Hmm... ok. I'm new to make my own .reg-files and I read somewhere that if you put a (-) before the [changes] you uinstall it... Like this: [b]Example.reg[/b] REGEDIT4 INSTALL ; WHAT IS DOES [Changes] UNINSTALL ; WHAT IS DOES [-Changes] So my thought was if use only .reg files with the install info, and no extra code, then I have a explorer shell thats inserts a "-" after every "[" then it would be solved. I want this because then I can easy test new .reg-files (and make my own) and if I don't like it I can switch back fast.
