Registry Tune is the program for set-up Windows (9x, NT and so on) by modifying the registry. With help of RegTune you can also change settings of many other programs without run its. The program stores information about registry keys, parameters, their types and comments as a tree. The advantage of the program as against same other, is that the experienced user itself can add the new Windows settings experienced by him or found in Internet, can change already existing one, or can remove it at all. The program is completely transparent, i.e. when you change either key or parameter of the registry, you can see which key or parameter it is, in what registry section, and also it's type and it's value before changes.
