Registry Compressor for Windows 9X/NT/ME/2000/XP will enhance your system's performance by removing registry gaps and empty entries, and then compressing and defragmenting the registry file.
Microsoft Windows® includes no tool to perform this function!
Why do you need Registry Compressor?
Over time the registry becomes larger and larger as new programs are installed, used and removed.
The design of the registry is such that when you add some data into the registry it becomes larger, but when you remove this data the registry will not shrink back to its previous size. Why?
When a registry entry is removed, that entry is simply marked as blank but remains in place, introducing a gap into the registry. In this way the registry becomes more and more fragmented over time.
