Using rnd me's suggestion:
Firefox will recognize the file as an ordinary text file and you'll need to manually navigate to regedit.exe, and then click "OK" to run the file. Firefox will remember which application you used to open a file type last, so simply clicking "OK" will work after that.
Chrome prompts you to save the file with a "Save As" dialog after which point you'll need to click the download tile at the bottom of the window to open the file. If you activate "Always open files of this type" in the tile options menu (which is accessed from the arrow button at the right of the tile), Chrome will instead ask you if you want to "Keep" or "Discard" the file without bothering you with the "Save As" dialog. Clicking "Keep" will run the file.
In Opera (Opera Next 15), the file will automatically be downloaded. You can run the file by double-clicking the tooltip that appears at the top right of the screen after the file has been downloaded or by opening the Downloads panel (through the toolbar button, Opera menu, or by pressing Ctrl+J) if the tooltip disappears on you.
