This software will automatically re-create your windows registry while omitting the junk entries. In addition to compressing, the Registry Compressor Pro has Backup and Restore functionality to make maintaining a healthy registry trouble free. Windows ME users must use Registry Compressor ME. Version 2.0 can be installed in a long filename folder, automatically detects the Windows directory, has 10 trial uses instead of 5 and should be more compatible than previous versions.
