Registry Tuner is a program for tweaking Windows (9x, NT and so on) by modifying the registry. With the help of RegTuner you can also change the settings of many other programs. The program stores information about registry keys, parameters, their types and comments as a tree. The advantage of this program is that the experienced user can add the new Windows settings known by him or found on the Internet, or she/he can change already existing ones, or can remove them all. The program is completely transparent, i.e. when you change either a key or a 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.
