Vim will not stop creating backup files (Windows 8)

Question

I'm using Gvim on Windows 8.1 and even after setting nobackup and nowritebackup in _vimrc, Vim insists on creating those pesky backup files (the .ext~ ones).

I'd like to disable this behavior completely (i.e I want them gone, not just moved to another directory with the backupdir option. I understand that at some point they may come in handy, but I'd prefer a clean directory :p)

Any help would be greatly appreciated!

Note: Oddly enough, the noswapfile option worked as expected.

Answer 1

Type the following to find out where the options are being set:

:verbose backup?
:verbose writebackup?

I had this problem and found that for some reason my .vimrc was sourcing the example vimrc which overwrote my settings.
