I had an issue pop up recenelty where I needed to burn a DVD, so as usual I went to my ISO`s, right clicked only to find that the burn to iso option was not there . I tried numerous other ways, nope I could not burn an iso in windows 7.
The ISO association had for whatever reason been removed. I think it was down installing 7zip which then thought it would manage the iso suffix.So we need to re-create the file association with windows 7 and also make sure that the reg entry is put back in the registry to do this.. Copy the txt below into a file called “ISO.REG” and save. Once done right click ISO.REG and click merge.

Now again, go to your iso, right click it and you should find the option to Burn ISO is there again.
