
Registry Defrag involves the following steps:
1. Registry Defrag will check how fragmented your registry is. Before the analysis starts, you will be informed that all other applications must be closed. Please follow these instructions and close all other applications before you continue. You should do so because any changes made to the registry after Registry Defrag has been run are lost after the reboot.
2. You will be able to view the fragmentation report. If there is potential for optimization, you will be told by how many percent and kilobytes the size of the registry can be reduced.
3. Registry will be defragmented and compacted. Registry Defrag must restart your computer for this.
