Merging #338 will create a conflict with this PR. I remember adding some comments in that one too. I am sorry I will clean up the mess later in a few minutes.

Comments aren't a bad thing. Pointless comments that basically just state the name of the variable or exactly what an if statement is doing (i.e. // Check whether value is equal to 0\n if value == 0 {}), rather than explaining WHY something is being done, are the problem I was pointing out.

I'll resolve the conflicts once that's merged, don't worry about it.

Yeah thanks for your efforts @lj3954 . Like I was saying before, they were added because I was explaining my PRs to one of my friends who is a winutil fan by the way. He doesn't have a lot of coding knowledge. He understands the code base easily with more comments. I will clean out all the unwanted comments in a few minutes
