I highly doubt that this so called "backdoor" is real. Im not saying that there isnt intentional backdoors, but the one you guys are screwing around with probably isnt the backdoor that the NSA put in... I think even if you screwed the file up, and switched over to linux something in the near future the NSA would still be able to get thru to your computer no matter what.
My guess is that the source codes and everything, the NSA has access to, they know windows, and probably every exploit to it.
